基于快速城市化的分散式污水处理模式研究

择运行费用较低的生物氧化接触法或生物曝气滤池处理技术。(4)在适宜于分散处理工艺模式选择的基础上，得出用户自助模式可适用宾馆、写字楼、商业会所及高校污水处理系统的运营管理；建设．拥有．运营模式(Build．Owning．Operation，简称BOO)适用于中、小型居民社区污水处理及回用系统的运营管理；建设．经营．转让模式(Build．Operate．Transfer，简称BOT模式)适用于大型居民社区、经济开发区的污水处理系统的运营管理。(5)提出了加快制定污水分散处理技术体系、促进污水分散处理的优惠政策、调整污水处理收费政策及在线监测等促进污水分散处理模式应用的对策建议。关键词：城市化；污水分散处理；中水回用THERESEACHONTHEMODELOFTHEDECENTRALIZED1l—乙～STEⅥ礁TERTREAMENTINRAlPIDLYURBANIZATIONAbstractCentralizedsewagetreatmentintheurbansewagetreatmentisthemainform，havegoodeffects，manageable，and”scaleeffect”ofurbanwateretc，whichplaysanimportantroleintheprotectionoftheenvironment．However,duetothesewagetreatmentfacilitiesforcentraltreatmentofconstructionfunds，longperiod，theurbansewagetreatmentlag，theurbansewagedischargeareaastherapidexpansionofurbanwaterenvironmentofthepressureofincreasingimportamarea．Distributedsewagedisposalmode，canachievethesewagetreatmentfacilitiesconstruction，nearwithflexible，lessinvestment，Canbeusedasthecentraltreatmentmodeofbeneficialsupplement，andhasimportantsignificance．Basedonurbandistributedsewagetreatmentmodeastheresearchobject，thefirstthroughtheconcentrationanddispersioncharacteristicsofwastewaterandrestrictionfactoranalysismodelofsewageprocessingarea,scatteredjudgment．Secondly,inthewastewatertreatmenttechnologyscatteredonthebasisofanalysisoftheregionalcharacteristics，accordingtodifferentconstructsthedischargestandardsandsewageprocessingmodedispersionrecycledscatteredprocessingmode．Finally,thesewagetreatmentconditionalityscattered，formulatethesewageprocessingoperationmanagementmodeanddispersion，someconclusions：(1)Intheurbanizationprocess，sewagedisposalmodeshouldfocusonhandling，processing，scatteredfromthewholerealizationofurbansewagetreatmentofcentralizedanddecentralizedeffectivecombination，improvetheurbansewagetreatment，improvingtheurbanwaterenvironmentofthepressure．(2)Sewageprocessingareascatteredjudgementisformulatedaccordingtothepatternofwastewatertreatmenttechnology．Sewagetreatmentmodeapplicationinscatteredinthefollowingareas：concentrations
