指采用过氧化氢、臭氧或催化剂进行深度氧化。

"Advanced chemical oxidation processes make use of (chemical) oxidants to reduce COD/BOD levels, and to remove both organic and oxidisable inorganic components. The processes can completely oxidise organic materials to carbon dioxide and water, although it is often not necessary to operate the processes to this level of treatment

A wide variety of advanced oxidation processes are available:

chemical oxidation processes using hydrogen peroxide, ozone, combined ozone & peroxide, hypochlorite, Fenton's reagent etc.
ultra-violet enhanced oxidation such as UV/ozone, UV/hydrogen peroxide, UV/air
wet air oxidation and catalytic wet air oxidation (where air is used as the oxidant)"
