Abstract

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.
