摘　　要：采用供气式低压射流曝气系统改良型氧化沟工艺处理制浆造纸中段废水,对整个调试运行过程进行了介绍。实际运行结果表明,该工艺设计合理,运行稳定可靠,出水COD≤150mg/L、SS≤80 mg/L、BOD5≤80 mg/L,去除率均大于85%,出水水质达到了《造纸工业水污染物排放标准》(GB 3544—2001)。An improved oxidation ditch process using forced air supply low-pressure jet aeration system was used to treat middle-stage wastewater from pulping and papermaking. The whole commissioning of the process is introduced. The operation results indicated that the process has rational design and the system has stable and reliable operation. The effluent COD, SS and BOD5, are less than or equal to 150 mg/L, 80 mg/L and 80 mg/L respectively, and their removal rates are all higher than 85%. The effluent quality meets the Discharge Standard of Water Pollutants for Paper Industry （GB 3544 -2001 ）.
