| 摘 要： | 针对垃圾渗滤液氨氮浓度高、COD浓度高、难降解物质含量高的特点,研究了MAP脱氮-生物处理-混凝组合工艺,考察了不同单元的作用及影响处理效果的因素。试验结果表明,高浓度的垃圾渗滤液经该优化组合工艺处理,污染物的去除率为COD97.5%、BOD599.2%、NH4-N87.2%、E26075.3%。除NH4-N外,其余指标均达到了生活垃圾填埋污染控制标准中规定的二级排放标准值。

| Abstract: | The results of multi-stage treatment of high strength landfill leachate were presented.During the studies MAP(magnesium ammonium phosphate) precipitation method,biological treatment and coagulation-flocculation method were tested.Optimization of treatment was perfomed.The results showed that COD in landfill leachate reduced from (10300mg/L) to (256mg/L),(BOD_5) from (3700mg/L) to (28mg/L),through the multi-stage treatment.The treatment system produced high quality effuent,which reached the secondary discharge standard of pollution control on the landfill site for domestic waste,except (NH_4-N). |
