佛山新城水厂ClO_2应用优化及消毒副产物控制

Application of Chlorine Dioxide and Control Method of Disinfection Byproducts in Foshan Xincheng Waterworks

二氧化氯是国际上公认的广谱、高效、安全、环保的杀菌消毒剂,在水厂应用广泛,特别是中小型水厂。佛山新城超滤膜水厂自2006年建成投产后,出厂水一直采用二氧化氯消毒,结合运行十年的二氧化氯设备管理维护经验,总结了ClO_2应用优化实践和消毒副产物的控制方法,可供相关水厂参考。

Chlorine dioxide is regarded as a kind of bactericidal disinfectant with characteristic as wide spectrum, high efficiency, security and environmental protection. It is widely used in drinking water treatment plants, especially in the small- and medium-scale plants. Foshan Xincheng waterworks which adopted the ultrafiltration membrane system as treatment process, was constructed and began to run in 2006. Its effluent was disinfected by chlorine dioxide. Based on the ten-years experiences of management and maintenance of chlorine dioxide disinfection, the application of chlorine dioxide and the control meth- od of disinfection by-products were summarized for reference to similar projects.
