摘　　要：通过用自制聚硅硫酸铁、聚硅氯化铁、聚合氯化铁铝等高效混凝剂对武汉三个典型湖水进行了混凝除藻实验,发现聚合氯化铁铝除藻效果最好,其中叶绿素浓度为200～300μg L的湖泊水去除率可达99.8%,加入助凝剂和氧化剂后,去除率明显提高。还对其进行了后续过滤实验。Laboratory experiments are conducted in which algae are removed from three typical lake water in Wuhan by efficient selfmade coagulants such as polymeric ferric silicate sulfate (PFSS), polymeric ferric silicate chloride(PFSC) and polymeric ferric aluminum chloride(PFAC). The results show that PFAC is most effective in removing algae and the removal efficiency can beas high as 99.8 percent for lake water with chlorophyll ranging from 200μg/L to 300μg/L. The removal performance is even more obvious when the assistant coagulant polysilicic acid (PS) and oxidant H2O2 are added in.Subsequent filtration experimenthas also been performed
