摘　　要：采用粉末活性炭活性污泥法(PACT)-湿式氧化再生(WAR)工艺处理某石化企业含油、含盐污水,处理规模均为500 m^(3)/h。针对装置运行过程中存在的问题进行了分析和优化,工程运行监测结果表明:该工艺脱氮除碳能力强且耐负荷冲击;含油污水处理后出水COD为36.8 mg/L,降低率为87.8%,氨氮平均质量浓度为0.3 mg/L,平均去除率为97.2%;含盐污水处理后出水COD为48.4 mg/L,降低率为89.9%,氨氮平均质量浓度为0.4 mg/L,平均去除率为98.0%,达到了装置出水水质指标要求;污水处理直接运行成本为3.07元m^(3),且实现了装置废气达标排放、生化剩余污泥近零排放,具有较好的示范作用。The process of powdered activated carbon treatment(PACT)+wet air regeneration(WAR)was used to treat the oily and salty waste water in a refinery with scales of 500 m^(3)/h.Based on the analysis and optimization of the existing problems in the operation of the unit,the operation monitoring results indicated that the process had strong nitrogen and carbon removal ability and could withstand load impact.The average effluent COD and ammonia nitrogen concentration of the oily waste water were 36.8 mg/L and 0.3 mg/L,respectively,and the average removal rates were 87.8%and 97.2%,respectively;the average effluent COD and ammonia nitrogen concentration of the salty waste water were 48.4 mg/L and 0.4 mg L,respectively,and the average removal rates were 89.9%and 98%,respectively,which could meet the requirements of the effluent quality index.The direct operating cost of the process was 3.07 yuan m^(3),the discharge of waste gas could meet the standard,and the discharge of biochemical surplus sludge was nearly zero,so the process had a good demonstration effect.
