Abstract
Catalytic wet air oxidation (CWAO) technology has the characteristics of wide application range, high organic matter removal rate, low secondary pollution and high efficiency, etc., and it has significant effects on the treatment of difficult biodegradable organic waste-water. According to the homogeneity of the phases of the catalytic reaction system, the catalytic reactions can be divided into two categories: homogeneous catalysis and heterogeneous catalysis. The reported catalysts or their active components mainly include four categories: metal salts, metals/supports, oxides/supports, and composite oxides/supports.
