Integrated apparatus for processing a high concentration of chemical flooding oil field waste water a strongly oxidizing gas in contact with a wet method

A strongly oxidizing gas contacts a wet method processing apparatus of high concentration chemical flooding integrated oilfield wastewater. The apparatus comprises a coarse air filter, coarse filter air through line sequentially connecting the muffler, an air compressor, cold and dry air, a fine filter air, oxygen, inert gas generator, contact oxidation tank, exhaust collector, wherein: the inert gas is mounted on the exhaust gas recycling line detector device, connected with a circulating water cooling system, the contact is mounted on the tank line monitoring COD oxide, COD online monitor and an inert gas generator PLC control respectively of the gas generating activity signal line. This device is mounted COD online monitor reactive gas can be effectively utilized, to avoid waste, exhaust gas recycling to achieve the purpose of environmental protection.
