摘  要：
通过在北京海淀区六里屯卫生填埋场内设垃圾填埋模拟柱,对新鲜垃圾产生的渗滤液进行了好氧和厌氧两种条件下的自身循环回灌,对两种条件下渗滤液的产生量、常规水质指标进行了测定和分析,初步探讨了好氧回灌处理技术对城市垃圾渗滤液的影响。结果表明,好氧条件下,垃圾填埋柱中渗滤液产生量较少,填埋体系易形成中性偏碱的环境,温度较高,添加污泥与蚯蚓的作用有利于CODCr和氨氮的降解,比厌氧条件提早进入稳定阶段,进而加快了填埋垃圾的稳定化进程。

摘  要：
As leachate in waste landfill may cause secondary pollution, which is one of the key problems for leachate derived from the waste landfill, therefore, the treatment of leachate is an essential part in waste landfill. To evaluate effects of aerobic condition on leachate, we established five columns filled with garbage in LiuLiTun landfill, Haidian District, Beijing. Column 1 was under the condition of anaerobic, column 2 to column 5 were all in aerobic. Approximately one hundred earthworms were added in column 4, and 5 Liters of original leachate were added in column 5. All the columns were re-circulated three times every week, and quantity and normal water index of leachates generated in all the treatments were tested. Chemical parameters that are used in the test included CODCr and ammonia-nitrogen and pH and so on.The results showed that comparison with anaerobic condition, in the aerobic condition, 1,67 percent less leachate generated; 2, there was a trend to form neutral environment; 3, the maximum temperature that system can reach were higher, and less time was needed to this. It may be concluded aerobic condition promote the degradation of leachate greatly. Furthermore, there were beneficial aspects to add earthworm and sludge in column, including declining of the CODCr and ammonia-nitrogen, reaching stable stage earlier and improving the stability course of landfill.
