Catalytic wet oxidation reaction column and the column processing method and apparatus of high concentration organic waste water using

The present invention relates to a process and apparatus for catalytic wet oxidation treatment reaction column and the column using a high concentration of organic waste water treatment. High concentration of organic wastewater (COD≥5000mg / L) passes through the raw water tank (1), the high-pressure pump (2), filter (3), the high pressure buffer tank (4), heat exchanger (5), by reaction column after the distributor is provided with a high pressure liquid (8) (7) at the bottom, compression and compressor (6) and that the gas distributor (9) in contact with high-pressure air in the reaction column (7), and the reaction sufficiently proceeds to a gas-liquid separation tank (10), the separated gas (11) through the exhaust gas discharge standards absorber treatment, waste water separated aqueous phase through a buffer tank (12) uniform discharge standards. This method and apparatus can efficiently handle a variety of continuous high concentration of refractory organic wastewater, COD removal efficiency greater than 95%, the successful industrialization development CWAO processing technology, has a very important significance for the substantial promotion and application of technology in the field of environmental protection .
