An anaerobic ammonia oxidation reactor

Abstract

The invention discloses an anaerobic ammonium oxidation reactor, which relates to the technical field of sewage treatment, and comprises a tank body and a degassing cover. A nitrosation reaction device is arranged under the degassing hood. The anammox reaction device has the same structure as the nitrosation reaction device. It includes a fixed frame, a movable frame, and a limit groove. The fixed frame and the limit groove are both connected to the inner wall of the tank. Fixed connection, the movable frame can slide up and down in the limit groove, a filler is arranged between the fixed frame and the movable frame, and a circulation device is also included. The circulation device is used to pump the sewage treated by the anammox reaction device back to the anaerobic ammonia Below the oxidation reaction unit and below the nitrosation reaction unit, and control the circulating flow of the two lines respectively. The reactor integrates nitrosation reaction and anaerobic ammonia oxidation reaction, and has good sewage denitrification treatment effect and high efficiency.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an anaerobic ammonia oxidation reactor. Background technique [0002] The anaerobic ammonium oxidation reactor in the prior art can only realize the anaerobic ammonium oxidation reaction process, its ability to treat ammonia nitrogen in sewage is relatively limited, and it is difficult to independently achieve high-efficiency and high-speed sewage denitrification treatment. Other sewage treatment equipment is used to build a huge sewage treatment system. In most cases, it needs to be fabricated and installed on the construction site, and the area is large, the equipment and construction costs are high, and the operation and maintenance are difficult. In the usual anammox reaction device, anammox bacteria or free growth, or the packing is fixed installation, and the sewage cannot be fully circulated, the bacteria cannot fully transfer and react with the pollutants in the ...

AI Technical Summary

Problems solved by technology

[0002] The anaerobic ammonium oxidation reactor in the prior art can only realize the anammox reaction process, and its ability to treat ammonia nitrogen in sewage is relatively limited, and it is difficult to independently achieve efficient and high-speed sewage denitrification treatment. Building a huge sewage treatment system together with other sewage treatment equipment, in most cases, it needs to be manufactured and installed on the construction site, and it occupies a large area, the cost of equipment and construction is high, and operation and maintenance are difficult

In the usual anammox reaction device, the anammox bacteria grow freely, or the filler is fixedly installed, and the sewage cannot be fully circulated, the bacteria cannot fully transfer and react with the pollutants in the sewage, and the sewage degasses. Nitrogen treatment efficiency is low

In addition, the anammox bacteria dissociate in the reacted sewage during the reaction, and the growth rate of the colony is slow. The anaerobic ammonium oxidation device in the prior art generally has the problem of bacterial flora loss after a period of reaction, which affects the denitrification of sewage.
