混凝法在滇池蓝藻暴发期净水除藻的可行性研究

Feasibility Study on Algae Removal in Blue Algae Eruptive Time of Lake Dianchi Using Coagulant Sedimentation

采用精制硫酸铝为混凝剂，L93^4正交法安排滇池蓝藻暴发期混凝沉降除藻除净水工艺实验。结果表明，混凝剂种类、水样pH值对蓝藻去除率有很大影响。研究确定了混凝剂除藻最佳操作条件，为混凝法去除蓝藻的工业化提供了理论和实际操作依据。

Aluminum sulfate was used as coagulant agent to treatment of Lake Dianchi blue algae in its blue algae eruptive time. Coagulant sedimentational experiment was arranged with Lg34 orthogonal method. The result showed that the varieties of coagulant agent and pH value of water have great effect on blue algae removal efficiency. The best operational condition to remove blue algae with coagulant sedimentation has been obtained, it offered operational base for industrialization of blue algae removal with coagulant sedimentation theoretically and practically.
