Stirring device used for circulating membrane contact bioreactor for river water

Abstract

The invention discloses a stirring device used for a circulating membrane contact bioreactor for river water, and relates to the technical field of MBR membrane bioreactor wastewater treatment devices. The stirring device comprises a box, a stirring barrel is arranged in the box, the upper surface of the stirring barrel is fixedly connected with a seal piece, and the upper surface of the seal piece is in overlapping connection with the upper surface of the inner wall of the box. The lower surface of the stirring barrel is fixedly connected with a plurality of sliders, and the sliders are slidably connected to first sliding grooves in the lower surface of the inner wall of the box. According to the stirring device used for the circulating membrane contact bioreactor for the river water, thestirring barrel can move relative to a stirring rod and a stirring device body, and accordingly, raw materials at the corners in the stirring barrel can be sufficiently stirred and mixed; because theinner wall of the stirring barrel can make contact with a scraper blade in the reciprocating process of the stirring barrel, under the action of the scraper blade, sticky materials adhering to the inner wall of the stirring barrel can be effectively removed, and the work efficiency of workers is improved.

Description

technical field [0001] The invention relates to the technical field of MBR membrane bioreactor sewage treatment equipment, in particular to a stirring device for a river water circulation membrane contact bioreactor. Background technique [0002] In the field of sewage treatment and water resource reuse, MBR, also known as membrane bioreactor, is a new type of water treatment technology that combines membrane separation unit and biological treatment unit. Membrane-bioreactor is membrane separation technology and biological treatment technology. A new type of wastewater treatment system that combines organically, replaces the terminal secondary sedimentation tank of traditional biological treatment technology with membrane modules, maintains a high concentration of active sludge in the bioreactor, increases the organic load of biological treatment, thereby reducing the footprint of sewage treatment facilities, and through To maintain low sludge load and reduce the amount of e...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a stirring device for a river water circulation membrane contact bioreactor, which solves the problem that when the existing stirring device stirs and mixes the river water and other materials, since the stirring structure is usually fixed, As a result, the materials at the inner corners of the mixing tank cannot be fully stirred and mixed, and the river water also contains a large amount of viscous substances, which are easy to adhere to the inner surface of the mixing tank, which is not only inconvenient to clean, but also causes the mixing tank to be polluted, which is easy to cause The phenomenon of uneven stirring reduces the work efficiency of the user, and also reduces the practicality of the stirring device for the production of insoluble phosphate
