Water quality treatment of swimming pool
1. After the newly used swimming pool is filled with Bai water, 5kg copper sulfate is added into the pool according to the amount of Du per thousand cubic meters of water. After adding Zhi, the next step of treatment can be carried out after 24 hours.
2. Add Dao disinfectant: add 3-5kg of disinfectant per thousand cubic meters of water (double the amount of new water). When dispensing, evenly pull and sprinkle the disinfectant and start the circulating pump. After two hours, detect the residual chlorine. If the residual chlorine is less than 0.5ppm, add 1kg disinfectant.
3. Add sodium carbonate to adjust the pH value of swimming pool water.
4. If the swimming pool water is turbid or has color, when the turbidity of water can not reach the standard, polyaluminum chloride should be added to solve the problem. It can be added through the dosing pump. If you want to solve the problem quickly, you can directly add the pool water treatment liquid in the pool water. The dosage is 5-8KG per thousand cubic meters of water. When polyaluminum is added, dissolve and dilute polyaluminum with 10 times water, start the circulating pump, pull the water spoon evenly on the surface of the pool water, recycle for 1-2 hours after sprinkling, stop the circulation, and suck the pool after 8 hours of standing.
5. If you want to keep the pool water stable and not easy to change, it is better to add water quality stabilizer after the stolen goods precipitated at the bottom of the pool are sucked dry. The stabilizer can improve the total alkalinity of water, and the pH value can also be increased accordingly. The addition is 50-80kg per thousand cubic meters of water, and the total alkalinity is 120-140ppm, which is added 1-2 times a month. It can be added when adjusting pH value.
Matters needing attention in water quality management of swimming pool:
1. Copper sulfate and disinfectant can not be added at the same time.
2. The disinfectant should not be placed with alkali at the same time, otherwise the disinfection effect will be reduced.
3. When adding polyaluminum chloride, it is necessary to adjust the pH value, otherwise the water quality will become worse if the sedimentation is not good.
4. After adding precipitant, it is necessary to absorb dirt in time, otherwise it will float on the water surface due to polyaluminum hydrolysis.
