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苇浆造纸中段废水,对整个工艺及调试运行过程进行了详细介绍。实际运行结果表明,该工艺设计合理,运行稳定可靠,总排放口出水CODCr≤150mg/L、SS≤50mg/L、BOD5≤30mg/L,出水水质可达到《造纸工业水污染物排放标准》(GB3544—2008)的要求。The oxidation ditch process improved by low pressure jet aeration system and its commissioning running of the treatment of the effluent from washing and bleaching stages in a reed pulp mill was introduced in detail.The practical result showed that the process design is reasonable and reliable,and the discharged effluent quality can meet the ＂the paper industry water pollution discharge standard＂（GB3544 —2008）requirements with CODCr ≤150 mg/L,SS≤50 mg/L,BOD5≤ 30 mg/L.
