摘　　要：本文研究了聚合硫酸铁与无机混凝剂在除浊、pH 适用范围、COD 去除、污泥脱水性能等方面的性能比较。试验表明,PFS 具有投药量少,pH 适用范围宽,浊度、色度和COD 去除率高,水中残留铁离子少,水解产物脱水性能较好等优点,是一种高效、应用较广的水处理剂。The Polyferricsulfate (PFS) and inorganic floucculants on the turbidityremoving,the appropriate pH range,COD removing,sludge dewatering andso on have been compared in this paper.The experiment results indicatedthat PFS is more advantages than other inorganic flocculants in water treat-ment,such as less dose,wide spectrum of pH,high removal efficiency inturbidity,Color and COD,less ferric ion remains in water and its hydrolysisproduct with satisfactory dehydrolysis,so,it is a water treatment reagentwith high efficient and widely applied.
