摘要
考察了采用硫酸铝(Al2(SO4)3.18H2O)和三氯化铁(FeCl3.6H2O)为混凝剂对富营养化景观水中磷和藻类的去除效果,并通过正交试验确定了最佳反应时间、混凝剂投加量和pH值。试验结果表明,两种混凝剂单独使用均可有效去除水中藻类和磷酸盐。Al2(SO4)3比FeCl3更适用于混凝沉淀去除富营养化景观水体中的藻类和磷。
Removal efficiency of phosphorus and algae from landscape water was investigated with aluminum sulfate(Al2(SO4)3·18H2O) and ferric chloride(FeCl3·6H2O) as coagulants,and optimal reaction time,dosage of coagulant and pH were determined by orthogonal test.The result indicated that both coagulants could remove algae and phosphate effectively.Aluminum sulfate was more suitable for removal of algae and phosphorus by coagulation and sedimentation than ferric chloride.
