摘要:

介绍了金属氧化物类负载型催化剂在非均相催化臭氧氧化技术降解废水有机污染物的反应机理和研究现状,并对反应过程中的参数和影响因素进行归纳总结,得出金属氧化物类催化剂往往通过添加其他金属或氧化物协同处理有机废水。Fe及其氧化物有利于催化剂的回收和循环利用,Ce及其氧化物可提供丰富的酸碱点位,Mn及其氧化物可提供多变的晶体结构,Cu及其氧化物可提供活性反应中心。针对现有催化剂使用寿命不佳、活性组分易溶出、环境经济性不理想等问题,指出未来应加快、加深催化臭氧氧化反应机理的研究,同时在优化反应参数的基础上,针对部分重点行业,建立可复制、易于操作的处理模型并推广应用。

Abstract:

The reaction mechanism and research status of heterogeneous catalytic ozonation of organic pollutants in wastewater with metal oxides and supported catalysts were introduced,the parameters and influencing factors in the reaction process were summarized,and it was concluded that metal oxides were always used to treat organic wastewater by adding other metals or oxides.Fe and its oxides were beneficial to the recovery and recycling of catalysts,Ce and its oxides could provide rich acid-base sites,Mn and its oxides could provide variable crystal structures,Cu and its oxides could provide active reaction center.In view of the problems such as poor service life of existing catalysts,easy dissolution of active components and unsatisfactory environmental economy,it was pointed out that the research on the mechanism of catalytic ozonation should be speeded up and deepened in the future.At the same time,on the basis of optimizing the reaction parameters,a replicable and easy-to-operate treatment model was established for some key industries and popularized.
