Secondary water supply disinfection requirements: urban secondary water supply disinfection must have inactivated bacteria.
The by-products after disinfection have no effect on water quality and human health. The secondary water supply disinfection technology is economical, reasonable and convenient to manage. The secondary water supply quality meets the requirements of sanitary water quality for drinking water and secondary water supply for drinking water.
The secondary water supply system generally consists of an underground reservoir, a pressurized pump, and a high water tank.
According to the characteristics of the secondary water supply system, the disinfectant dosing point can be selected in the underground reservoir or the high water tank. Add to the underground reservoir, the disinfectant and water can be fully mixed, while ensuring the water quality of the high water tank. When the direct injection is added to the high water tank, the dosage is less, but the underground storage tank will not be disinfected for a long time and will also breed bacteria and algae, which need to be cleaned and disinfected regularly.
Due to its high efficiency, broad spectrum, non-toxicity, no residue, no cancer, and environmental protection, chlorine dioxide has been selected as a water disinfectant by secondary water users.
[Dosage of chlorine dioxide disinfectant in secondary water supply disinfection]
1. High water tank and underground reservoir disinfection:
The chlorine dioxide disinfectant is prepared at a concentration of 100-200 mg/L; it is immersed and disinfected for a period of not less than 1 hour.
2, water disinfection:
When adding the point to the underground reservoir, the amount of chlorine dioxide added is 0.5-1 mg/L.
The dosage of chlorine dioxide is 0.2-0.8 mg/L when it is added to the high water tank.
