摘　　要： 考察了4种聚铝絮凝剂絮凝沉降铜绿微囊藻的效果,发现编号为HPACS02的聚铝絮凝剂除藻效果最好,并进一步研究得知HPACS02在pH 7.5时絮凝除藻的效率最高。在采用HPACS02作为絮凝剂时,如果少量投加滑石、海泡石或高岭土等粘土矿物会对铜绿微囊藻的絮凝沉降产生增效作用,其中滑石的助凝效果最好。 The effects of 4 kinds of HPACs for the flocculation of the Microcystis aeruginosa were investigated, in which a kind of HPAC named HPACS02 was found to be a best flocculation for the sedimentation of cyanobacterial cells. It was shown that the flocculation efficiency of M. aeruginosa by HPACS02 reached the maximum value at initial pH 7.5. The concerted effects for the sedimentation of M. aeruginosa＇ s cells were observed when HPACS02 and clay of talc, sepiolite or kaolin were simuhaneously added, in which talc was found to be the best.
