摘　　要：源水的富营养化将严重影响常规给水处理厂的运行,使得出水水质不能保证。为此,开展了KMnO4、H2O2、ClO2 的预氧化研究。结果表明,投加这三种氧化剂均能显著提高对水中藻类、浊度、有机物的去除率,对细菌及大肠菌群也有较好的去除效果,但投加KMnO4 会增加出水色度,采用ClO2 作氧化剂则成本较高,相比之下H2O2 是一种较为理想的预氧化剂。Eutrophication of source water seriously influences the operation of conventional water treatment plant, and fails to guarantee the treated water quality. And so, use of KMnO_4, H_2O_2, and ClO_2 as pre-oxidants was studied. The result shows that the three oxidants can significantly improve the removal rate for algae, turbidity, and organic substances from water, and are efficient in removal of bacteria and coliform group. However, addition of KMnO_4 will increase the color of the treated water, and use of ClO_2 as oxidant will cause the high cost. By comparison, H_2O_2 is a more favorable pre-oxidant.
