Waste water treatment by air oxidation

Wet catalytic oxidation, the standard abbreviation CWO, refers to raising the
temperature of wastewater to 180 ℃ - 325 ℃, using the oxygen in the air to
increase the solubility with the increase of pressure. Under the action of
catalyst, oxygen molecules and organics in wastewater undergo a rapid oxidation
reaction, resulting in ring breaking and chain breaking of organics, which are
collectively referred to as degradation.
The principle of degradation reaction is free radical chain reaction. The
primary products of oxidative degradation are simple organic acids and organic
alcohols below C4. Some of the degradation products will be deeply degraded and
mineralized into carbon dioxide to form the removal of TOC. The degradation
rule is that the higher the reaction temperature is, the greater the proportion
of deep degradation to carbon dioxide is. The catalytic strength can reduce
the energy level of degradation reaction and increase the speed of degradation
reaction. The top of wet catalytic oxidation process is supercritical
oxidation.
