棉蛋白生产废水处理工程实例

摘要

河北某棉蛋白加工公司采用酵母菌反应池-UASB-SBR-MBR工艺来处理棉蛋白生产废水,设计处理量为50 m3/d.运行实践表明,该工艺合理可行,工程系统运行稳定可靠,出水达到《城市污水再生利用城市杂用水水质标准》(GB/T 18920—2002)中的城市绿化用水要求.%In a cotton protein processing company in Hebei Province,China,the process of yeast group reaction tank-UASB-SBR-MBR has been used for the wastewater treatment whose designed treatment capacity is 50 m3/d. Theoperation practice shows that the process is feasible and the system runs stably and reliably. The effluent meets therequirements for urban green water specified in the Water Quality Standard for Urban Miscell-aneous Water-UrbanSewage Regeneration and Utilization(GB/T 18920—2002).
