生物吸附+A/O+混凝沉淀处理精制棉生产废水

Treatment of Refined Cotton Production Wastewater by Combined Process of Biological Adsorption,A/O,Coagulation Sedimentation and Filter

介绍了生物吸附+A/O+混凝沉淀+过滤处理精制棉生产废水的工程实例。运行结果表明,该工艺处理效果稳定,出水COD、BOD5、SS、色度的平均浓度分别为87 mg/L、14.3 mg/L、46.2 mg/L、42.6倍,出水水质达到《污水综合排放标准》(GB 8978—1996)的一级标准。

The project case of using the combined process of biological adsorption, A/O, coagula- tion sedimentation and filter for refined cotton production wastewater treatment was introduced. The oper- ational results proved that the combined process had stable treatment efficiency and the average co trations of COD, BODs, SS and color in the effluent were 87 rag/L, 14.3 mg/L, 46.2 mg/L and times, respectively. All quality indicators of the effluent could meet the first class criteria specified Integrated Wastewater Discharge Standard （ GB 8978 - 1996 ）.
