生物膜活性炭法处理含油污水

TREATMENT OF OILY WASTE WATER BY BIOLOGICAL FILM-ACTIVATED CARBON

本文介绍了广州石化总厂利用生物膜活性炭处理含油污水的技术和成果,讨论了生物膜活性炭的吸附机理和处理效果.研究表明,该流程是通过活性炭吸附、生物吸附和生物降解的共同作用,使处理后的污水中的污染物排放量减少,它不但提高了处理效率而且还延长了活性炭的使用周期,适用于污水的三级处理.

The technology of treating oily waste water by biological film-activated carbon and its application in Guangzhou General Petrochemical Works were presented in this paper. The adsorption mechanism and effects of treatment by adsorption of biological activated carbon were discussed. Results of investigation showed that this technology operates through the synergism of activated carbon adsorption, biological adsorption and biodegradation. The discharged amount of pollutant in treated waste water is reduced. It not only enhances the efficiency of treatment, but also extends the operation period of the activated carbon. This method is applicable to the three-stage treatment of waste water.
