摘　　要：焦化废水是一种极难生化降解的有毒有害工业废水,具有可生化性极差,高氨氮,污染物成分复杂,毒性强等特点,常规的生化处理无法满足焦化废水的排放标准。电化学作为新型的绿色环保处理技术,具有降解效率高,无二次污染,灵活性高,易于控制等优点。阐述了电化学技术在焦化废水深度处理中的广泛应用,着重介绍了电化学处理的机理,分析了电催化过程中气泡和电极材料对降解效率的影响,总结了在电芬顿应用中提高自由基效率的方法,并结合近年来电化学处理技术的前沿研究提出了展望。Coking wastewater is a kind of toxic and hazardous industrial wastewater which is extremely difficult to be biochemically degraded, featuring very poor biodegradability, high ammonia nitrogen, complex pollutant composition and high toxicity. Because of its complex and high concentration of organic components, the conventional biochemical treatment cannot meet the discharge standard of coking wastewater. Electrochemistry, as a new green environment treatment technology, has the advantages of high degradation efficiency, no secondary pollution, high flexibility and easy control. This paper reviews the extensive application of electrochemical technology in the advanced treatment of coking wastewater, introduces the mechanism of electrochemical treatment, and analyzes the effects of bubbles and electrode materials on degradation efficiency in the electrocatalytic process, summarizes the methods to improve the efficiency of free radicals in electro-Fenton application, and presents an outlook in combination with the frontier research on electrochemical treatment technology in recent years.
