摘　　要：臭氧催化氧化因O_(3)分子的强氧化性和催化协同产生羟基自由基的二次氧化性,使其广泛应用于难降解工业废水处理工艺中。回顾了臭氧催化氧化在工业废水预处理以及深度处理单元中的研究应用,指出了现阶段臭氧催化氧化中存在的臭氧利用率低、生产成本高、金属离子溶出等问题,对提高臭氧利用率、催化剂评价体系和结合反应机理探索不同类型工业废水高效催化剂等三方面提出了展望。Catalysis ozonation is widely used in the treatment process of refractory industrial wastewater due to the high oxidizability of O_(3) and the secondary oxidizability of hydroxyl radicals produced by the catalyst.The research and application of catalysis ozonation in industrial wastewater pretreatment and advanced treatment units is reviewed in this article.And the problems of low ozone utilization,high production costs,and metal ion elution in the current stage of catalysis ozonation are pointed out.The future work could focus on improving ozone utilization,the catalyst evaluation system and combining mechanism to explore suitable catalysts for different types of industrial wastewater.
