摘　　要：采用水解酸化/悬挂链移动曝气/超效浅层气浮/Fenton工艺处理制浆造纸中段废水,处理规模为25 000 m3/d。运行结果表明,当进水COD为2 000 mg/L、BOD5为700 mg/L、SS为500 mg/L时,经过该工艺处理后,出水COD≤90 mg/L、BOD5≤20 mg/L、SS≤30 mg/L,达到《制浆造纸工业水污染物排放标准》(GB 3544—2008),处理成本为1.85元/m3,其中药剂费为1.19元/m3。The combined process of hydrolysis acidification, Biolak, superefficient ion shallow air flotation and Fenton was used to treat pulping and papermaking middle-stage wastewater. The treatment capacity is 25 000 m3/d. The operation results show that when the influent COD, BOD5 and SS are 2 000 rag/L, 700 mg/L and 500 mg/L resepctively, the effluent COD, BOD5 and SS are equal to or less than 90 mg/L, 20 mg/L and 30 mg/L respectively, meeting Discharge Standard of Water Pollutants for Pulp and Paper Industry （ GB 3544 - 2008 ）. The treatment cost is 1.85 yuan/m3, in which the chemical cost is 1.19 yuan/m3.
