摘要
渗滤液中含有多种对环境有害的污染物质,垃圾渗滤液的性质与垃圾成分、垃圾含水率、降水量、汽温和填埋时间等因素有关,其浓度和性质随时间呈高度的动态变化关系。根据现场运行经验,只有在满足进水化学耗氧量(COD)浓度大于5000mg/L、氨氮浓度小于600mg/L、进水温度大于30℃的条件下,上流式厌氧污泥床(UASB)系统才能取得比较理想的处理效果。
MSW landfill leachate contains manifold pollutants and endangers the environment. The major factors affecting leachate involves variety of waste,moisture of waste,participation,temperature and running time of landfill. The concentration and characteristic of leachate is dynamically changed with time. Based on the landfill site expediency,the UASB system performs well under the conditions that the COD抯 concentration of incoming is greater than 5000mg/l,the NH3-N抯 concentration of incoming is greater than 600mg/l and the temperature of the incoming is hotter than 30℃.
