摘　　要：现代工农业的快速发展使得去污水、除废水的需求只增不减。磷元素因其在低浓度下仍能引起水体富营养化而受到广泛关注。去除低浓度磷的传统方法不多且存有一定缺陷,电絮凝作为一种绿色高效的电化学方法可弥补之前处理工艺的不足。因此,从电絮凝除磷技术的原理及其发展历程入手,论述了该技术不同操作参数,包括阳极材料、电流密度、电解时间、pH、初始磷酸盐浓度及流速等对电絮凝除磷的影响,举例说明了该技术在实际去除水中低浓度磷中的应用,总结了近年来去除低浓度磷酸盐的电絮凝优化工艺及发展状况,最后指出电絮凝去除低浓度磷技术的局限性,这将有助于电絮凝技术的研究、开发及应用,为减少我国污水中磷排放,维护水生环境的绿色健康提供支持。The rapid development of modern industry and agriculture has made the demand for sewage and wastewater removals.Phosphorus has received extensive attention because it can still cause the eutrophication of water bodies at low concentrations.There are many traditional methods were used to remove the low-concentration phosphorus.Electrocoagulation as a green and efficient electrochemical method can be used to meet the demand for phosphorus.Hence,this paper aims to introduce the development of electrocoagulation,which removed low-concentration phosphorus in testing and practical application.The effect of different operating parameters on the electrocoagulation removal of phosphorus was illustrated,and the electrocoagulation optimization process for removing low-concentration phosphate was summarized.Finally,the limitations of electrocoagulation for removing low-concentration phosphorus were also pointed out.This paper will contribute to the development and application of electrocoagulation,provide better measures for reducing phosphorus discharge of sewage,and maintain a green and healthy aquatic environment.
