摘　　要： 以模拟污水为研究对象,考察了不同絮凝剂(聚合氯化铝、三氯化铁及硫酸亚铁)对污水中磷的去除效果及其影响因素,并对氢氧化铁的吸附除磷规律,以及氢氧化铁与絮凝剂复配除磷的效果进行了探讨,提出了聚合氯化铝、三氯化铁及硫酸亚铁可行的投加量。 The simulative wastewater was employed and the characteristics of phosphorus removal were investigated. Three various coagulants, polyaluminum chloride, ferric chloride and ferrous sulfate, were applied. In this research, the influence of coagulant dosage and other effective factors were discussed. Meanwhile, the adsorption behaviors of ferric hydroxide were elucidated. Moreover, the phosphorus removal efficiency of three different coagulates composed with ferric hydroxide were discussed. Finally, the economical dosage of each coagulant was given.

关 键 词： 混凝 吸附 除磷 复配
