Research on Volume Reduction Technology for Landfill Leachate Membrane Filtration Concentrate
The efficient treatment of landfill leachate membrane filtration concentrate has become an urgent need in the fields of municipal and environmental pollution management.This study focuses on the leachate membrane filtration concentrate from a landfill site in Beijing,employing a"pretreatment-air gap membrane distillation"combined process for its volume reduction treatment.We investigated the impact of different combined processes on the treatment of the concentrate and found that considering practicality,coagulation sedimentation pretreatment offers the best operational and maintenance assurance for the reduction process,reducing the volume of the membrane filtration concentrate by over 80%.Appropriate pretreatment can significantly reduce membrane fouling,enhancing the stability of membrane distillation flux and the concentration factor.
