| 摘 要： | 某市污水处理厂二期工程Et处理污水能力为7万m^3。根据一期工程的NH3-N、COD平均值随月份的变化曲线确定了二期的进出水水质。根据BOD5／CODer、BOD5／TKN和BOD5/TP，确定了二期污水生物处理的可行性。在方案对比后，确定立式表曝氧化沟工艺为污水二级处理的技术方案，纤维转盘滤池工艺为深度污水处理工艺。论文提出了某市污水处理厂二期工程的污水处理工艺，可以为类似工程提供借鉴。

| Abstract: | Wastewater treatment capacity of the second phase project of an urban wastewater treatment plant is 70,000 m3/d. According to monthly change of average value of NH3-N and COD of the first phase project, quality of influent and effluent water of the second phase project was determined. According to BODs/CODcr, BODJTKN and BODs/TP, the feasibility of sewage biological treatment of the second phase project was confirmed. After comparing various technologies, the vertical aeration oxidation ditch process for the second phase project was determined; fiber disk filter process was used in the deep treatment. The sewage treatment techniques in the article can offer experiences for similar projects. |
