摘要
垃圾渗滤液是一种高浓度的有机废水,COD一般可达10 000 mg/L^80 000 mg/L,NH3-N一般在10 000mg/L,且含有十多种重金属离子,垃圾渗滤液的处理一直是污水处理中的难点,笔者对垃圾渗滤液的来源和特点进行了一般的叙述,重点介绍了当前处理垃圾渗滤液的几种基本方法:生物化学法,物理化学法和回灌法.
Landfill leachate is a kind of organic wastewater with high concentration, generally, the COD in it is between 10 000 mg/L- 80 000 mg/L, the NH3 - N in it is about 10 000 mg/L and there are more than ten kinds of heavy-metal ions. The treatment of the landfill leachate is very difficult to carry out, the paper recounts the source and the characteristic of landfill leachate, mainly introduces several basic ways for leachate treatment the present-blo-chemlcal,phy-chemical and reclrculatlon methods.
