摘　　要：针对生猪养殖废水高COD、高氨氮、高SS、可生化性较好的特点,采用“固液分离-气浮系统-UASB-二级A/O工艺”处理该废水。污水处理系统建成后,经过调试运行稳定,处理后的出水各项指标均达到《农田灌溉水质标准》(GB 5084—2005)中旱作(作物种类)排放标准,最终污水回用于当地农业。Aiming at the characteristics of high COD,high ammonia nitrogen,high SS and good biodegradability of pig breeding wastewater,the project adopts"solid-liquid separation-air flotation system-uasb-secondary A/O process"to treat the wastewater.After the completion of the sewage treatment system,it has been debugged and operated stably,all indicators of the treated effluent meet the discharge standard of dry farming(crop species)in the standard for irrigation water quality of farmland(GB 5084—2005),and the final sewage is reused for local agriculture.
