新疆生产建设兵团某工业园区废水处理厂设计

Process design of industrial park wastewater treatment plant in the Xinjiang Production and Construction Corps

新疆生产建设兵团某工业园区废水处理厂进水由生活污水和工业废水组成,出水水质要求达到《城镇污水处理厂污染物排放标准》一级A排放标准(GB 18918-2002)。工程废水处理主体工艺采用粗格栅及进水泵房-气浮沉淀池-水解酸化池-A^2/O反应池-MBR反应池对进厂废水进行处理,污泥处理采用污泥浓缩池-厢式隔膜压滤机工艺。一期建设规模为3万m^3/d。介绍了工程设计进出水水质指标的确定、主要构筑物的工艺设计参数以及工艺设计特点,并对运营后进出水水质进行了分析。

The wastewater from the project of industrial park wastewater treatment plant in the Xinjiang Production and Construction Corps is composed of domestic sewage and industrial wastewater,and the effluent quality is required to meet the first level A criteria specified in the Discharge standard of pollutants for municipal wastewater treatment plant（GB 18918-2002）.The wastewater combined process of coarse grid and water pumping stations,floatation sedimentation tank,hydrolysis acidification tank,A^2/O biochemical treatment and MBR reactor tank was designed.Combined sludge treatment process of sludge thickening tank and van membrane filter press was also adopted.The construction scale of the first phase is 3×10~4 m^3/d.The determination of design influent and effluent quality,design parameters and process characteristics of the main units were presented.
