【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。
[Abstract]:Fenton oxidation method, wet oxidation method and microwave catalytic oxidation method were used to treat the refinery alkali slag wastewater with a COD value of 15 000 mg / L ~ (2) (mass concentration 2 100 mg/L). The experimental results showed that the wastewater was treated by Fenton oxidation method, wet oxidation method and microwave catalytic oxidation method. On the basis of optimizing process parameters, these three advanced oxidation methods can significantly reduce the content of COD and sulfides in the wastewater, and meet the technical requirements of COD 鈮，
