摘要:
为适应中小型农村供水工程消毒需要，提高次氯酸钠产量和电解效率，间歇/串联式次氯酸钠发生器通过两个电极串联实现同电流、相互独立电解，在实验室研究的基础上进行设备定型，并应用在重庆农村地表水厂。研究结果表明，该间歇/串联式次氯酸钠发生器在盐水浓度为3%、盐水体积为120 L、电解时间为300 min条件下，有效氯产量为1 038 g，运行成本可低至6.55 元/kg。设备定型后在重庆农村地表水厂取得了良好的应用效果，当滤前和滤后消毒剂投加量为1.4 mg/L时，有效保障了出厂水和管网末梢水的微生物安全性，且运行成本仅为0.01 元/m3。间歇/串联式次氯酸钠发生器在下一步推广应用过程中需重点提高设备的可靠性、确保适宜的消毒剂投加量，并重视消毒副产物的测试与消毒剂的储存等工作。
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 byproducts should be paid much more emphasis.
