摘　　要：以某造纸厂废水处理工程为例，介绍了气浮．水解酸化．生物接触氧化-气浮工艺在造纸废水处理中的应用。厂内造纸废水量为750m3／d，COD为600~2400mg／L，BOD5为125~585mg／L，SS质量浓度为650~2400mg／L，色度为450~900倍，经生化处理后，出水COD、BOD，分别为79．5mg／L、20-3mg／L，出水SS质量浓度为29mg／L，色度为48倍。出水可迭GB3544--2008排放要求。废水处理成本为0．60元／m3，具有良好的经济效益和环境效益。The application of air flotation-hydrolysis acidification-biological contact oxidation-air flotation process to treat the papermaking wastewater was introduced .The results showed that when the influent flux, COD, BOD5 and SS ofpapermaking wastewater were 750 m3/d, 600~2 400 mg/L, 125~ 585 and 650~2 400 mg/L, respectively, the average effluent COD, BOD5 and SS were 79.5, 20.3 and 29 mg/L, respectively. The chroma of effluent was 48, which met the discharge standard ofwater pollutants for pulp and paper industry （GB3544--2008）. The treatment cost was about 0.60 yuan/m3, which has good economic and environment benefits.
