Abstract:

The combination process of enhanced coagulation /multiply filters /UF/RO has been used for the treatment of oil-bearing wastewater that comes from the Wastewater Treatment Plant of Qilu Petrochemical Factory.The local experimental results show that the combination process has strong resistance capacity of impact loading.It runs steadily and the effluent water quality meets the recycle requirements of the circulating make-up water, when the turbidity, COD and oil concentration fluctuate greatly.

Key words: enhanced coagulation, filtration, ultra-filtration, reverse osmosis

摘要：

采用“强化混凝—多介质过滤—超滤—反渗透”处理工艺，对齐鲁石化污水处理厂出水进行深度处理试验研究，结果表明：在浊度、COD、油浓度波动较大的情况下，该处理工艺抗冲击负荷能力强、运行稳定，出水水质均符合循环冷却水系统补充水的要求。
