Abstract

The common treatment methods for industrial biodegradable industrial waste-water are physical, chemical and biological methods, but the conventional methods have complicated and inefficient treatment processes. Wet air Oxidation (WAO) technology can effectively treat industrial biodegradable industrial waste-water. WAO has achieved good results in the treatment of pesticide waste-water, dye waste-water, activated sludge and phenol-containing waste-water. The CODCr removal rate of waste-water reaches 72.3 %∼95.3 %. In order to further improve the application effect of WAO technology, three improvement approaches have been developed: Catalytic Wet Air Oxidation, Catalytic Wet Supercritical Oxidation, and Catalytic Wet Peroxide Oxidation.
