Microaerophilic recirculation treatment method for membrane-separation concentrated solution of garbage leachate
InactiveCN101767877AIncrease temperaturePromote formationTreatment with aerobic and anaerobic processesHigh concentrationOrganic acid
The invention relates to a microaerophilic recirculation treatment method for a membrane-separation concentrated solution of garbage leachate, which comprises the following steps: the concentrated solution is uniformly distributed on the surface layer of the recirculation area via an overhead tank and water distribution pipes, and discharged into a drain pipe via an overlaid soil layer, a garbage landfill layer and a pebble layer; and a forced draft is introduced into the recirculation area to accelerate the organic matters in the concentrated solution and garbage to decompose, and the concentrated solution is finally discharged into a stabilization pond. Since the landfill layer provides a microaerophillic environment, acid fermentation, high concentration and organic acid accumulation are inhibited, thereby accelerating the removal of COD and NH3-N; and the abundant microbial populations in the landfill layer is beneficial to the degradation and stabilization of the landfill layer. Thus, the invention has strong capability for resisting hydraulic load variations and favorable recirculation treatment effect on the concentrated solution.
