Wet Oxidation Technology Based on Organic Wastewater Treatment
Yongxun Zhang
Abstract
Abstract Wet oxidation technology is a kind of advanced oxidation technology, which is suitable for the treatment of high concentration, toxic, harmful and biodegradable organic wastewater. WAO technology has been effectively applied in the following wastewater treatment: cyanide wastewater, sulfur wastewater, paper black liquor, municipal sludge, pesticide wastewater, coal gasification wastewater and activated carbon regeneration. (2) chemical reaction between dissolved oxygen and matrix. The front part of WAO reaction is controlled by oxygen mass transfer and the back part is controlled by reaction kinetics. It is generally believed that the WAO reaction mainly belongs to the free radical reaction, which goes through four stages of induction, proliferation, degradation and termination. The reaction temperature is the main factor affecting the wet oxidation reaction.
