2. Add disinfectant: 3-5KG disinfectant per thousand cubic meters of water (twice the amount of fresh water), evenly spread the medicine and start the circulating pump, and detect the residual chlorine after two hours. If the residual chlorine is less than 0.5ppm, add 1KG disinfectant (per thousand cubic meters of water).
3. Add edible sodium carbonate to adjust the PH value of swimming pool water.
4. If the swimming pool water is turbid or colored, and the turbidity of the water is not up to standard, polyaluminum chloride should be added for adsorption. Can be added through dosing pump. If you want to solve the problem quickly, you can directly add the pool water treatment agent to the pool water. The dosage is 5-8kg per 1000 m3 of water. When adding polyaluminum, firstly dissolve and dilute polyaluminum with water 0/0 times of/kloc-0, start the circulating pump, evenly draw a scoop of water on the surface of the pool water, circulate for 1-2 hours after spraying, then stop the circulation and let it stand for 8 hours before sucking the pool.
5. After the stolen goods deposited at the bottom of the pool are sucked clean, it is best to add water quality stabilizer to keep the pool water stable and not easy to change. Stabilizers can improve the total alkalinity of water, and the PH value can also be increased accordingly. It is advisable to add 50-80 kilograms of water per thousand cubic meters and measure the total alkalinity at 120- 140PPm, and add 1-2 times a month. It can be added when adjusting the PH value.
Extended data:
Matters needing attention in swimming pool water quality management:
1, copper sulfate and disinfectant cannot be added at the same time.
2, disinfectant can't put with alkali at the same time, otherwise the disinfection effect is reduced.
3. When adding polyaluminum chloride, the PH value must be adjusted, otherwise the precipitation will be bad and the water quality will become worse.
4. After adding precipitant, the pollution should be absorbed in time, otherwise it will float to the surface due to hydrolysis of polyaluminum.
