The use of catalytic wet air oxidation (CWAO) technology to treat organic waste-water that is difficult to biodegrade had a significant effect. The following 12 types of waste-water have achieved good results with the CWAO method. The 12 types of waste-water include: papermaking waste-water, dye waste-water, pesticide waste-water, perfume waste-water, phenol waste-water, carbon-containing waste-water, ethanol waste-water, petrochemical company alkali residue waste-water, and oil extraction waste-water, ammonia-containing coking waste-water and pesticide waste-water, cleaning workshop emulsified waste-water and desizing waste-water. A typical homogeneous catalytic wet oxidation system includes 5 processes: Ciba Geigy, Bayer Loprox, WPO, Orcan, and IT Enviroscience. Heterogeneous catalysts lose their activity due to the low pH of the reaction system and the accumulation of activated carbon.
