摘要
针对目前我国水源普遍受到有机污染的现状,进行了水处理工艺优化组合去除有机污染物的中试研究,重点考察了常规、预氧化+常规、常规+深度处理以及预氧化+常规+深度处理工艺对CODMn、消毒副产物前体物、生物稳定性以及遗传毒性的控制效果。结果表明,CODMn具有良好的代表性和可操作性,可作为水厂工艺选择和运行控制的主要参数;在常规工艺基础上增加臭氧—生物活性炭、活性炭等深度处理工艺是微污染源水处理工艺改进的主要方向。
Aimed at the current organic pollution problem in China, a pilot-scale study on the optimized combination of water treatment processes for removal of organic pollutants was performed. The control effects of the conventional process, preoxidation/conventional process, conventional process/advanced treatment, and preoxidation/conventional process/advanced treatment on CODMn, disinfection byproducts precursor, biostability and genetic toxicity were investigated emphatically. The results show that CODMn is a main representative index for process selection and operation control in waterworks. The com- bination of conventional process and advanced treatment of GAC or O3/BAC is an effective way to treat micropolluted source water.
