Continuous disinfection at low concentrations can be effectively disinfected and has little effect on water quality. In order to find an effective hot spring water disinfection solution without affecting the water quality, Huang et al. Conduct investigations and experiments again.
For comparative monitoring, Huang Wei et al. sampled 24 pools from the hot springs A and B.
The disinfectant is easy to handle with chlorine particles and sodium hypochlorite solution. The dosage method is divided into manual addition and addition through a water purification cycle device.
Among the specific monitoring methods, hot springs A and B each selected 4 pools and 8 pools for testing. For 4 consecutive days, on the first day, chlorine particles were manually added to maintain residual chlorine 0.20 mg / L; the next day artificial chlorine
Pill, keep residual chlorine 0.50mg / L; the third day, add sodium hypochlorite solution through circulating water purification equipment, keep residual chlorine 0.20mg / L; the fourth day, add sodium hypochlorite solution through circulating water purification equipment, keep residual chlorine 0.50mg / L.
The residual chlorine is detected every half hour and is not sufficient to maintain the corresponding residual chlorine content.
After the disinfectant is added, a microbiological test is performed. After 2 hours, 4 hours and 6 hours, the total number of bacteria in the water and the test result of the coliform group were both 100.0%.
For water quality turbidity testing, hot spring operators reflect and think, different disinfectants and residual chlorine are maintained, and the average turbidity in water in 2 hours, 4 hours and 6 hours is higher than that in hot water without disinfectant.
Elevated, wherein the turbidity of 0.20 mg / L residual chlorine in the chlorinated particles is less than the turbidity of 0.50 mg / L residual chlorine. The turbidity of 0.20 mg / L sodium hypochlorite residual chlorine is lower than the residual chlorine 0.50 mg / L.
There was no significant difference in the turbidity of 0.20 mg / L residual chlorine in the chlorinated particles compared to 0.20 mg / L sodium hypochlorite.
