I. Functions and mechanisms

Using microorganisms to treat sewage and municipal solid waste is the main direction of environmental protection industry in the future. The mechanism of ecological polymer solution in environmental protection is that photosynthetic flora and yeast flora are dominant, and cooperate with other beneficial microorganisms to synthesize their decomposition, fermentation and synthesis functions, so that harmful gases are harmless in the form of dehydrogenation at first. Through oxidation, reduction, fermentation and other ways to produce antioxidant substances, so as to effectively inhibit the reproduction of pathogenic microorganisms and corrupt microorganisms, eliminate harmful gases such as sulfur dioxide, hydrogen sulfide and methane, deodorize and decontaminate, inhibit the development of harmful eggs and reduce the generation of mosquitoes; Turn harmful and toxic into harmless and non-toxic, and turn harmful into useful. In the fields of environmental protection such as toilet deodorization, domestic garbage utilization, industrial wastewater, stagnant water treatment of stinky lakes, swimming pool purification, etc. The application prospect is very broad and the cost is low. (The picture shows river purification)

At present, the activated sludge method is mainly used for sewage purification, which is the same as the ecological polymer solution purification method, except that there is almost no sludge in the ecological polymer solution. However, the more the water purification level is improved, the more sludge is produced. Why doesn't ecological polymer solution produce sludge? The reasons are as follows: There are effective bacteria for fermentation, decomposition and synthesis in the ecological polymer solution. It is first decomposed by fermentation, and the organic matter is dissolved by water and quickly digested by other bacteria mixed here. At the same time, it produces a large number of antioxidant substances, which will produce self-digestion after several hours of ventilation every day, with the characteristics of self-consumption disappearing. Therefore, it will not appear sludge and the water is clean.

1, treat municipal solid waste, eliminate odor and reduce water pollution;

2. The pollution control benefits are remarkable: organic nitrogen, metal ions, turbidity, COD (chemical oxygen demand), BOD (biochemical oxygen demand) and SS (plankton) are all below the national standard, DO (dissolved oxygen) is increased, and the water quality is improved.

3, heavy metals in sewage can be reduced and toxicity can be eliminated; It can reduce hexavalent cadmium to nontoxic trivalent cadmium.

4. Compared with the common purification pond, using ecological polymer solution to treat sewage can greatly shorten aeration time, improve efficiency, save hydropower resources and reduce energy consumption and cost.

Second, the treatment method

At present, the common methods to treat the environment with eco-polymer solution are:

1, three-stage purification tank method:

2, biofilm method:

3, water spraying method:

The above methods are equally effective for water purification in entertainment places and baths. The water in the bathroom can be recycled after purification.

4. Garbage fermentation method: according to the water content of kitchen garbage (domestic garbage), spread solid ecological polymer fermentation materials to absorb water. It can also contain some bones. Operation method: pour daily garbage into a closed container, sprinkle a layer of ecological polymer fermentation material on it, and then cover it tightly to prevent ventilation. Every day until it is full. The garbage treated with ecological polymer solution not only has no odor, but also can be made into biological fertilizer full of white hyphae after being left for more than 10 days. It is a good organic fertilizer, suitable for planting flowers, vegetables and fruits, without pests and diseases, and can improve the soil. Garbage bio-fertilizer can also be soaked in water for one day, and the extracted liquid fertilizer can not only irrigate fields to increase production, but also purify sewage, killing two birds with one stone.

5. Garbage disposal: the garbage dump can be diluted and sprayed with 100-200 times of ecological polymer solution to reduce rancidity, mosquitoes and flies, and the sewage will not be black and smelly; Extremely smelly sewage, dung ditch, etc. Can be put into ecological polymer fermentation materials to reduce odor, reduce pollution and improve the environment.

Thirdly, the method of treating sewage with ecological polymer solution.

In environmental treatment, the principle of decomposing organic pollutants by the combined action of microorganisms in ecological polymer solution is the same as that of livestock manure treatment, which can inhibit the growth of spoilage bacteria, improve the decomposition path of organic matter, and reduce the dilution of NH3 and H2S and the generation of amine substances. At the same time, some photosynthetic bacteria use H2S as hydrogen donor to consume H2S, eliminate the odor in the environment and reduce the appearance of mosquitoes and flies.

First, the toilet and domestic sewage treatment

Domestic sewage is treated with ecological polymer solution, and the fermentation broth of ecological polymer solution is added to the water source to make the ecological polymer solution penetrate into the sewage. After the triple treatment of precipitation, fermentation and purification, the toilet manure is decomposed and liquefied, without caking, odor and flies. After three days of purification, the transparency of water reaches the standard, and the treated wastewater can be recycled. Taking the domestic sewage of a 50-person/day activity place as an example, the fermentation broth of ecological polymer solution is added into the water source four times in each institute, and the wastewater can be reused. Restaurant wastewater contains a lot of oil, which can be purified within 24 hours after being treated by ecological polymer solution.

Second, the organic wastewater treatment method

Treatment of toilet and domestic sewage: add 1000 times of ecological polymer diluent to the water source every day. After the sewage enters the sedimentation tank, pour 250 times of ecological polymer diluent 3%/m3 into the sedimentation tank. The wastewater discharge port is filled with materials with strong adsorbability (such as porous ceramics), and the diluted eco-polymer solution or fermentation materials are adsorbed to form a "breeding ground" (similar to biofilm effect) where the eco-polymer solution flora proliferates in large quantities, so that the wastewater can be treated. The shape, size and residence time of "breeding ground" depend on the composition and discharge of wastewater. In order to make the organic matter decomposed by the ecological polymer solution flora have sufficient biomass, 0. 1% molasses (brown sugar) can be added to the "farm", and after precipitation, fermentation and purification, the feces can be decomposed and liquefied without caking. After three days, the water quality transparency reached the standard. Restaurant wastewater contains a lot of oil, and the oily wastewater treated by the above method can be purified within 24 hours.

Third, industrial wastewater treatment methods

Industrial wastewater from slaughterhouses, tanneries, starch factories, breweries, paper mills, etc. It can be effectively purified by beneficial microbial preparation of ecological polymer solution. The method is as follows: 250 times of ecological polymer diluent is added at the entrance according to the flow rate of 1% (while flowing), and the wastewater flows into the primary sedimentation tank. An aeration pipe is installed in the pool, and 3% of 200 times of ecological polymer diluent is poured into each cubic meter. The continuous aeration of the aeration pipe makes the wastewater circulate for 24 hours, and materials with strong adsorption (such as porous ceramics) are added at the outlet of the primary sedimentation tank to adsorb ecological polymer diluents or fermented products. A "breeding ground" for large-scale reproduction of ecological polymer solution flora is formed, which flows into the secondary sedimentation tank through the breeding ground of ecological polymer solution, and then flows into the tertiary sedimentation tank for treatment after being treated in the same way. The wastewater is purified, the water quality is clear and can be recycled.

Fourthly, the application of ecological polymer solution to purify fecal sewage.

The wastewater from public toilets is often not treated in time or improperly, which causes serious pollution to the environment and adds a heavy burden to urban sanitation work. According to statistics, the annual fecal output in China reaches tens of millions of tons, and it is increasing at the rate of 10% every year. Especially in recent years, with the rapid expansion of urban construction scale and the sharp increase of urban population, it is more important and urgent to study the treatment of fecal sewage.

The existing methods of manure treatment in China are as follows: first, they are applied to farmland; The second is discharged into water. The former consumes a lot of manpower, material resources and financial resources because of backward means of transportation and long transportation distance, while the latter often pollutes water and harms human health.

Based on the above situation, in order to explore a new way of harmless treatment of feces, we cooperated with a company in June 1996 10, and used the effective microbial flora of eco-polymer solution developed by Japanese professors. According to the principle of micro-ecological engineering, we applied it to the research of toilet fecal sewage for the first time by combining biotechnology with engineering technology, and achieved good results. It laid a good foundation for thoroughly solving the problem of urban feces.

Equipment and working principle

The experimental equipment is a small combined purification tank B of ecological polymer introduced from Japan by emerging companies. It belongs to separation contact type, and the purification tank has three chambers. The first chamber is used to receive fecal sewage accumulated and discharged from the toilet, and ferment and decompose it through the action of microorganisms, that is, decompose organic matter with high molecular weight into organic matter with low molecular weight; The function of the second chamber is to further decompose organic matter into water and CO2 gas; The task of the third room is to further decompose the organic matter with the help of the blower, so that the anaerobic bacteria disappear by themselves and the water body can be purified without pollution.

Test location: a public toilet

According to the actual situation of the construction of public toilets, the relevant departments will arrange test sites to conduct public toilets testing. The purification tank is installed outside the west wall of the toilet, and the surrounding is insulated with asbestos board and straw. Use two urinals for men.

result analysis

In the early stage of the experiment, in addition to the normal use of public toilets, a certain amount of feces and urine was continuously added to the purification tank every day. After calculation, the treatment rate is satisfactory, reaching more than 80%.

The test center is located in the public toilet about 50 meters in front of the gate of Bank of Communications. Traffic is busy all day, and people come and go. Our experiment attracted many people to visit, and more than 80% of them reported that there was no odor. During the test, we monitored the odor intensity at the upper part of the purification tank about 1m by odor evaluation method, which proved that there was no odor and it met the requirements of environmental protection.

This experiment proves that the treatment of fecal sewage by microbial flora in ecological polymer solution can be carried out continuously all the year round. However, it should be noted that nitrifying bacteria in the eco-polymer solution will transform NH4-N into NO3-N, and NO3-N will be denitrified into N2 gas or fixed as microbial nitrogen by fungi. Therefore, this mechanism can also prove that the use of ecological polymer solution can effectively maintain or improve the N, P, K and organic nutrients in garbage. If this kind of garbage is screened and crushed into granular fertilizer, it is also an efficient and high-quality farm manure.

It treats organic matter dissolved in water. In order to prevent the temperature from being too low, it should be kept warm in winter.

The effective microbial flora in eco-polymer solution is used to treat fecal sewage, which is harmless to the surrounding environment, without sludge and odor. The main mechanism of deodorization is that in the third chamber, NH4-N is transformed into NO3-N by nitrifying bacteria, and it is fixed as microbial nitrogen by using NO3-N2 gas in the first and second chambers or other microbial bacteria (such as fungi). Therefore, the volatilization of NH4-N under alkaline conditions is greatly reduced, and the concentration of NH3 in the pond is reduced, so that people can't smell the bad smell.

Using microbial flora of ecological polymer solution to treat fecal sewage is a project with less investment, quick effect, no expansion of land occupation and easy management, which is easy to be popularized and applied in large and medium-sized cities. According to our estimation, the area of a septic tank can be used to build a purification tank, and the fund for building a septic tank plus 1/2 4t dung extractor can meet the fund for building a purification tank. The cost of maintaining the air pump and electricity on weekdays for microbial flora consuming ecological polymer liquid is only 0. 1% of the cost of a dung extractor. The Environmental Sanitation Bureau plans to cooperate with emerging companies again and invite Japanese experts to improve the purification tank and upgrade the standard to CJ 25. 1-89, the water quality standard for domestic miscellaneous water of the Ministry of Construction. Reuse of sewage realizes the unification of economic benefits, social benefits and ecological benefits.

The shortage of water resources in China and the increasingly serious water pollution have caused the shortage of water resources in China. At present, there are two ways to solve the increasing shortage of water resources: on the one hand, save water and improve the utilization rate of water; On the other hand, looking for new fresh water resources. Reusing pollution after treatment is an important way to open up new water resources, which not only saves money, but also is the most feasible from the aspects of ecological resources and environmental protection. Because sewage treatment and reuse is an effective way to solve the shortage of human water resources, it has been widely concerned by governments all over the world. The pollution of Baihe River in Nanyang City mainly comes from the discharge of industrial wastewater and domestic wastewater. The discharge of industrial wastewater is 6 1.28 million t, and the treatment capacity of industrial wastewater is1.701.000 t. Domestic sewage and industrial wastewater are discharged together, including chemical oxygen demand 1 16000t and heavy metals1. At present, there are three kinds of sewage treatment methods: physical and chemical treatment, chemical treatment and biochemical treatment. Physical and chemical treatment is mostly limited to the primary treatment stage to reduce the pollution load and the secondary treatment load, and the treated water quality is difficult to meet the discharge standard. Chemical treatment mainly refers to water treatment agent, which is mostly used for secondary treatment. This method can be used as pretreatment or advanced treatment after biological treatment, but it consumes and pollutes water more or less. Biochemical treatment is widely used at present. Because the biological treatment effect of sewage is good and the cost is low, it will not cause secondary pollution. At the same time, due to the immobilization technology, microorganisms are highly concentrated, and it is possible for us to treat sewage by using genetic engineering to cultivate efficient microorganisms. Eco-polymers can solve the problem of water shortage and even turn toilet sewage into drinking water. There are many reports about the treatment of sewage by ecological polymers at home and abroad. Therefore, it is the purpose of our research to treat the waste liquid after biogas fermentation and the wastewater from biopharmaceutical factories by using ecological polymerization technology, so that they can basically meet the discharge standards and reduce the pollution of wastewater to the environment.

Five, the harmless treatment of kitchen waste

The best way to treat kitchen waste is to use ecological polymer fermentation material (Bokasi) and closed container for anaerobic fermentation, and make domestic waste such as vegetable residue and leftovers into high-quality compost. Fermented garbage will not give off stench, and the fertilizer made of it has remarkable fertilizer effect. At the same time, the oozing liquid is not only an effective liquid fertilizer, but also discharged into the sewer to remove the dirt in the pipeline and purify the water quality. These drains eventually flow into rivers, lakes and seas, which can also strengthen their self-purification function.

1. Material: 2 plastic trash cans, preferably with sealed lids. Ecological polymer stock solution or bocasi.

Each trash can should hold a week's worth of domestic garbage. Take a family of four as an example, the capacity of trash can is 15-20 liters. In order to carry out fermentation smoothly, it is necessary to keep the garbage bin in an anaerobic state as far as possible to avoid excessive water and air. It is best to have two layers to separate the liquid flowing out during fermentation from the garbage, otherwise it will be easy to rot. If there is no double barrel, you can invert a plastic reed at the bottom of the barrel, put a plastic bag on the plastic reed, and open some holes in the bag to let the liquid flow out. Put the garbage in a plastic bag and tie it tightly.

Second, the treatment method:

1, excess water hinders fermentation, so the garbage should be dried as much as possible, and fresh organic garbage such as eggshells and bones should be broken as much as possible, otherwise the air will easily enter when the space is large.

2. After putting garbage into the garbage every time, evenly spread bockas at the ratio of 100: 5, or spray diluent 100 times. If there is more oil and water in the garbage, you can add some water-absorbing materials, such as newspaper scraps.

3. Compact the garbage, remove the air inside, cover it with plastic sheets, and then cover it tightly.

4. Continue to put garbage into plastic bags and tie them tightly every day. The liquid will gradually flow out of the trash can and must be extracted once every two to three days. If the liquid is transparent brown, the fermentation is successful. If the color is cloudy, the dosage of Pokasi should be increased.

5. After the garbage is filled, seal it for a week to make it mature. At the same time, use another bucket and repeat the above operation. In order to take turns to dispose of garbage, two garbage bins are needed.

6. The liquid produced by garbage fermentation is an excellent organic liquid fertilizer, which can be used to water flowers and scrub toilets and closestool. It can also be poured directly into the toilet to remove dirt and odor.

Third, the utilization of fermented waste compost:

Fermented garbage compost can be buried in flowerpots, but it can't touch the roots of plants and should be separated by soil.

The flowers cultivated by fermented garbage compost have well-developed roots, particularly fat plants, bright green leaves, full patterns and bright colors. The flowering period is prolonged by more than 1-2 times. Promoting flowers to protect flowers and fruits, the fruit setting rate can be improved a lot. Weeds in flower beds will not regenerate. All kinds of flowers can use fermented garbage compost, and the effect is excellent.

Four, the benefits of kitchen waste fermentation treatment:

1. For a family, properly handle kitchen waste so that it does not produce malodor, improve family hygiene, reduce the breeding of cockroaches, mosquitoes, flies, ants and mice, and reduce the infection of spreading germs.

2. Fermented garbage can turn waste into treasure, can be used as organic fertilizer, can purify sewers, and can remove odor.

3, avoid environmental pollution, and will not pollute other useful resource garbage. You don't have to take out the garbage every day.

4. Reduce the links of garbage disposal, and reduce the site, labor and fuel costs of landfills and incinerators.

5. Save a lot of money, increase social resources, improve human health and purify the environment.

Retirees, students and workers from communities, schools, institutions, enterprises and institutions can be mobilized to do it together, and designated collection stations can be set up, and the collected fermented garbage can be sent to the garden bureau and agricultural machinery station for fertilizer use. Do one more thing, why not?

Attachment: Method and Application of Fermenting Rice Washing Water

Rice washing water can also be effectively used after being fermented by ecological polymer solution. The method is: put a pinch of bocas or stock solution and brown sugar into the rice washing water, and stir and ferment in a closed way at a temperature of about 30 degrees. After 4 or 5 days, the rice washing water turned light brown and smelled of fermented alcohol. Using it to dilute the flowers by 300 times can make them huge, colorful and prolong the flowering period. If it is discharged into the sewer, it can remove the dirt in the pipeline, purify the household drainage and eliminate the odor.

What is kitchen waste?

Kitchen waste includes: leftovers, leaves, peels, bones, seafood shells, peanut shells, Chinese medicine residues, leaves and other organic substances. But it does not include liquids such as rice washing water and leftovers soup.

As long as one percent of us use eco-polymers, sewage can be purified to a considerable extent. As long as we spare a little time every day, the country can save a lot of money and use it in more needed places.

6. Application of ecological polymers in hotels.

Using microorganisms to control air pollution, sewage and municipal solid waste is the main direction of environmental protection industry in the future. The mechanism of eco-polymer solution in environmental protection is that photosynthetic flora and yeast flora are dominant, and cooperate with dozens of other beneficial microorganisms to integrate their functions of decomposition, fermentation and synthesis, so as to make harmful gases harmless in the form of dehydrogenation; Through oxidation, reduction, fermentation and other ways to produce antioxidant substances, effectively inhibit the reproduction of pathogenic microorganisms and corrupt microorganisms, eliminate harmful gases such as sulfur dioxide, hydrogen sulfide, methane, formaldehyde, deodorize, prevent mold, decontaminate, inhibit the development of harmful eggs, and reduce the generation of mosquitoes; Turn harmful and toxic into harmless and non-toxic, and turn harmful into useful. In the fields of environmental protection, such as toilet deodorization, domestic garbage utilization, industrial wastewater treatment, stinking lake stagnant water, swimming pool purification, etc., the application prospect is very broad and the cost is very low.

Ecological polymer solution can effectively decompose dirt (organic matter) and odor components, and can inhibit the reproduction of harmful bacteria. You can spray it with a sprayer at home, or you can put the stock solution in the water for washing mops and rags. The concentration depends on the degree of odor or dirt. In places where mold and miscellaneous bacteria are easy to breed, spray it several times more, and the concentration is higher. The heavier the smell or dirt, the greater the concentration. It should be used before the value of mold and miscellaneous bacteria increases, and the effect is the best. Diluent of 100 times was used for the first few times, and then the concentration was gradually reduced. Its principle is to make beneficial bacteria in the stock solution precipitate and multiply as soon as possible, so as to decompose and eliminate mold and miscellaneous bacteria as soon as possible, quickly remove odor, eliminate harmful substances in the air and purify the air. Use it once a day in places with heavy smell, much dirt and sticky humidity, and use it 1-2 times a week in other clean places.

Place of use: living room, karaoke room, hotel corridor, carpet, living room space, toilet, bathroom, air conditioning outlet, kitchen, floor, washbasin, exhaust fan, range hood, drain outlet, corner corner, windowsill, balcony, etc.

Caution: Do not use it with other disinfectants, such as disinfectants. The appearance of white silk on the surface will not affect the use. Shake well before use. Put it in a cool, dark place. If there is gas, it should be released.
