城市垃圾填埋场渗滤液循环回灌处理技术

Recirculation Treatment Method of Leachate from Municipal Solid Waste Landfill Site

城市垃圾填埋场渗滤液经循环回灌处理后，污染物浓度大大降低，填埋场填埋垃圾的湿度增加，稳定速度加快。适量的表面回灌可有效减少渗滤液水量，降低处理规模。与传统渗滤波处理方法相比，此技术投资省，效果好，操作、管理简单，很有应用价值。

After the leachate from municipal solid waste landfill site is treatmented by using recirculation, the concentration decreeases greatly, and the moisture content of the solid waste in landfill site is increased and the rate of landfill stabilization is accelerated. Appropriate surface recirculation can reduce leachate quantity effectively, so the treatment scale is decreased. Compared with the traditional treatment methods, this method need fewer investment, can get better purpose and the operation and management are simpler. It has good practical value.
