Operating rules for swimming pool water quality management

First, the swimming pool water quality maintenance

1. The maintenance of fresh water quality put into the swimming pool refers to the first time after the completion of the swimming pool or the first time in each swimming season. The water put in is fresh water without any treatment. Please follow the following procedures for new water treatment:

(1) Cleaning of the swimming pool After the swimming pool has been left vacant for a long time, many people will grow moss on the pool wall (especially at the cracks in the tiles), so the swimming pool must be thoroughly cleaned before the water is discharged. When cleaning, it is best to use a special swimming pool cleaner to thoroughly remove the growing moss, otherwise it will be easy to regenerate after coming out of the water, and it is difficult to completely remove it.

(2) When new algae-killing and algae-inhibiting water begins to be put into the swimming pool, as long as a small part of water begins to exist in the swimming pool, the algae-killing agent will be put into the pool immediately, and the dosage will be calculated according to the total water volume of the swimming pool, and it will be added at one time (2 bottles (2KG) will be put into every 1000 cubic meter, and the algae-killing agent will be sprayed evenly after being diluted with water).

(3) After the fresh water for sterilization and disinfection is filled (if it can't be filled on the same day, add clear water to kill algae for 5 hours), add swimming pool disinfection powder or swimming pool disinfection tablets for disinfection. The dosage is calculated according to the total water volume of the swimming pool, and 4KG is put in every 65,438+0,000 cubic meters. When adding, the disinfection powder of swimming pool should be dissolved in water and sprayed evenly, and the disinfection tablets of swimming pool can be directly sprinkled into the pool.

(4) Adjust the PH value after fresh water is filled (if it can't be filled that day, add swimming pool disinfectant for 3 hours), and test the PH value. If it is lower than 7.5, please add a PH regulator to adjust the PH to 7.5-7.8. Adding 1000 cubic meter can increase the dosage.

High 1 degree.

(5) After clarification, clear water clarifier can be added for clarification. The dosage is calculated as per 1000 m3 plus 1 bottle (1KG). When adding, the clear water clarifier is diluted with water and sprayed evenly. At this time, the swimming pool circulation equipment must be turned on. Clear water clarifier forms tiny impurities in water into slightly larger particles through cation adsorption.

2. The daily maintenance of the swimming pool water quality refers to the normal water quality maintenance or emergency treatment of the swimming pool during the swimming season. Please follow the following procedure:

(1) Disinfection and disinfection Swimming pool water is generally disinfected with swimming pool disinfection tablets or powder, and it is best to put them in two times, one after the end of each day and the other before opening 1-2 hours. This must be done every day, otherwise the water quality will easily deteriorate. Usage: at least 2 kg/1000 cubic meters should be added at night; If the water quality has turned green or white, it is better to add it. Before the swimming pool is opened, it is best to add swimming pool disinfection tablets or powder 0.5- 1 hour in advance. Residual chlorine should be detected before adding, and then the dosage should be calculated according to the ratio that adding 2 kilograms per 1000 m3 can actually increase residual chlorine by 0.5- 1.0 mg/L. For example, in a 500 m3 swimming pool, to increase residual chlorine by 0.5-1.0 mg/L, it is necessary to add1. Special dosing equipment can be used to supplement the medicine in the middle. 100KG water dissolves 1KG pool disinfectant, which will be added automatically.

(2) PH adjustment Check the PH value of water before the swimming pool is opened every day. If the PH is lower than 7.2, use a PH regulator (sodium hydroxide) to adjust the PH to 7.5-7.8, and the dosage is 1000.

Cube plus 10KG can be calculated by increasing 1 degree.

(3) In general, add 1 bottle of clear water every 10 day to half a month to prevent algae growth. If the water body is found to be green or the wall of the pond is covered with moss, double the amount of clear water algaecide can be added immediately, and the impact treatment can be carried out at the end of the night (that is, 2-3 times the usual disinfectant can be added).

(4) Clear water clarifier is generally added once a week for clarification, and the dosage is per bottle 1000 m3 (1KG). After the clarifier is added, the circulation equipment must be turned on for circulation, and the effect is the best on the second or third day, which can last for a week basically. However, if there is a large flow of people and the water is turbid, white or a little green, it can also be added immediately.

(5) Suction clarification treatment can only filter out the suspended solids in the water and make the water clear. Suction means that when you feel dirt such as sand, hair or leaves at the bottom of the pool, you should use the pool suction machine to vacuum and clean the bottom of the pool.

(6) Emergency treatment If the outdoor swimming pool encounters rainy weather, it is best to detect the PH value of the water immediately after the rain. If it is lower than 7.5, add regulator to improve the PH value, and add 2 times disinfectant to prevent algae growth caused by rain and make the water green.

Second, the swimming pool water treatment circulation equipment maintenance

1, replenish water in the swimming pool before the start of the day. If the water level in the swimming pool is too low, it needs to be replenished manually; If there is an automatic water replenishment tank, there is no need for manual operation, and it will automatically replenish water when the water level is low.

2. Check the circulating water pump. Check the circulating water pump once a day to see if there is water leakage and abnormal sound. If yes, notify professionals to check.

3. Check the filter sand cylinder. Check the filter sand cylinder once a day, check whether the pipeline switch is in the normal filtering position and whether the multi-way valve of the sand cylinder is in the filtering position during normal filtering. In addition, check the pressure gauge on the sand cylinder to see if the pressure is higher than 1.5. If it is higher, backwashing is required. Backwashing:

(1) Stop the circulating pump and dosing pump first;

(2) Turn the multidirectional valve of the sand filter cartridge to the backwashing position;

(3) Turn the backwash manual switch to the open position;

(4) Turn on the circulating pump (except the standby pump), and the flushing time is appropriately adjusted according to the pressure of the pressure gauge and the clarity of the water in the mirror, which is generally 10- 15 minutes;

(5) After backwashing, stop the circulating pump, turn the multi-way valve of the sand filter cartridge to the flushing position, and start the circulating pump to run for 2 minutes;

(6) Stop the circulating pump, turn the multi-way valve of the sand filter cartridge to the filtering position, and turn the manual switch for backwashing to the closed position, so that the whole backwashing process ends.

4, check the automatic dosing equipment to check whether the automatic dosing equipment can normal dosing, check whether the online monitor can normal display and control the automatic dosing pump.
