| 摘 要： | 取纯培养条件下的铜绿微囊藻水样，分别用三氯化铁、聚合氯化铝、硫酸铝等3种药剂作混凝去除铜绿微囊藻烧杯试验，结果表明：聚合氯化铝混凝效果优于其他2种药剂，具有药剂投加量少(30～40mg／L)、矾花形成快、矾花沉降性能好、除藻效率高等特点．在聚合氯化铝最佳混凝条件下，投加聚丙烯酰胺助凝试验，发现添加6mg／L的聚丙烯酰胺只使除藻效率在原有基础上提高3％．铜绿微囊藻水样的pH对聚合氯化铝的混凝效果有明显影响，产生最佳混凝的pH值范围为6．0～7．0之间．

| Abstract: | Removal of Microcystis aeruginosa from the water sample coming from pure culture through cup flocculation experiments using ferric chloride, poly-aluminium chloride and aluminium sulphate as flocculants respectively had been investigated, the results showed that poly-aluminium chloride achieved the highest removal rate of alga and turbidity in the least dose (30 mg/L) as compared to the other two flocculants. Under optimal conditions of poly-aluminium chloride, addition of 6 mg/L PAM as an aide coagulant only raised alga removal rate by 3%. Changes of the sample pH markedly influenced the effects of poly-aluminium chloride and the best pH values varied between 6.0 and 7.0. |
