摘　　要：为研究规模化养猪场污水的提标改造技术,依托江西某规模化养猪场原有的上流式厌氧污泥床(UASB)工艺,采用厌氧-两级A/O-MBR-絮凝沉淀相结合的主体工艺,通过工程改造后的运行数据,分析改造工艺对实际猪场污水的处理效果。对改造的工艺流程、设备规格、污水处理效果及运行成本进行了介绍。运行结果表明,废水经该工艺处理后,出水水质达到《鄱阳湖生态经济区水污染物排放标准》(DB 36/852-2015)中高效集约发展区的排放限值要求;污水处理设施运行费(含:电费、药剂费和人工费)为3.34元/t,该改造工艺具有较好的应用价值。本研究为高浓度污染物的猪场废水处理达标排放以及设施提标改造提供技术参考。The wastewater treatment process of anaerobic-two-stage A/O – MBR-chemical flocculation was used for upgrading the existing wastewater treatment station in a large-scale pig farm in Jiangxi province. The technological process, equipment specification, treatment efficiency,and operation costs were introduced. The running results showed that the effluent quality meets the limit of maximum daily average emission concentration in the "Wastewater discharge standard of Poyang Lake eco-economic district in Jiangxi Province"(DB 36/852-2015). The operation cost was estimated at 3.34 yuan/t, including the electricity, chemicals, and labor costs. The upgrading wastewater treatment process can be conducted to actual application in swine wastewater treatment.
