流动床生物膜技术处理污水及资源化的研究

Study on Flowing Bed Biological Diaphragm Technique to Handle Waste Water and Its Resources

大庆市城市用水量和污水排放量不断增加,造成水资源紧缺,环境污染日益严重。大庆石化公司原污水处理系统出水不符合国家工业循环冷却水的水质标准,因此拟将原污水处理系统处理后的排放水经进一步处理后作为工业循环冷却水,实现污水资源化。为此,将原污水处理系统的二级出水经Bio-Sac反应池生物降解后,降解出水进入臭氧系统,进一步消解有机物,再进人原污水处理系统的三级处理装置过滤、吸附,最终出水可作为工业循环冷却水。

The city water consumption and waste water discharge rises continuously in Daqing city, which has resulted in shortage of water resources and severe environment pollution. The water from the original waste water treatment system in Daqing Petrol - Chemical Company did not comply with the quality standard of the national industrial circulating cooling water. The drainage from the original wastewater treatment system is planned to be the industrial circulating cooling water after further treatment to realize the resource of the wastewater. Therefore, the secondary drainage from the system is dissolved biologically through Bio - Sac reactive pool and the dissolved water enters into the ozone system for further dissolution of organic matter and then flows into the third - level treatment device of the original system for filtering and absorbing. The final water outgoing can be taken as the industrial circulating cooling water.
