摘要:随着城市化进程的不断加快,我国城市人口的数量与日俱增,所以垃圾的数量也在不断增加。垃圾转运站中,在垃圾堆积和处理的过程中会产生渗滤液,这种高浓度的有机废水对环境有较大的危害,因此需要通过相应的处理才能排放到环境中。基于此,本文从中心城区垃圾运转站渗滤液来源和特点入手,首先分析城区垃圾运转站渗滤液处理的难点,然后着重探讨中心城区垃圾运转站渗滤液处理技术,希望可以借此给我国城区垃圾渗滤液处理的相关研究提供一定参考。

Abstract: With the accelerating urbanization process,the number of urban population in China is increasing day by day,so the amount of garbage is also increasing.In the garbage transfer station,leachate is generated during the process of garbage accumulation and treatment.This high concentration of organic wastewater is harmful to the environment and needs to be treated to discharge into the environment.Based on this,this paper starts from the source and characteristics of leachate in the garbage operation station in the central city,first analyzes the difficulties of leachate treatment in the urban garbage operation station,and then focuses on the leachate treatment technology in the garbage operation station in the central city,hoping to give the urban waste in China.Related studies on the treatment of leachate provide some reference.

1 中心城區垃圾运转站渗滤液来源和特点
城市垃圾运转站是整个城市垃圾处理的核心系统,他们会把垃圾进行压缩以此来减少体积,但是在压缩的过程中垃圾中的部分水分会渗出,同时还有垃圾运转站中地面的清洗水,两者共同组成了垃圾渗滤液,这些液体中含有大量的污染物,不能直接排放到环境中,所以需要采取相应的处理措施。
结合当前的实际情况,城区垃圾运转站渗滤液的特点主要表现在以下几点:(1)水量小且波动较大,垃圾渗滤液的产生与垃圾种类和压缩程度等原因有着密切的关系,在垃圾运转站的作业高峰时间上产生较多,而其他时间产生较少,另外,垃圾渗滤液一般不会超过垃圾总量的10%,产生量并不大,所以城区垃圾转运站渗滤液的水量特点呈……
