垃圾渗滤液浓缩液处理现有技术分析

Treatment of Concentrated Landfill Leachate:An Analysis of Current Technologies

垃圾渗滤液浓缩液的处理已经成为一个急迫的环境问题。目前,浓缩液的处理方式主要包括回灌、浓缩以及无害化处理3种。其中,浓缩处理主要包括基于膜技术和蒸发技术的减量方法;无害化处理主要涵盖混凝/电絮凝、吸附以及高级氧化等技术。总结了目前的渗滤液浓缩液处理技术发展现状,以期为后续的研究提供基础。

The treatment of concentrated liquid filtrate has become an urgent environmental problem.At present,there arethree common treatment techniques,including recharge,concentration and harmless treatment.Among them,the concentratedtreatment mainly includes the method of reducing the technology based on membrane technology and evaporativetechnology.The non-hazardous treatment mainly covers the techniques of coagulation/electroflocculation,adsorption andadvanced oxidation.This paper summarizes the present situation of the development of concentrated liquid treatment technologyfor concentrated liquid filtrate,which provides the basis for follow-up studies.
