| 摘 要： | 结合我国实际和生活垃圾填埋场产生的渗滤液对环境的影响，对一种能够有效处理渗滤液的回灌方法进行了初步研究．回灌试验考虑到渗滤液水质复杂多变，具有高COD含量、高NH3-N含量和高重金属离子的特点，主要采取厌氧回灌．研究内容主要有两个方面：一方面，对试验垃圾渗滤液进行回灌试验，研究回灌法对垃圾渗滤液中CODcr、NH3-N、NO3-N、NO2-N等各项指标的去除效果；另一方面，主要通过改变pH值和改变依据CODcr调节的水力负荷值来研究对渗滤液回灌效果的影响因素。

| Abstract: | This article is about the preliminary research on an effective treatment of leachate by recharge method,considering the reality of our country and the impact of leachate on environment. The experiment is mainly anaerobic recirculation, because the water quality of leachate is complex, with high CODer and high NH3 - N concentration as well as high heavy metal ion concentration. The experiment mainly consists of two aspects ： on the one hand, the recirculation of the leachate and the study of its removal effect of CODer, NH3 - N, and other indicators in leachate; on the other hand, the study of the factors of leachate recirculation by changing pH and hydraulic load referring to CODcr. |
