Swimming pool circulating water treatment
Swimming pool water treatment is divided into two parts: physical process and chemical process, both of which are indispensable in swimming pool water treatment.
The physical process is that swimming pool water is filtered and purified by circulating water treatment equipment.
Chemical process refers to adding chemical agents to disinfect, flocculate and remove algae while circulating the pool water, and then making the pool water clean and hygienic through physical process.
Extended data
Documents required to operate the swimming pool:
1, business license.
2. Water quality test report.
3, operating high-risk sports (swimming) approval.
4. Indoor venues need to provide fire acceptance reports.
1, algae killing and sterilization
You need to buy copper sulfate algaecide for the newly-built pool first, and put about 6 kg according to the ratio of 1000 cubic meters, which is about a small bag, and the pool of 500 square meters is about half a bag. You can control this amount by yourself. Pour the algaecide into the sand tank filter and stir it evenly. After cleaning, it will flow into the pool. When the water is turbid, it will be put in 1-2 times a month.
2. Sterilization and disinfection
After adding algaecide, after about 2 hours, add trichloroisocyanuric acid powder for sterilization and disinfection, and add about 1000 cubic meters of water to 2 kilograms. Put it in every morning.
3.PH regulator
After the swimming pool is used for a period of time, the PH value of the pool water is unbalanced, so it is necessary to add sodium hydroxide to adjust the PH value of the swimming pool and test it with a PH tester. The value of 7.5 is PH equilibrium, and it is used when the pH value is greater than or less than 7.5.
4. Add precipitant.
The pool has been used for a long time, and the water is getting turbid. At this time, it is necessary to use polyaluminum chloride to precipitate dirt, and the average level of 1000 cubic meters is 8 kg. Similarly, after washing with a water filter, change the water for 2 hours, let the pool be fully stirred and precipitated overnight.
5. The dirt suction machine sucks dirt
The next day, after settling, walk around the bottom of the pool with a dirt suction machine to suck up the sediment at the bottom of the pool. The injection outside the pool is discharged through the sewage pipe. During step 1-3, if there is a water circulation system, turn on the circulation system to make the drugs evenly dispersed in the water; If there is no water circulation system, try to be uniform.
