1. Maintain the water quality of new water put into the swimming pool
It refers to the first release of water into the pool after the pool is built or the first release of water into the pool every swimming season. The water put into the pool is new water without any treatment. New water treatment should follow the following procedures:
After a long period of empty swimming pool, it is easy to grow moss on the wall of the pool, so it must be thoroughly cleaned before releasing water. When cleaning, it is better to use special swimming pool cleaning agent, in order to completely clear the growth of lichen, otherwise it is easy to regenerate after water, it is very difficult to completely clear.
(2) algae suppression and elimination
When new water begins to be put into the pool, when there is a small part of water in the pool, clear water will be put into the algicide.
(3) sterilization and disinfection
After the new water is filled up or 5 hours after the addition of clear water algicide, add pool disinfectant for disinfection. The amount of adding is calculated according to the total amount of water in the pool. When adding, dissolve the disinfectant powder with water first and then sprinkle it evenly.
(4) PH regulation
After the new water is filled up or 3 hours after the disinfectant is added to the swimming pool, test the PH value. If the PH value is lower than 7.5, add the PH regulator to increase the PH to 7.5-7.8.
Clarifying agent dosing quantity per 1000 cubic 1 bottle, for overtime to dilute water clarifying agent then sprinkle evenly, then must open swimming pool circulation equipment, water clarifying agent is the tiny impurities in the water by adsorption of cation to form larger particles, make it into the circulatory system, with the current through the sand filter cylinder make the water clear.
2. Daily maintenance of swimming pool water quality
That is, the normal water quality maintenance or emergency treatment of the swimming pool during the swimming season has the following procedures:
(1) sterilization and disinfection
Most of the water in the swimming pool is sterilized with disinfectant tablets or disinfectant powder. Generally, it is released in two times, one time every day when the library is closed, and the other time 1-2 hours before the opening of the library. This must be done every day, or the water will easily deteriorate.
Usage: at night, the dosage can be 2 kg per 1000 cubic meters. If the water appears green or white phenomenon, it is better to add. Before the opening of the swimming pool, the use of swimming pool disinfectant should be carried out in 0.5-1 hour in advance. The residual chlorine should be tested before the use, and then the dosage should be calculated according to 2 kg per 1000 cubic meters. Use a special dosing device to dissolve 1KG swimming pool disinfectant in 100KG water, and then add it automatically.
(2) PH regulation
Test the PH value of the water before the opening of the swimming pool every day. If the PH value is lower than 7.2, add a PH regulator to increase the PH to 7.5-7.8. Add 10KG of 1000 cubic meters to calculate the increase of 1 degree.
(3) kill and control algae
Generally every 10 days to half a month or so according to 1000 cubic add a bottle of the amount of algicidal agent, to prevent algae growth. If the water body is found to be green or the wall of the bottom of the pool to grow moss and other conditions can be added double algicidal agent, and in the evening when closed to add the usual 2-3 times of disinfectant for treatment.
Generally, clarifying agent should be added once a week. The dosage is 1000 cubic meters per bottle (1KG). After the addition of clarifier, the circulation equipment must be opened for circulation, and the effect is better on the second or third day, which can basically maintain for a week. If the flow of people is large, the water appears cloudy, white or a little green, you can immediately join.
(5) dirt absorption
Clarification can only deal with the suspended matter in the water, suction pollution is to feel the bottom of the pool when there are sand, hair or leaves and other dirty things, so be about to use the pool suction machine to absorb pollution,clean the bottom of the pool.
(6) emergency treatment
If the outdoor pool is in rainy weather, it is good to test the PH value of the water immediately after the rain. If the PH value is lower than 7.5, add a regulator to raise the PH value, and add twice the disinfectant, so as to prevent the algae brought by rain from turning the water green.
3. Maintenance of swimming pool water treatment and circulation equipment
(1) water the swimming pool
If the water level of the swimming pool is too low before opening every day, manual operation is required to replenish water; There is no need to manually operate the automatic water replenishment tank, which will automatically replenish water when the water level is low.
(2) check the circulation pump
Check the circulation pump every day to see if there is any leakage and abnormal noise, if there is, arrange personnel to check and maintain.
(3) check the filter sand cylinder
Check the filter sand cylinder every day to see whether its pipeline switch is in the normal filtering position and whether the multi-way valve of the sand cylinder is in the normal filtering position; Check whether the pressure gauge on the sand cylinder is higher than 1.5 and backwash if it is too high.
(4) check automatic dosing equipment
Check whether the dosing equipment can normally dosing, check whether the online monitor can normally display and control the automatic dosing pump.
