曹大伟1, 李先宁1, 李孝安2, 花蓉蓉3, 陶雪江2(1.东南大学能源与环境学院,江苏南京210096;2.杭州市城市规划设计研究院,浙江杭州310012;3.同济大学城市污染控制国家工程研究中心,上海200092) : 采用地埋式一体化生物滤池工艺处理农村生活污水。该工艺通过设置前置缺氧池进行反硝化脱氮,通过拔风和溅水来强化充氧效果,实现了碳氧化及硝化。中试结果表明,该工艺对COD的平均去除率达63.1%,对NH+4-N的去除率为92.2%,对TN的去除率为68.6%,对TP的去除率为47.5%,出水水质达到了《城镇污水处理厂污染物排放标准》(GB18918—2002)的一级标准。该工艺具有节能、高效和简易的特点,适于在居住分散的农村地区推广。 :(863)(2002AA601012-1A) : 农村生活污水; 一体化生物滤池; 拔风溅水充氧; 脱氮; 低能耗:X703.1 :A :1000-4602(2008)01-0030-05BuriedIntegratedBiofilterProcessforTreatmentofRuralDomesticSewageCAODa-wei1, LIXian-ning1, LIXiao-an2, HUARong-rong3, TAOXue-jiang2(1.CollegeofEnergyandEnvironment,SoutheastUniversity,Nanjing210096,China;2.Hang-zhouCityPlanningandDesignResearchInstitute,Hangzhou310012,China;3.NationalEnginee-ringResearchCentreforUrbanPollutionControl,TongjiUniversity,Shanghai200092,China) Abstract: Theburiedintegratedbiofilterprocesswasusedtotreatruraldomesticsewage.Thecar-bonoxidationandnitrificationwerecarriedoutthroughdenitrificationinpre-anoxicpondandenhancedoxygenationbyventilatingandsplashing.ThepilottestresultsshowthattheaverageremovalratesofCOD,NH+4-N,TNandTPare63.1%,92.2%,68.6%and47.5%respectively.Theeffluentquali-tyachievesthefirstclasscriteriaspecifiedintheDischargeStandardofPollutantsforMunicipalWastewaterTreatmentPlant(GB18918-2002).Theprocesshascharacteristicsofenergy-saving,highefficiencyandsimpleoperation,thusitissuitabletobegeneralizedinruralareasinhabiteddispersedly.
