Superhigh-efficiency anammox reactor

Abstract

The invention discloses a superhigh-efficiency anammox reactor, which is provided with a sediment zone, a reaction zone and a bracket. The sediment zone is sequentially provided with a first outer cylinder, an overflow weir, a water outlet, a backflow port, an annular wire netting and a two-stage three-phase separator from top to bottom. The two-stage three-phase separator comprises a first gas collecting tube, a first reducing pipe, a second gas collecting tube and a second reducing pipe. The overflow weir is communicated with the water outlet, the backflow port is positioned between the overflow weir and the annular wire netting, the inner ring of the annular wire netting is connected with the outer wall of the first gas collecting tube, and the outer ring of the annular wire netting is connected with the inner wall of the first cylinder. The reaction zone comprises a second outer cylinder, an iron powder carrier, a water inlet tube and a hemispheroid. The reaction zone is connected with the sediment zone through an outer cylinder increasing coupling and is directly connected with the bracket, and both the reaction zone and the sediment zone are provided with dredge pipes. The invention effectively prevents sludge loss, reduces gas disturbance, promotes the natural sedimentation of granules, reduces the toxicity of the base material and ensures the operating performance of the reactor to be efficient and stable.

Description

technical field [0001] The invention relates to a reactor, in particular to an ultra-efficient anaerobic ammonium oxidation reactor. Background technique [0002] With the acceleration of industrialization, the discharge of nitrogen-containing wastewater has increased sharply, which has caused severe eutrophication of surface water bodies and seriously threatened the health and survival of humans and organisms. At present, nitrogen treatment mainly relies on biological treatment technology represented by traditional nitrification-denitrification process. However, the process load is low, the sludge output is large, and the treatment cost is high. [0003] In recent years, a number of new processes represented by anaerobic ammonium oxidation have emerged in biological nitrogen removal. Their main features are high load and low operating cost, so they have become the most valuable wastewater denitrification technology. At present, the anaerobic ammonium oxidation process ha...
