Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and specifically relates to a denitrification treatment device. Background Art

[0002] Wastewater treatment: the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse, while wastewater denitrification is the process of removing nitrogen from wastewater to prevent eutrophication of water bodies. It is generally divided into two types: physical and chemical methods and biological denitrification methods.

[0003] After searching, the publication number: CN215924439U discloses a sewage treatment denitrification pool. In the utility model, the gravitational potential energy of the sewage can drive the rotation of the driving impeller when it flows in the inner cavity of the guide shell, and the rotation of the driving impeller drives the rotation of the supporting shaft rod. Through the transmission action of the synchronous component between the supporting shaft rod and the connecting shaft rod, the rotation of the dosing shaft rod drives the rotation of the dosing roller. Through the rotation of the dosing roller, the dosing slot can put the powder in the inner cavity of the dosing bucket into the sewage, realizing automatic dosing. With the use of a vibration motor, the denitrification reaction is more complete. However, this device does not have fine filtration before the denitrification reaction, resulting in the microorganisms in the denitrifier combining with a small amount of impurities and sludge in the reclaimed water, causing loss of the denitrifier, thereby increasing the cost of denitrification.

[0004] Therefore, a denitrification treatment device is designed to solve the above problems. Utility Model Content

[0006] The metering pump can introduce the purified sewage from the discharge pipe into the interior of the vacuum anaerobic tank. Under anaerobic conditions, microorganisms directly act as electron donors, using nitrite and nitrate as electron acceptors to convert nitrogen compounds into N2 or use nitrate electron acceptors to oxidize ammonia. This makes the device do not need an external organic carbon source as an electron donor, effectively saving the cost of wastewater treatment.
