Anaerobic ammonia oxidation reactor

Abstract

The invention discloses an anaerobic ammonoxidation reactor, comprising the reactor body, inlet pipe installed in the lower of the reactor, sealed cover, sludge settling area and overflow dam equipped in the upper of the reactor, air outlet equipped on the sealed cover, sludge reflux seam in the settling area equipped in the lower part of the sludge settling area, and stirring in the reactor. The characteristics of the invention comprises:1) the microorganism for anaerobic ammonoxidation exists in granule sludge form, the potential of the anaerobic ammonoxidation is great and the sludge and water separation effect is sound; 2) the settling room is equipped in the outer race of the reactor upper part, which makes the structure be compact; 3) the stirrer runs at a certain speed which makes the wastewater in the reactor contacts with the granule sludge completely to intensify the mass transfer process; 4) the fluidization property of the sludge is good and the running property is stable; 5) the anaerobic ammonoxidation property of the reactor is good, the reactor can bear high concentration of ammonia and nitrite and possesses high volumetric conversion rate.

Description

technical field [0001] The invention relates to an anaerobic ammonia oxidation reactor. Background technique [0002] With the development of industrial and agricultural production and the improvement of people's living standards, the discharge of nitrogenous organic matter has increased dramatically. Secondary biological treatment has been launched one after another. Although it has played a good role in curbing organic pollution, the high nitrogen content in the effluent is still a serious source of environmental pollution. Nitrogen pollution is extremely harmful. Ammonia entering the water body can not only induce "eutrophication" and cause the disorder of the aquatic ecosystem, but also consume dissolved oxygen, resulting in hypoxia in the water body, affecting the oxygen transfer of strontium in fish, making fish Lethal; react with chlorine gas to form chloramine, which affects chlorination disinfection treatment. Therefore, it is imperative to control nitrogen pollut...

Problems solved by technology

Secondary biological treatment has been launched one after another. Although it has played a good role in curbing organic pollution, the high nitrogen content in the effluent is still a serious source of environmental pollution.

Separating the activated sludge with the secondary settling tank and sending it back to the anaerobic tank through the reflux pump not only increases the equipment and consumes power, but also destroys the structure of the activated sludge, which is not conducive to the formation of granular sludge with excellent sedimentation performance and the separation of mud and water
