摘　　要：山东省某县经济开发区污水处理厂总规模为4.5×10^(4 )m^(3)/d,一期采用A~2O生化池+气浮池+纤维束滤池工艺,二期采用调节池-涡凹气浮池-水解酸化池-A~2O生化池-二沉池-高效沉淀池—臭氧接触池-V型砂滤池工艺。现状一期和二期工程出水水质均能稳定达到《城镇污水处理厂污染物排放标准》(GB 18918-2002)的一级A标准。因服务范围内多家企业有再生水使用需求,通过改造二期工程生化系统及深度处理系统,使出水水质提标至地表准Ⅳ类水质后,再与一期出水勾兑进入再生水系统。二期改造采用Bardenpho及臭氧催化氧化工艺,再生水系统采用双膜法(UF+RO)进一步去除盐分。2022年通水以来,实际再生水量为1 530 m^(3)/d,再生水费用为2.0元/m^(3)。整个系统运行安全稳定,出水满足企业用水要求,效果良好。The total capacity of the wastewater treatment plant(WWTP)in a county in Shandong Province is 4.5×10^(4) m^(3)/d.The first phase adopts A2O biochemical tank,air floating tank,and fiber buddle filter process,while phaseⅡadopts regulating tank,vortex cavity floating tank,hydrolytic tank,A2O biochemical tank,secondary sedimentation tank,high-efficiency sedimentation tank,ozone contact tank and V-shaped sand filter.The effluent quality of the first and second phase of the project can stably meet the first-level A criteria of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).Due to the demand for reclaimed water by multiple enterprises in the service scope,by renovating the biochemical system and advanced treatment system in phaseⅡproject,the effluent quality is upgraded to quasi-Ⅳof Environmental Quality Standards for Surface Water(GB 3838-2002),and then blended with the first phase effluent to enter the reclaimed water system.The renovated phaseⅡproject adopts Bardenpho and ozone catalytic oxidation technology,while the reclaimed water system uses the UF and RO membrane method to further remove salt.Since operation in 2022,the actual reclaimed water volume is 1530 m^(3)/d,and the cost of reclaimed water is 2.0 yuan/m^(3).The system operates safely and stably,and the effluent meets the water requirements of enterprises with good effect.
