- 摘要:
- 焦化废水是一种典型的高浓度有机工业废水,成分复杂,COD和氨氮浓度高,可生化性差,因此采用生物处理具有一定的局限性和难度。介绍了高级氧化技术(AOPs)处理焦化废水的研究进展,论述了AOPs中活性自由基的生成反应及处理焦化废水的作用机理,总结了各项技术在焦化废水处理中的应用现状和存在问题,并对AOPs耦合生物法处理焦化废水的研究方向进行了展望。
- Abstract:
- Coking wastewater presents a challenging scenario due to its characteristics of high concentration of refractory organic compound, complex composition, high concentration of COD and ammonia nitrogen, and poor biodegradability. Therefore, adopting biological treatment has certain limitations and difficulties. This paper delves into the research advancements of advanced oxidation processes (AOPs) for coking wastewater treatment. It explores the formation reaction of active free radicals and the mechanism of the treatment of coking wastewater in AOPs. Furthermore, it provides an overview of the current application status and associated challenges of various technologies utilized in coking wastewater treatment. Lastly, it outlines the research prospects for AOPs coupled with biological methods for the treatment of coking wastewater.
