【 摘 要 】

The wastewater was treated by hydrolysis acidification and contact oxidation according to the characteristics of wastewater which produced by cigarette production process. The wastewater produced by cigarette manufacturing department was separate pretreatment using coagulation-air flotation. The results indicate that the coagulation-air floatation process for white glue wastewater pretreatment is feasible and effective. The white glue wastewater was prone to bubbles and had a large influence on the contact oxidation. The main process of Hydrolytic acidification and contact oxidation was running in good condition after white glue wastewater pre-treatment. The removal rate of COD was over 85%. The quality of effluent water is better than integrated wastewater discharge standard (GB8978-1996).
