摘要：

使用MBR工艺处理石化废水,需要针对石化废水的特点,并结合工艺运行的实际情况,采取相应的运行管理措施。通过对产水周期、产水量、曝气量、污泥浓度等运行参数的调整,提高了工艺系统处理能力,降低了处理成本,产水水质完全符合排放标准的要求。在调整运行参数的同时,采取措施控制膜污染速率,确保了工艺系统的运行安全和稳定。

Abstract:

Using membrane bioreactor process for treating the wastewater from petrochemical industry,it is necessary to know the characteristics of the wastewater,combining with the actual situation of technological operation,and take corresponding management measures.Based on the adjustment of operational parameters,such as cycle and quantity of effluent,aeration and sludge concentration,the treatment capacity of technological systems has been improved,cost has been reduced,and effluent water quality has met the requirement of discharge standard.In the meanwhile,some measures have to be taken,so as to control the rate of membrane pollution,and ensure the safety and stability of the MBR system.

Key words: membrane bioreactor, wastewater from petrochemical industry, control of membrane pollution
