Abstract:

The effects of some methods for treating reverse osmosis concentrated water of oil refining wastewater have been investigated. The results show that compared with Fenton process and iron carbon micro-electrolysis process, ultrasonic-assisted Fenton process and adsorption-bio-regeneration process have better degradation effect on reverse osmosis concentrated water of oil refining wastewater. Their COD removing rates can be as high as 80%, effluent COD are all less than 60 mg/L, and effluent oil quality mass concentrations are all less than 1.0 mg/L. However, from the view of process feasibility, adsorption-bio-regeneration process has the advantages of low-cost, no secondary pollution, and more suitable for practical applications.

摘要：

探索了几种处理技术对炼油废水反渗透浓水的处理效果。结果表明，相比于Fenton法和铁炭微电解法，超声波辅助Fenton法以及吸附-生物再生法对炼油废水反渗透浓水的降解效果较好，COD去除率可达到80%，出水COD均低于60 mg/L，且出水油质量浓度均小于1.0 mg/L。从工艺可行性来看，吸附-生物再生法具有成本低、无二次污染的优点，更适合于实际应用。
