重金属捕集剂在废水处理中的研究进展

Research Progress of Heavy Metal Collectors in Wastewater Treatment

在众多的重金属废水处理方法中,重金属捕集剂法具有反应效率高、污泥沉淀快、含水率低、残渣稳定以及选择性良好等优点,特别是对重金属浓度较低的废水,也有明显效果,因而成为国内外重金属废水处理研究的热点。文章旨在综述DTC类重金属捕集剂的研究与应用进展,简述了捕集剂与重金属作用的基本原理,并阐述了其在废水处理中的应用现状及主要影响因素,总结了重金属捕集剂法处理重金属废水存在的问题,并提出一些重金属捕集剂未来的研究方向。

Among the many heavy metal wastewater treatment methods,the heavy metal collector method has the advantages of high reaction efficiency,fast sludge precipitation,low water content,stable residue and good selectivity,especially for wastewater with low concentration of heavy metals.Therefore,the heavy metal collector has become a hot spot in the research of heavy metal wastewater treatment at home and abroad.This paper aims to review the research and application progress of DTC heavy metal collectors,briefly introduce the basic principles of the action of collectors and heavy metals,and explain its application status and main influencing factors in wastewater treatment,and summarize the problems in the treatment of heavy metal wastewater by agent method,and put forward some future research directions of heavy metal collectors.
