摘　　要：梁子湖水源水夏季藻类污染严重,常规饮水处理工艺效果不佳。为提高常规工艺的出水水质,本实验在常规工艺前增加了紫外/过硫酸盐(UV/PS)预氧化措施。结果表明:UV/PS体系具有良好的预处理效果,最终出水浊度、叶绿素a和UV254的平均去除率在常规处理的基础上分别提升了9.96%、17.93%和12.60%;同时UV/PS预处理不会对出水pH、碱度、硬度、DOC、总铝等指标产生较大影响。Conventional water treatment process is ineffective due to algae pollution in Liangzi Lake.To improve the water quality of the conventional process,UV/Persulfate(UV/PS)was used as the peroxidation process in this experiment.Results showed that UV/PS system was an excellent pretreatment process,It makes the final average removal rate of turbidity,chlorophyll a and UV254 raise by 9.96%、17.93%and 12.60%,respectively and wouldn’t have significant impacts on the water pH,alkalinity,hardness,DOC,total aluminum and other indicators.
