摘要
垃圾渗沥液是一种难处理的高浓度有机废水,其所含污染物的资源化利用被认为是垃圾渗沥液处置的重要研究方向.从垃圾渗沥液有机物组分出发,重点综述了通过萃取法、吸附法、膜法、沉淀法、离心法等方式直接回收,以及通过厌氧发酵法、电化学法、物理化学法、生物转化法等方式间接回收垃圾渗沥液中有机物的资源化研究进展,讨论了垃圾渗沥液有机质回收的必要性及技术可行性,对VFA、HS、甲烷、氢能、电能、PHA等回收产物的基础应用进行了概述,总结了垃圾渗沥液有机物资源化技术工程应用现状,分析了各相关技术的工程化生产的可行性,提出了试验阶段转向工程化应用的技术壁垒,从经济性、技术可行性角度提出了建议,并对垃圾渗沥液资源化利用前景提出展望.
Abstract
Landfill leachate is a kind of high-concentration organic wastewater that is difficult to treat.Different from conventional wastewater treatment paths,the resource utilization of pollutants is considered to be an important research direction for landfill leachate disposal.Starting from the organic composition of landfill leachate,the research progress of direct recovery of organic matter in landfill leachate by extraction,adsorption,membrane,precipitation,and centrifugation,as well as indirect recovery of organic matter in landfill leachate by anaerobic fermentation,electrochemical,physicochemical and biological conversion is summarized.The necessity and technical feasibility of recycling organic matter from landfill leachate are discussed.The basic applications of recycled products such as VFA,HS,methane,hydrogen,electric energy and PHA are summarized.The engineering application status of organic matter resource technology from landfill leachate is also summarized.In this paper,the feasibility of engineering production of each related technology is analyzed,and the technical barriers of turning to engineering application in the test stage are put forward.Suggestions are put forward from the perspective of economy and technical feasibility.The prospect of resource utilization of landfill leachate is prospected.The feasibility of engineering application of related technologies is also analyzed.
