Embodiment 1

[0060] A membrane bioreactor, comprising a membrane bioreactor body, and several shuttlecock bodies 3 installed on the membrane bioreactor body, said shuttlecock body 3 comprising: a fixed shaft 31, a bristle body 32 and a rotating member 33, Such as Figure 1-Figure 3 shown. Wherein, the bristle body 32 is connected to the fixed shaft 31; the rotating member 33 is arranged on the fixed shaft 31 for making the bristle body 32 swing and rotate freely.

[0061]In the present invention, a shuttlecock body is added on the membrane bioreactor body, and the specific structure of the shuttlecock body is optimized. The shuttlecock body includes a fixed shaft, a bristle body and a rotating part; the rotating part is used to make the bristle body free Swing and rotation, that is, under the action of hydraulic impact or electric current, the bristle body realizes the functions of 360° rotation, stretching and shaking around the central axis. The size of the flying shuttlecock in the pr...

Abstract

The invention discloses a membrane bioreactor. The membrane bioreactor comprises a plurality of flying shuttlecock bodies mounted on a membrane bioreactor body, wherein each flying shuttlecock body comprises a fixed shaft, a bristle body and a rotating piece; the bristle body is connected to the fixed shaft; and the rotating piece is arranged on the fixed shaft and is used for enabling the bristlebody to freely swing and rotate. The membrane bioreactor further comprises a suspension body and a plurality of filaments for providing buoyancy and motion support for the suspension body. The membrane bioreactor disclosed by the invention has the advantages of long operation period, light membrane pollution and good nitrogen and phosphorus removal effect. When the aeration rate is reduced, a good turbulence state is still kept in the membrane bioreactor, so that the oxygen mass transfer and energy transfer processes are further enhanced, and the problem of membrane pollution caused by excessive concentration of pollutant distribution is relieved; meanwhile, the problem that sludge flocs are damaged due to high aeration intensity can be relieved, and the membrane pollution or the membranereplacement cost after membrane damage is greatly reduced.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a membrane bioreactor used in water treatment. Background technique [0002] Membrane bioreactor (MBR), as a new sewage treatment method, organically combines membrane separation and biological treatment technology to replace the secondary sedimentation tank in the traditional activated sludge process (CAS) to improve the separation efficiency of sludge and water. Compared with CAS, MBR has the advantages of good effluent quality, small footprint, and less sludge production. The MBR in the prior art is divided into three types: split type, integrated type and composite type. Among them, the composite type MBR is based on the integrated structure in which fillers are added in the membrane bioreactor, and the membrane bioreactor has membrane modules, guide rails The plate is mounted on the membrane module. In this composite MBR, on the one hand, the filler provides a carrier for mi...
