Leachate from municipal solid waste incineration plant(MSWI leachate)is a kind of wastewater containing various contaminants with high concentrations.Anaerobic digestion is com-monly used to remove organic pollutants in MSWI leachate treatment.In this paper,the perform-ance of microbial electrolysis cell(MEC)for treating MSWI leachate was studied.The experimen-tal results show that compared with a conventional anaerobic reactor,MEC can run smoothly at higher organic loading with stronger organic loading resistance and adaptability.MEC can signifi-cantly enhance the degradation rate of refractory organic matters with large molecular(eg.humus)and reduce their content in anaerobic effluent,which was conducive to the stable operation of sub-sequent treatment units.MEC can increase the methanogenic performance of anaerobic digestion in MSWI leachate treatment,which had efficient energy recovery potential.
