- Abstract:
- In order to meet the disinfection demand of medium and small rural water supply projects and improve the production and electrolytic efficiency of the sodium hypochlorite, the intermittent/series sodium hypochlorite generator with two tandem electrodes which electrolyzed independently, was set up and applied in Chongqing rural surface water plant based on laboratory experiments. The results showed that the intermittent/series sodium hypochlorite generator could reach the minimum running cost of 6.55 yuan/kg, when the operation conditions were brine concentration of 3%, brine volume of 120 L, electrolysis time of 300 minutes and available chlorine production of 1 038 g. The approved equipment also achieved good applied results in Chongqing rural surface water plant. It could effectively reduce the risk of microbial pollution in tap water and the pipe water when dosing amount of disinfectant was 1.4 mg/L before and after the process of filtration, and the operation cost was 0.01 yuan/m3. In the next application process, the reliability of the equipment, the storage and appropriate dosage of the disinfectant, and monitoring of the disinfectant byproducts should be paid much more emphasis.
