摘　　要：从污水处理站提标改造和扩建工程的主要因素、处理规模、处理工艺、投资估算等方面进行论证,分析了水质及原有设施的情况,介绍了工艺选择的依据,并详述了主要构筑物设计,对工程方案的技术可靠性、经济合理性、实施可行性进行了分析和论证。运行结果表明,采用“厌氧+好氧生化(好氧活性污泥+生物膜)+物化”法后,排放废水中COD的平均去除率达80%以上,出水CODCr≤200 mg/L,符合GB 4287—2012《纺织染整工业水污染物排放标准》的间接排放要求。The main factors,treatment scale,treatment process,investment capital of the sewage treat⁃ment station upgrading and expansion project are demonstrated.The water quality and the original facili⁃ties are analyzed.The basis of process selection is expounded.The main structures are detailed.And the technical reliability,economic rationality and implementation feasibility of the project plan are ana⁃lyzed and demonstrated.The operation results show that the average removal rate of COD is over 80%and the effluent CODCr is less than or equal to 200 mg/L after adopting the"anaerobic+aerobic biochem⁃ical(aerobic activated sludge+biofilm)+physicochemical"method,which meets the indirect discharge requirements of GB 4287—2012 discharge standard of water pollutants for textile dyeing and finishing in⁃dustry.
