焦化废水具有可生化性差、有机物浓度高、组分复杂且有毒性等特点,经过常规生化处理后,COD和氨氮仍然不能满足排放要求.电化学氧化法具有降解效率高、停留时间短、占地面积小、无二次污染等特点,可以用于焦化废水的深度处理以解决这一问题.阳极是影响电化学氧化法的重要因素,文章介绍了BDD电极、DSA电极、三维电极用于焦化废水深度处理的研究现状并进行了展望.%Coking wastewater is characterized by poor biodegradability ,high concentration of organic substances , complicated composition and high toxicity. After being treated by regular biochemical treatment ,its COD and am-monia nitrogen still could not meet the discharge requirements. Since electrochemical oxidation method is charac-terized by high degradation rate,short residence time,less site area,free from secondary pollution,etc,it can be used for solving the problems in the advanced treatment of coking wastewater. It is well known that anodes are the impor-tant factor affecting electrochemical oxidation method. Therefore,in this paper,the current research status and prospect of three kinds of anodes:namely boron-doped diamond electrodes,dimensionally stable anode electrodes and three-dimensional electrodes applied to the advanced treatment of coking wastewater are introduced.
