摘要
采用铁炭微电解-磷酸氨镁(MAP)沉淀法对垃圾渗滤液进行预处理,实验结果表明,铁炭比为5∶1,pH值为3,反应时间为3 h时,铁炭微电解的COD的去除率为47.5%;在投加药剂n(Mg2+)∶n(PO43-)∶n(NH4+)为1.4∶1∶1,pH值为9,反应时间为1 h的条件下,垃圾渗滤液氨氮去除率达到79.7%。
Iron-carbon micro-electrolysis and magnesium ammonium phosphate（MAP） precipitation were applied to treat landfill leachate in this experiment.The experimental results show when the ratio of iron and carbon is 5∶1,the pH is 3,the reaction time is 3 hours,the removal rate of COD by iron-carbon micro-electrolysis process is 47.5%.When the ratio of n（Mg2＋）∶n（PO3-4）∶n（NH＋4） is 1.4∶1∶1,the pH is 9,the reaction time is 1 hour,the removal rate of ammonium nitrogen is up to 79.7%.
