摘要：

山东济南市某城市生活垃圾焚烧发电厂产生的渗滤液COD和NH₃-N浓度高,且其处理后尾水需直排入海。针对该水质特点及排海要求,采用预处理/生化处理/深度处理三段式多级串联强化生物处理组合工艺进行处理。工程运行实践表明,多级串联强化生物处理法对垃圾渗滤液的处理效果良好,COD、NH₃-N去除率极高,出水水质高于《城镇污水处理厂污染物排放标准》(GB 18918-2002)中的一级A标准,可直排入海。

Abstract:

The COD,NH₃-N of landfill leachate produced from a city domestic garbage incineration power plant in Jinan,Shandong Province was pretty high. And the treated tail water needs to be discharged into the sea directly. The combined process,pretreatment/biological treatment/advanced treatment three-segment multistage series enhanced biological treatment has been used for this purpose. The operation results show that the series enhanced biological treatment has good treatment effect on landfill leachate. Its COD and NH₃-N removing rates are very high. Its effluent water quality is higher than that of Class A of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants(GB 18918-2002),and the effluent can be discharged into the sea directly.

Key words: landfill leachate, enhanced biological treatment, directly discharging into the sea
