摘　　要：针对COD值为15 000 mg/L、S^(2-)质量浓度为2 100 mg/L的炼油碱渣废水,分别应用芬顿氧化法、湿法氧化法以及微波催化氧化法对该废水进行了处理研究。实验结果显示,在优化工艺参数的基础上,这3种高级氧化方法均能够显著降低该种废水的COD及硫化物含量,满足COD值≤3 500 mg/L,ρ(S^(2-))≤100 mg/L的技术指标要求,而其中湿法氧化法对该种废水的处理效果最佳,可以将水中COD与ρ(S^(2-))分别降至555 mg/L及未检出。The treatment of refinery-sourced alkaline waste water with COD value of 15 000 mg/L and S〉 content of 2 100 mg/L by Fenton oxidation, wet air oxidation and microwave-assisted catalytic oxidation methods respectively is carried out.The experimental results show that these three advance oxidation methods all can significantly reduce contents of COD and sulfide in the waste water on the basis of optimizing the process parameters, and meet the technical requirements of COD ≤ 3 500 mg/L,ρ（S^2-） ≤100 mg/L.Among these three methods, the wet air oxidation has the best treatment effect as for such waste water, which can reduce contents of COD and ρ（S^2-） to 555 mg/L and absent respectively.
