Landfill Leachate And Concentrated Leachate Treatment Technology Route Of Research In Beijing

At present, a total of29in Beijing city garbage treatment facilities, of which only18garbage treatment facilities have the leachate treatment system. Leachate treatmentability insufficiency. On the other hand, leachate composition is complex, thedifficulty in processing, processing facilities of large investment, high operation cost.In2008the State Environmental Protection Department promulgated the " Standard forPollution Control on the Landfill Site of Municipal Solid Waste"(GB16889-2008).Discharge standard of the total nitrogen of this standard has higher demands. Thetraditional technology of leachate treatment facilities, some of the early construction of thecannot reach the new emission standard. At the same time, the landfill by membranepermeation process as the final leachate treatment technology.But concentrated liquidgenerated by this process is difficult to solve.This paper in order to solve the Beijing leachate treatment capacity is insufficient,the existing landfill facilities effluent leachate treatment is unable to achieve the "Standard for Pollution Control on the Landfill Site of Municipal Solid Waste "(GB16889-2008), concentrated leachate treatment process to deal with problems.Research on the topic of domestic leachate and concentrated leachate technology,from the point of view of technical applicability, economy, stability, water index angle,selective preference the leachate and concentrated leachate treatment technology routefor Beijing. The subject of research has a positive meaning to enhance Beijingleachate treatment technology to reduce pollutant emission of landfill leachate.
