Moving bed biofilm reactor deposition integrated denitrification reaction tower

Abstract

The invention relates to a moving bed biofilm reactor deposition integrated denitrification reaction tower. The moving bed biofilm reactor deposition integrated denitrification reaction tower comprises a moving bed biofilm reactor and a deposition pool arranged at the periphery of the side wall of the moving bed biofilm reactor, the moving bed biofilm reactor is loaded with suspended filler, an aeration device is arranged at the edge of the bottom, a jet flow water distributor is further arranged in the center of the bottom, a water inlet is formed, a deposition pool inlet is further formed inthe side wall, a sludge reflowing opening is formed below the deposition pool, sludge flowing out of the sludge reflowing opening is mixed with inlet water, is afterwards jetted out of the edge of the bottom of the moving bed biofilm reactor through the jet flow water distributor and is then in contact with the suspended filler to form mixed liquid, and then through upward lifting of the aerationdevice, a hydraulic circulation denitrification environment of aerobic and anoxic alternating is formed. The deposition function is integrated while efficient denitrification is achieved, the technical problems that the suspended filler in the tower-type denitrification reactor is easily lost and running and flowing are not uniform are solved, the structure is compact, the occupied area is small,running is simple, timely power-free sludge reflowing is achieved, and energy is obviously saved.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, and relates to a biological denitrification device for organic wastewater, in particular to a biological moving bed sedimentation integrated denitrification reaction tower. Background technique [0002] The fluidized bed biofilm reactor is a new type of biofilm reactor in the recent denitrification reaction process. It is generally connected in sequence with anaerobic tank, anoxic tank, fluidized bed reactor and sedimentation tank. During the operation of the whole process, the equipment is scattered, the control is difficult, and the filler loss is serious; as the main equipment, the fluidized bed biofilm reactor increases with the operation time, and the filler biofilm thickens, and the traditional microporous aeration and Unreasonable arrangement will cause the filler to gradually move unevenly and stratify, so that the equipment usually has a large dead angle, which seriously...
