Waste Water Treatment Technology for COD of High Concentration

Catalytic Wet Oxidation has an outstanding treatment effect for many pollutants of high concentrations and bio-degradation resistance. Compared with traditional oxidation treatment technology, CWO possesses prominent advantages of high efficiency and no secondary pollution, and more. Temperature requirement for reaction is about 100-350 °C, pressure requirement 2-25 MPa, and method requirement a high pressure reactor, or either mechanical or magnetic agitations to mix the air with the liquid, or a fixed bed reactor for gas-solid-liquid three-phase catalytic reaction. With its high efficiency, low energy consumption and less cost, CWO has gained popularity in industrial application.
