Abstract:

The application of acid casein air flotation - hydrolytic acidification - contact oxidation process to the treatment of modified cellulose wastewater is presented. The operating results show that when the COD_Cr, BOD₅ and SS of the influent are 1 200, 500 and 600 mg/L respectively, the effluent of the system is good enough to meet the requirement of the First Class National Wastewater Integrated Discharge Standard (GB 8978 — 1996) .

Key words: modified cellulose wastewater, acid casein air flotation, contact oxidation

摘要：

介绍了酸析气浮—水解酸化—接触氧化工艺在处理改性纤维素废水中的应用。运行结果表明, 进水COD_Cr=1 200 mg/L、BOD₅=500 mg/L、SS=600 mg/L时, 出水达到GB 8978—1996一级排放标准。
