Problems solved by technology

[0002] The treatment of leachate in urban waste landfills has always been a very difficult problem in the design, operation and management of landfills. Leachate is the product of gravity flow of liquid in landfills, mainly from precipitation and the internal water of garbage itself; The leachate of urban waste landfill is a kind of high-concentration organic wastewater with complex components. If it is directly discharged into the environment without treatment, it will cause serious environmental pollution. For the purpose of protecting the environment, it is essential to treat the leachate , a water reuse technology for landfill leachate MBR membrane treatment, which can effectively treat landfill leachate and recycle it

Abstract

The invention relates to a process technology for recycling water in membrane bioreactor (MBR) membrane treatment of landfill leachate. Through combination of a degradation effect of a conventional facultative tank and an advanced membrane separation technology, the landfill leachate can be effectively treated and reused; the floor area of a membrane bioreactor is small, the quality of the effluent is good, no secondary sedimentation tank is arranged, and operation and maintenance are simple. Community residence waste and domestic wastewater leachate are recycled after being treated, so that awater pollution problem can be solved, water resources can be recycled, full circulation of water resources in an area is realized to the maximum extent, and a purpose of energy conservation and emission reduction is achieved.
