Abstract

According to the wastewater treatment oxidation tank provided by the invention, the type, number and specification of the aeration devices are reasonably set, the flexible hose is used for connecting the air inlet and the aeration devices, and the lifting device is used for enabling the aeration devices to lift up and down in the tank in a reciprocating manner; the technical problems that oxidation air is not uniformly distributed in the oxidation tank, and large bubbles are easily generated and directly float and escape are solved.

Description

Technical field [0001] The invention is the technology field of the refining industry catalyzed cracking flue gas desulfurization device equipment, which involves a wastewater treatment tank. Background technique [0002] With the development of the oil refining industry and the country's emphasis on environmental protection, catalytic cracking flue gas desulfurization devices are used as environmental protection devices, and the importance is becoming more and more prominent. This device is mainly discharged after treatment of the flue gas generated during the catalytic cracking process. At the same time, the wastewater generated during the processing of the flue gas treatment process is required to ensure that the chemical oxygen demand (COD) and other indicators are qualified to achieve realization, and realize it to achieve realization. Discharge. The wastewater treatment mainly relies on oxidation tanks. The use of oxygen to transform Asia sulfate in wastewater into sulfate,...
