摘　　要：考察了高锰酸盐预氧化—生物活性炭联用工艺去除藻类的效能。试验结果表明,高锰酸盐预氧化能明显改善混凝工艺对藻类的去除效果,随高锰酸盐投量的增加,混凝工艺对藻类的去除率呈上升趋势。生物活性炭滤池对藻类的去除主要集中在进水端,在20 cm处,去除率可达到60%。高锰酸盐—生物活性炭联用工艺对藻类及有机物有明显的去除,去除率可分别达到99.5%和20.6%。The efficiency of the combined process of permanganate preoxidation-BAC filtration on algae removal has been investigated.The results show that permanganate preoxidation can improve the effect of coagulation on the removal of algae remarkably.With the increase of the dosage of permanganate,the coagulation effect on the removal rate of algae increases,which suggests that permanganate preoxidation enhances coagulation process for algae removal.The algae removal rate reaches 60% at the height of 20 cm by BAC process,which is mainly focalized on the influent end.This combined process has obvious removal capacity for removing algae and organic substances.Their removal rates can reach 99.5% and 20.6%,respectively.
