| 摘 要： | 该文采用零价铁强化中转站垃圾渗滤液的厌氧处理方法，考察了进水浓度、初始pH和铁投加量对渗滤渡污染物的去除效果，并探讨了零价铁强化厌氧处理机理。结果表明零价铁的投加可有效强化渗滤液的厌氧处理效果，在进水浓度为22656mg／L、初始pH为7．0、铁投加量为600mg／L的最佳条件下，经过50d厌氧处理，出水CODcr降低至7800mg／L，COD去除率为65．1％。而未投加铁的体系出水CODcr为11560mg／L，COD去除率为48．2％。

| Abstract: | Leachate from waste transfer station was treated by Fe^0 enhanced anaerobic treatment in this paper. Effect of influent concentration, initial pH and Fe^0 dosage on COD removal efficiency was investigated. The results show that leachate effluent CODcr can attain 7 800 mg/L and COD removal rate is 65.1% after 50 days＇ reaction under the optimum operation conditions, when the influent CODc, is 22 656 mg/L, initial pH is 7.0 and Fe^0 dosage is 600 mg/L. While effluent CODa is around 11 560 mg/L and COD removal rate is 48.2 % without Fe^0 dosage. |
