It is necessary to establish the consciousness of cherishing water and carry out water resources warning education. For a long time, most people generally believe that water is an inexhaustible "cornucopia", which is wasted in use and does not know how to cherish it consciously. In fact, the water resources on the earth are not inexhaustible. Especially in China, the per capita water resources are not rich, the regional distribution is uneven, and the year is unpredictable, with great inter-annual differences. Coupled with serious pollution, water resources are even more scarce, which is vividly reflected in the repeated water cuts of the Yellow River. National water resources utilization projects such as "Yellow River Diversion Project" and "South-to-North Water Transfer Project" are aimed at solving the water shortage problem in some areas, but we should think deeply: Where can we "divert water from the Yellow River" when the water in the Yellow River is exhausted? The water in the south is polluted. How to "transfer water to the north"? Therefore, people must establish the consciousness of water crisis, take saving water resources as our conscious code of conduct, and carry out water resources warning education in various forms.

Water resources must be developed reasonably to avoid being destroyed. The development of water resources includes the development of surface water resources and groundwater resources. Water resources are used by the state. Therefore, the development of production and domestic water must conform to the relevant provisions of People's Republic of China (PRC) Water Law, and make overall planning and overall consideration. When exploiting groundwater, because the water quality of each aquifer is quite different, it should be exploited by layers; Contaminated diving and confined water shall not be mixed; For exploration projects that expose and penetrate the water layer, layered water sealing and hole sealing must be carried out in strict accordance with relevant regulations to effectively prevent water pollution and ensure the sustainable development of water bodies.

Modern water conservancy projects, such as flood control, power generation, shipping, irrigation, aquaculture water supply, etc. , while exerting one or more economic benefits, it will have a certain negative impact on the natural environment and social environment of the project location, upstream and downstream, estuary and even the whole basin, and may also cause water resources destruction in a certain range. Therefore, since 1970s, many countries have carried out environmental assessment on water conservancy projects. In China, environmental assessment is needed in the feasibility study stage of water conservancy projects. Large and medium-sized projects should prepare environmental impact reports, and small and medium-sized projects with little impact on the environment should prepare environmental impact assessment tables. In addition, the destruction of water resources by some mining industries can not be ignored. For example, every ton of coal mined in coal mining will leak 0.88 cubic meters of water. According to the calculation of 300 million tons of coal mining in our province, the annual loss of groundwater resources caused by coal mining alone is as high as 264 million cubic meters, which has caused great damage to the geological structure of groundwater. For another example, unrestricted deforestation will cause serious damage to vegetation, and it will also have a certain impact on soil and water conservation and surface burial of water resources.

Improve the utilization rate of water resources and reduce the waste of water resources. The key to effective water saving is to reuse water resources by using "reclaimed water". If reclaimed water can be used in the whole society, it will not only bring considerable economic and environmental benefits, but also form a good atmosphere for cherishing water resources in society. At present, many large and medium-sized enterprises have developed and utilized reclaimed water. For example, all mines in Huozhou Coal and Electricity Group use reclaimed water to sprinkle water underground and flush toilets on the ground, which has achieved good economic and social benefits. In addition, the effective utilization of water resources is regulated by economic leverage. Because water control is not in place, many places have flowing water, and some places will "hold bowls and pray". Therefore, it is necessary to install an effective water metering device and implement the principle of using more water and charging more, so as to achieve the purpose of saving water. Urban water quota management is an internationally accepted method. On the premise of scientific verification of water consumption, adhere to the principle of classified treatment. Different water prices shall be imposed on citizens' domestic water, industrial and commercial enterprises' water and government institutions' water, and the excess shall be appropriately raised to cultivate citizens' habit of saving water.

While saving water resources, we should avoid ineffective waste. In winter in the north, water pipes are prone to frost crack and serious water leakage, so special attention should be paid to prevention and inspection; With the development of social economy and the acceleration of urbanization, in order to alleviate the shortage of water resources, in addition to vigorously saving and protecting water resources, inter-basin water transfer has become an inevitable choice for cities in northern China, which will inevitably bring about changes in the relationship between supply and demand of water resources, so water rights trading must be implemented; Since China implemented the "welfare water" system, water has not been treated as an economic commodity. Therefore, in the preparation of water resources, the market mechanism is usually replaced by the control method. At present, we should change our ideas, recognize the natural and commodity attributes of water resources, follow the laws of nature and value, truly treat water as a commodity, rationally allocate water resources by using market mechanisms, and reduce resource waste.

Prevent and control water pollution and realize comprehensive utilization of water resources. Water pollution includes surface water pollution and groundwater pollution. Industrial wastewater, industrial garbage, industrial waste gas, domestic sewage and domestic garbage produced in the production process can all cause water pollution through different infiltration methods. For a long time, environmental incidents caused by direct discharge of industrial production sewage are common, which have brought extremely bad effects on human production and life. Therefore, effective prevention and control of production and domestic sewage should be carried out. Cities can adopt centralized sewage treatment; Industrial enterprises must implement the "three simultaneities" system of environmental protection; According to the different properties of production sewage, corresponding sewage treatment measures are taken. In short, we must resolutely implement the supervision and management system of water pollution prevention and control, adhere to the principle that whoever pollutes will control it, strictly implement the one-vote veto system for environmental protection, promote the sewage treatment work of enterprises, and finally realize the comprehensive utilization of water resources. Water is the material basis for the existence of life on earth, and water resources are the primary condition for maintaining the sustainable development of the earth's ecological environment. Therefore, protecting water resources is the greatest and most sacred duty of mankind.

1 When cleaning cookware and tableware, if the oil stain is too heavy, you can wipe off the oil stain with paper first, and then rinse it with clear water. Washing dishes and chopsticks with rice washing water, noodle soup, overnight tea can remove oil and save water consumption and detergent pollution. 3 Where there is a lot of dirt or grease, you can first use the used tea bag (washed and dried) to smear some cooked oil on the dirty place, and then wipe it with a rag stained with detergent to easily remove the dirt. 4 When washing vegetables, don't wash them directly under the faucet, put them into a water container as much as possible, and adjust the cleaning order. For example, you can peel and remove the mud from the vegetables with skin before entering the external water pipe to prevent the lawn from being replaced in a large area. Don't throw garbage into rivers and lakes, and don't throw away waste batteries to prevent pollution to natural water resources.
