摘　　要：回灌技术是一种简单、低廉的渗滤液处理技术,可有效降低渗滤液中COD和氨氮的含量,加速填埋场内垃圾的降解,提高产甲烷速率和甲烷的产量,增大填埋场的沉降速率和总沉降幅度,缩短填埋场的维护期。回灌技术能够适应渗滤液水质水量的复杂变化,在我国西北地区有非常广阔的应用前景。同时,由于该技术在我国利用过程中尚缺乏成熟的工艺设计和运行经验,所以还有待进一步研究和实践。Recirculation is a simple and cheap way for dealing with the landfill leachate.It can effectively reduce the contents of COD and ammonia nitrogen in leachate.It also can accelerate the degradation of landfill waste,improve methane production rate and methane production.It increase the rate of sedimentation and the extent of sedimentation,shorten the maintenance period of landfill.Recirculation is suit for the changes of quality and quantity of leachate and can be widely used in Northwest of China.But there was still lack of maturity in the use of process design and operation experience,so it needed the further research and practice.
