某石化企业污水处理工程设计案例

Design case of sewage treatment project of a petrochemical enterprise

以甘肃省某石化企业污水处理工程为研究对象,通过对污水厂水质进行分析,确定了隔油+气浮+水解酸化+A/O+曝气生物滤池的组合处理工艺,使系统可良好稳定运行,与(GB8978-1996)污水综合排放标准的二类污染物一级标准规定相符,实现了降低外排污染物碳总量的目标,具有良好的环境和经济效益。

Taking the sewage treatment project of a petrochemical enterprise in Gansu Province as the research object,the combined treatment process of oil separation+air flotation+hydrolytic acidification+A/O+biological aerated filter was determined through the analysis of the water quality of the sewage plant,so that the system can operate well and stably,which is consistent with the Class I standard of Class II pollutants in the Integrated Wastewater Discharge Standard(GB8978-1996),and the goal of reducing the total carbon content of discharged pollutants was achieved,It has good environmental and economic benefits.
