开封市西区污水处理厂升级改造工程建设和运行

摘要

开封市西区污水处理厂在一期“三沟式氧化沟”工艺基础上增加了后续深度处理工艺,使二期改造工程达到了提标升级要求。实践表明：采取“三沟式氧化沟+絮凝沉淀+纤维转盘滤池+二氧化氯消毒”工艺可保证污水厂的出水水质稳定达一级A排放标准,吨水能耗比改造前仅增加了0．04kWh,电耗和药剂费吨水成本增加在0．1元左右,该改造工艺可在采用氧化沟工艺的污水处理厂的提标升级改造中推广应用；总结的改造技术及调试和运行经验对提标升级改造工程的实施具有重要的借鉴意义。%The second phase of upgrading and reformation project of Kaifeng West City Wastewater Treatment Plant reached requirements when the subsequent depth treatment process was added to the triple oxidation ditch process. The practical transformation technology and experience of commission and operation had important reference to implementation of upgrading and reformation project.
