Trichloroisocyanuric acid powder can be very benefits for environment.

First, the selection of disinfectants should meet the following requirements:trichloroisocyanuric acid 87 90 1 - Yuanfarchemical  

(1) Strong sterilization and disinfection ability, and has a continuous sterilization function;  

(2) Do not cause water and environmental pollution, do not change the water quality of the pool;  

(3) No stimulation or very little stimulation to human body;  

(4) Small corrosion of building structure, equipment and pipelines.  

Second, the swimming pool water should be disinfected with ammonia disinfectant. 

Current, the disinfectant that our country swimming pool uses contains hydrogen to have: liquid ammonia, drift fine powder, drift water, strong hydrogen essence to wait.  Bleaching fine powder because of residue, blocked pipes, affecting water quality, also gradually eliminated.  The ammonia content of drift water is very unstable, and its available ammonia will decrease gradually with the influence of environment, temperature, humidity, light and storage time.  When using liquid chlorine disinfection, there should be leakage prevention measures, including water treatment room should be far away from the swimming pool and closed, there is an emergency alarm device in the room, etc.  Vacuum automatic feeding method should be adopted for liquid ammonia, and a device should be set for hydrogen to fully mix and contact with pool water;  Due to the colorexic group, the strong hydrogen essence gradually decomposes in water to release the secondary amino acid, and the cyanourate left has a stabilizing effect on the available ammonia in water.  It's non-toxic and fairly stable to store.  In recent years, quite a number of swimming pools in China use TCCA as a disinfectant for swimming pool water.  

The 3rd, be in conditional and need circumstance below, can use ozone, ultraviolet ray or other disinfection method. 

When using ozone or ultraviolet disinfection, should also be supplemented with hydrogen disinfection, in order to maintain the continuity of disinfection.  

Fourth, the hydrogenation amount of swimming pool water (including the continuous supply of new water for children) is calculated and determined according to the free residual hydrogen amount in the pool water is 0.3-0.5mg/L.

The hydrogenation amount of immersion foot disinfection pool water is calculated and determined according to the free residual hydrogen amount in the pool water is 5-10mg/L, and the dosing time is best 1-2 hours before opening.  When the swimming place is open, the residual hydrogen in the swimming pool water should be measured regularly and a good record should be made.  If conditions permit, residual hydrogen should be measured every 2 hours when indoor swimming places are open.  When outdoor swimming places are open, the residual ammonia should be measured every hour.
