高浓度污水水质平稳是炼油厂实现污水稳定达标排放的关键。通过对南方某大型炼油厂高浓度污水处理系统各工段冲击状态的进水、出水水质进行全面分析，发现碱渣湿式氧化工段出水中酚和硫化物、污水除油工段出水含油均超过设计要求，生化过程溶氧偏低，导致高浓度污水处理系统冲击状态水质较差。针对发现的问题，提出了相应的解决方案。

Keeping the stable quality of high concentrated wastewater is the key to reach the dis-charge standards for refinery wastewater. The operation results of high pollutant wastewater treatment system indicate that the wastewater shock has a severe influence on alkaline residue wet-air oxidation process and oil-removing process,resulting in more phenol,sulfide and oil than design requirement in treated wastewater and low dissolved oxygen in bio-chemical process under the wastewater shock condi-tions. It becomes the bottleneck for effluent to meet the discharge standards. Solutions were put for-ward to solve the problems.
