摘　　要：针对北方某市夏季高藻饮水水源特点,采用预氧化处理技术,研究了臭氧、臭氧过氧化氢联用、高锰酸钾和氯预氧化对后续气浮、过滤等常规工艺处理效果的影响.实验结果表明,预氧化能提高后续处理工艺出水水质,降低出水浊度和有机物含量,提高常规处理单元对藻类的去除能力,臭氧、臭氧过氧化氢联用和高锰酸钾预氧化能有效降低消毒副产物生成势,提高工艺出水安全性.For the characteristics of algae-rich water in summer in a north city of our country, the preoxidation treatment technologies are used. The influenee of ozone, O3H2O2,potassium permanganate, chlorine preoxidation to the conventional process such as the post-treatment air floatation and filtration, are studied. The result suggests that, preoxidation can improve the quality of post-treatment water, dilute the turbidity, reduce organic matters and enhance the ability of elimination to algae of the conventional process. The ozone,O3H2O2,potassium permanganate preoxidation can lower the dis-infection by-product precursor as well as strengthen the safety of the conventional process post-treatment water.
