摘　　要：四川省内江市某工业园区的污水处理厂项目,面对水质水量剧烈波动和环境恶化的挑战,采用“A^(2)O+MBR+NF”工艺组合,分两期建设,近期规模1.25万m^(3)/d。项目进水以工业污水为主,出水依照地表水准Ⅲ类标准设计。自2020年投产以来,运行稳定,出水水质显著优于设计标准,有效提升了区域环境质量,为园区的可持续发展提供了有力支持。The sewage treatment plant project in an industrial park in Neijiang City,Sichuan Province,faces challenges from severe fluctuations in water quality and quantity,as well as environmental degradation.To address these issues,it utilizes the"A^(2)O+MBR+NF"process combination and is being constructed in two phases,with a recent scale of 12,500 m^(3)/d.The inflow is primarily industrial wastewater,while the outflow is designed to meet Surface Water Class Ⅲ standards.Since its commissio-ning in 2020,the plant has operated stably,with effluent quality significantly exceeding design stand-ards,effectively improving the regional environmental quality and providing strong support for the sustain-able development of the park.
