摘要:

催化臭氧氧化技术在处理难降解有机废水领域具有很大应用前景,催化剂是实现催化臭氧氧化的关键材料。本文综述了近年来在臭氧催化剂的制备及其应用方面的进展。臭氧催化剂主要是以Mn、Fe、Co等过渡金属氧化物为活性组分,负载型催化剂的载体主要有氧化铝、分子筛、活性炭等。与金属氧化物催化剂相比,负载型催化剂和碳质材料催化剂具有较好的催化效果。催化剂应用性能研究大多为实验室单一成分的有机废水,面向实际复杂工业废水研究开发优良的催化剂,并与具有高效臭氧传质性能的反应器相结合,是未来催化臭氧化技术研究开发的趋势。

Abstract:

Catalytic ozonation processes exhibit very good application potential in the treatment of recalcitrant organic pollutants. Catalysts play a key role in catalytic ozonation and thus have been investigated extensively. This paper describes the basic principles of both homogeneous and heterogeneous catalytic ozonation and then summarizes the preparation methods and properties of the catalysts. The main active compositions of ozonation catalysts involves the oxides of transitional metals such as Mn, Fe, Co, etc. The carrier of ozonation catalysts mainly involves porous Al2O3, molecular sieve and active carbon. Compared with metal oxide catalysts,supported catalysts and carbonaceous catalysts process higher efficiency. The performance test of ozonation catalysts are mainly based on simple model pollution substance. Highly efficient and stable catalysts towards real industrial wastewater treatment and their combination with advanced reactors which has high efficient ozone mass transfer will be the future development trends.

Key words: ozone, oxidation, catalyst, waste water
