常州某垃圾填埋场渗滤液处理工程实例

Engineering Example of a Landfill Leachate Treatment Project in Changzhou

常州某渗滤液处理厂采用A/O+MBR+RO工艺组合处理来自旁边大型生活垃圾填埋场的渗滤液,该填埋场根据其年限为成熟期填埋场,渗滤液具有高氨氮、低碳氮比、低COD等特点,可生化性较差。渗滤液处理厂日处理量60~126吨,执行《生活垃圾填埋污染控制标准》GB16889—2008标准,通过5年处理厂的稳定出水以及连续两个月数据检测分析,证明此工艺组合对于高氨氮、低B/C比的渗滤液处理效果好,处理渗滤液中的氨氮、总磷、COD等各种污染物结果稳定。

A leachate treatment plant in Changzhou adopts the combination of A/O+MBR+RO process to treat leachate from a large domestic waste landfill nearby.The landfill is a mature landfill according to its age.The leachate has the characteristics of high ammonia nitrogen ratio,low carbon nitrogen ratio and low COD etc.as well as poor biodegradability.The leachate treatment plant has a daily treatment capacity of 60~126 tons,and implements the"Standard for the Control of Domestic Waste Landfill Pollution Control"GB16889-2008.After 5 years of stable effluent from the treatment plant and two consecutive months of data detection and analysis,it shows that this process combination has a good effect on the leachate treatment with high ammonia nitrogen ration and low B/C ratio,and the treatment of various pollutants such as ammonia nitrogen,total phosphorus and COD in the leachate is stable.
