摘　　要：本论文以经过实验室处理的粉煤灰作为吸附剂，对垃圾渗滤液进行预处理，取得了较好的效果．实验结果表明，垃圾渗滤液经过粉煤灰预处理后，CODcr从12000～25000mg／L降低到3000mg／L左右，氨氮由400～450mg／L降低到50～70mg／L，重金属Cu、Cd、Zn、Pb、Cr也分别从7．0、3．5、3．5、10．0、5．5mg／l。左右降至低于国家污水综合排放标准（GB8978—1996）中的规定．The experimental study on pre-treatment of Ihe landfill forward in this paper. The results showed that after having leachate with treated Coal ash was put been treated with the coal ash the concentration of CODcr and the ammonia were greatly reduced in the landfill leachate. The CODcr with concentration range from 12000 mg/L to 25000mg/L was reduced to about 3000mg/L anti the ammonia with concentration range from 400 rag/l, to 450 rag/l, was reduced to less 70 mg/L. The indexes of Cu, Cd, Zn, Pb and Cr of treated landfill leachate were all measure up （GB8978- 1996） while their original concentrations were respectively 7.0 mg/L, 3.5 mg/L, 3.5 mg/L, 10.0 mg/L and 5.5mg/L.
