摘　　要：研究了一个城市垃圾填埋场渗滤液污染物浓度的时间变异以及渗滤液未作任何处理的情况下对水环境的影响。结果表明，该场渗滤液中污染物的浓度大多随填埋时间增加而升高，或在3年左右达相对稳定状态后作小幅度波动，渗滤液污染导致水环境中大肠菌群增加－2个数量级，化学耗氧量，硝酸盐氮，氨氮等也呈明显增加趋势，提出以覆土植树法与渗滤液回喷法相结合防治该场渗滤液污染。A case study has been made on the Xiaowupu garbage burying-ground of Changde City to find out how the concentration of pollutants in the leachate changes with time and what environmental effect the undisposed leachate has on water.The results show that the concentration of most pollutants in the leachate of the junkyard rises with time's passing or flunctuates mildly after reaching a relatively stable state in some three years,that as a result of the leachate pollution,the colon bacilli have increased by 1-2 orders of magnitude,and the volumes of chemical oxygen consumption,nitrate nitrogen and ammonia nitrogen have also increased remarkably.So tree planting and leachate backspraying are supposed to be combined to prevent and control the leachate's pollution.
