Landfill leachate treatment design of Yanqun Refuse Landfill Yard in Xuzhou City

徐州市雁群卫生填埋场渗滤液治理工程针对城市生活垃圾场渗滤液可生化性差、氨氮含量高等特点,采用了吹脱—混凝沉淀—A2/O的处理工艺。介绍了工艺的设计参数、特点、运行情况和技术经济参数,结果表明,该工艺出水水质达到了《生活垃圾填埋污染控制标准》(GB16889—1997)的二级标准。

This is an urban domestic refuse disposal facility, the leachate has high ammonia nitrogen content and very poor biological tractability. Air stripping-coagulating sedimentation- A^2/O processes are adopted to treat it. In this paper the parameters in process design, features, operating status and techno-economical indexes of this facility are presented. The practice results show that the effluent is quit enough to meet the requirement of class Ⅱ in the Standard for pollution control on the landfill site for domestic waste （GB 16889--1997）.
