Study on upgrading and engineering design of leachate treatment facilities in a landfill in Beijing

Abstract

This paper systematically introduces the technical route and engineering design practice of upgrading and reconstruction of a landfill leachate treatment station in Beijing. The Water balance tank+ Two-stage A/O external MBR+ Nanofiltration+ Reverse osmosis process is adopted to realize that the effluent quality of landfill leachate treatment meets the requirements of B emission limits in Table 1 of Beijing local standard DB11/307-2013, which can provide reference for engineering design and research on the selection of technical route for upgrading landfill leachate treatment.
