东北地区城市净水厂耗水率现状调查与特征分析

给水排水Vol136No19201015东北地区城市净水厂耗水率现状调查与特征分析徐勇鹏1,2崔福义1,2姜金鑫1(1哈尔滨工业大学市政环境工程学院,哈尔滨150090;2哈尔滨工业大学城市水资源与水环境国家重点实验室,哈尔滨150090)摘要收集东北地区16座净水厂自用水消耗的资料,分析了水厂絮凝池、沉淀池等的排泥工况对水厂自用水耗水率及排泥水含固率的影响,以及水厂滤池反冲洗工况对自用水耗水率和反冲洗效果的影响。基于数据分析,对东北地区典型水厂自用水耗水率现状进行综合评价。调查结果表明,东北地区的水厂耗水率受水源水质、处理规模、处理工艺(新建或改造)和运行管理等条件的影响,自用水的节约潜力在于优化运行参数以适应季节变化和水量负荷的变化,以及改造滤池反冲洗方式。关键词净水厂自用水耗水率综合评价InvestigationofwaterconsumptionrateofwatertreatmentplantsintheNortheastChinaXuYongpeng1,2,CuiFuyi1,2,JiangJinxin1(1.MunicipalandEnvironmentalEngineeringCollege,HarbinInstituteofTechnology,Harbin150090,China;2.StateKeyLaboratoryofUrbanWaterResourceandEnvironment,HarbinInstituteofTechnology,Harbin150090,China)Abstract:Basedonthecollectionofselfwaterconsumptionof16watertreatmentplantsintheNortheastChina,thispaperstudiedtheimpactsofsludgedischargeoperationofflocculationtank,sedimentationtankonwatertreatmentplantsselfwaterconsumptionrateandsludgedrainagesolidcontent,andtheimpactsofback-washingoperationoffiltertankonselfwaterconsumptionandback-washingeffects.Basedondataanalysis,thecurrentselfwaterconsumptionrateoftypicalwatertreatmentplantintheNortheastChinawasevaluatedcomprehensively.Theresultsshowed:selfwaterconsumptionrateofwatertreatmentplantintheNortheastChinaisaffectedbywaterre-sourcewaterquality,waterproductionscale,treatingprocess(newlyconstructedorupgraded),andoperationandmanagement,andsoon;water-savingpotentialinselfwaterconsumptionliesinoperationparameteroptimization,sowhichcouldadopttothechangeofseasonsandwaterproduc-tionloa
