摘要
采用水解酸化 SBR法 混凝沉淀复合工艺对城市垃圾渗滤液进行处理 ,确定水解酸化、SBR法和混凝的最佳运行参数。结果表明 ,当进水CODCr172 0mg L、NH3 N 12 7 6mg L时 ,通过该系统处理后 ,出水CODCr 148 4mg L、NH3 N 12 2mg L ,CODCr总去除率达到 91 2 % ,NH3 N去除率达 90 4% 。
Urban landfill leachates were treated by composite process of hydrolytic acidification-SBR-chemical coagulation and sedimentation,and the optimum processed conditions of the anoxic,SBR and coagulation were achieved.The result showed that the influent with COD_ Cr= 1 720 mg/L,NH_3-N= 127.6 mg/L were reduced to 148.4 mg/L and 12.2 mg/L respectively by this process.The removal rates of COD_ Cr and NH_3-N were 91.2% and 90.4%.This means that the best purification of organic and denitrification have been obtained,and this composite process is reliable and effective.
