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。
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 en-hanced biological treatment has been used for this purpose. The operation results show that the series enhanced bio-logical 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.
