Technology and advances in leachate treatment of municipal refuse landfill yard

Landfill leachate contained high concentration of pollutants and great variation is often observed in either composition or flow rate. So it is a difficult problem worldwide in field of wastewater treatment. Treatment processes of landfill leachate, including biological method, physico-chemical method and land and recharge disposal are summarized in detail. Characteristics of these methods are analyzed, and many research results got by domestic and foreign scholars and specialists are discussed. Finally some treatment processes common used in this country are introduced and some advices are recommended that the direction way of leachate treatment will combined the biological and physico-chemical method, and the removal of ammonium nitrogen can improve the biological effect.
