UNITANK王 乐, 缪焕权, 周业勤(佛山市新之源污水处理有限责任公司,广东佛山528000)   : 大沥污水处理厂一期工程采用增设厌氧池的UNITANK工艺,经过几个月的调试运行,出水水质达到设计要求,部分指标优于设计标准。由于在UNITANK工艺前端增设了厌氧池,有效提高了UNITANK工艺的脱氮除磷效果。  : 污水处理厂; UNITANK工艺; 调试运行; 脱氮除磷:X703.1  :C  :1000-4602(2008)02-0092-03CommissioningandOperationofUNITANKProcessinDaliWastewaterTreatmentPlantWANGLe, MIAOHuan-quan, ZHOUYe-qin(FoshanXinzhiyuanWastewaterTreatmentCo.Ltd.,Foshan528000,China)  Abstract: UNITANKprocesswasusedinthefirststageofDaliWastewaterTreatmentPlant.Theeffluentqualityreachesthedesignrequirementsafterseveralmonthsofcommissioningandoperation,andsomeofthewaterqualityindexaresuperiortothedesignstandard.Theanaerobictankwhichissetbe-foretheUNITANKprocessimprovesnitrogenandphosphorusremovalefficiencyefficiently.
