technical field

The present application relates to the technical field of sewage treatment, more specifically, to a circulation treatment aeration oxidation tank and its method.

Background technique

Aeration refers to the process of forcibly transferring the oxygen in the air to the liquid. Its purpose is to obtain enough dissolved oxygen and strengthen the contact between the organic matter in the pool and the microorganisms and dissolved oxygen, so as to ensure that the microorganisms in the pool have sufficient dissolved oxygen. , to oxidize and decompose organic matter in sewage.

The prior art publication number is CN213171802U, which provides a circulation treatment aeration oxidation tank for sewage treatment, which performs secondary treatment on the treated sewage through the filter tank, which improves the treatment quality, and the sewage that does not meet the standard passes through the circulation treatment pipe. It flows into the sewage treatment tank and is treated again to achieve the effect of circular treatment, so as to enhance the sewage treatment effect; the sludge plate is washed by pumping the treated clean water, and then pumped out of the sewage treatment tank by the sewage suction pump for treatment, thereby Increase the efficiency of sewage cleaning, and also reduce the cost and waste of resources caused by multiple sewage cleaning. Although the above-mentioned device can clean the bottom sludge in the tank through the sludge plate and the sewage suction pump, it is relatively slow to use the cleaning nozzle to flush the sludge on the dredging plate, which affects the working efficiency of the sewage aeration oxidation tank; moreover, the sewage treatment tank and filtration The volume of the pool is different.
