摘要
通过模拟试验研究了垃圾填埋场渗滤液分别回灌到不同高度的垃圾柱之后,柱内的有机污染物降解变化规律。结果表明:回灌处理法对有机物有较好的处理效果,对回灌渗滤液中有机物的去除效果随垃圾堆体高度的增加而增加;单位矿化垃圾可承受的有机污染负荷有一限值,当在一定时间内因回灌而进入垃圾堆体中的有机污染负荷超过这一限值时,渗滤液回灌处理系统将遭到破坏且不易恢复。
Simulation test was made to investigate the variation in organic pollutants degradation after the recirculation of leachate from refuse landfill to test columns with different height. The result showed that leachate recirculation is efficient for the removal of organic pollutants, and the removal efficiency of organics in the leachate is increased with the increase of refuse dump height in the columns. The organic pollutants loading bearable to the unit mineralized refuse shall be limited to a certain value, and if the organic pollution loading in the columns exceeds the limit value in a definite time, the leachate recirculation system will be damaged and is not easy to recover.
