| 摘 要： | 对两个城市的小型垃圾转运站现状进行了分析,并对其渗滤液产生量及渗滤液性质进行了监测。结果表明:小型垃圾转运站转运量小、分布密集;深圳垃圾转运站产生的混合污水并入城市污水管网,常州的小型垃圾转运站,产生的渗滤液及冲洗废水50%直接排入了河道;转运站排放的混合污水,除汞外,其他指标远超GB 8978-1996《污水综合排放标准》及CJ 3082-1999《污水排入城市下水道水质标准》,小型垃圾转运站排放的污染物中,以COD负荷最高,其次是BOD5。大量的有机物排入城市污水厂,对污水厂的正常运行造成冲击,如果直接排入水体,更加速了水体的污染,因此,常州市城市排水系统优化改造及垃圾转运站的截污、治理势在必行。

| Abstract: | The output and properties of leachate were monitored and analyzed from small-scale MSW transfer stations of two cities in China.The results showed that the amounts of MSW small-scale transfer stations in China were large and its distribution was very intensive;mixed sewage generated from Shenzhen MSW transfer station has discharged into urban sewage pipe network,while in Changzhou,50% of the mixed sewage generated from MSW transfer station has discharged directly into the river.In addition to mercury,other ... |
