摘　　要：针对垃圾渗滤液处理难度大、费用高的问题并考虑到村镇污水的特点及其有限的处理条件,本试验采用了占地面积小、操作简单、操作和运行费用低的生物转盘工艺处理一定比例的垃圾渗滤液与村镇污水的混合液。试验结果表明:在HRT为10h,转盘转速为2r/min的最优工况下,当垃圾渗滤液与村镇污水以1∶600以下的体积比混合时,出水水质满足《城镇污水处理厂污染物排放标准》(GB1891822002)一级A标准,结合垃圾渗滤液的日处理量问题,得出此试验条件下,掺加垃圾渗滤液的最佳混合比例为1∶600,为有效解决村镇污水与村镇垃圾填埋场渗滤液的处理问题提供借鉴和参考,对进一步达到"村容整洁"这个社会主义新农村建设的目标具有促进作用。As for the problem of huge investment and difficulty of treating landfill leachate,considering the characteristics of rural sewage and its limited treatment,the experiment adopts rotating biological contactor to treat the mixture of landfill leachate and municipal sewage.The test results show that under the condition of 11 h HRT,2r/min,when the mixing volume ratio,of landfill leachate and municipal sewage,is less than 1∶600,the effluent concentration can achieve the first standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant（GB1891822002）.By considering comprehensively effluent quality and treatment amount of landfill leachate by the sewage plants in practice,we can draw a conclusion that the 1∶600is the most suitable one of mixing volume ratio of landfill leachate and municipal sewage,which can provide a reference for the effective treatment of rural sewage and landfill leachate,and play apromoting role in village neatness,which is required by the construction of new socialist countryside.
