Treatment of Landfill Leachates by Electrodialysis in Three-chamber Cell Divided by Two Membranes
Abstract:
Electrodialysis and Fenton reagent method were combined to decrease the concentration of NH4+-N and CODCr in landfill leachates by means of coupling membrane triple chamber cell.NH4+-N in landfill leachates was enriched in catholyte by electrodialysis,then removed by chemical precipitation.In the meantime,Fe2+ was generated at the Fe anode.H2O2 was dropped into the anolyte to produce Fenton reagent,which could degrade organic compounds and decrease the concentration of CODCr.The experimental results show that the removal rate of NH4+-N in simulated wastewater was up to 80%,and the concentrations of NH4+-N and CODCr in the landfill leachates were decreased from 1 982 mg/L and 2 248 mg/L to 200 mg/L and 127 mg/L,respectively.
