MBR reactor

Abstract

The invention discloses an MBR reactor. A through groove is formed in the upper surface of a tank body, a bearing is fixedly connected to the inner side wall of the through groove, a motor is in threaded connection with the upper surface of the tank body, an output shaft of the motor is fixedly connected to an inner ring of the bearing, and one end of the output shaft of the motor is inserted intothe tank body and fixedly connected with a rotating shaft; two stirring rods are symmetrically welded on the outer side wall of the rotating shaft; a motor drives a stirring rod to rotate, so that sewage in a tank body is stirred, sludge in the sewage is separated from water through cooperation of an aerator, the water is discharged from the interior of the tank through a water discharging pipe,and the sludge is intercepted by a filtering net, so that the sludge is prevented from being discharged from the interior of the tank body; when the rotating shaft rotates, the sleeve is driven to rotate, so that the inner wall of the tank body is cleaned through the brush, sludge accumulation on the inner wall of the tank body is prevented, and subsequent sewage treatment is not influenced.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an MBR reactor. Background technique [0002] In the field of sewage treatment and water resource reuse, MBR, also known as Membrane Bio-Reactor (Membrane Bio-Reactor), is a new water treatment technology that combines a membrane separation unit with a biological treatment unit. According to the structure of the membrane, it can be divided into flat membrane, tubular membrane and hollow fiber membrane, etc., and can be divided into microfiltration membrane, ultrafiltration membrane, nanofiltration membrane, reverse osmosis membrane and so on according to the membrane pore size. [0003] During the sewage treatment process of the existing MBR reactor, the sludge in the sewage will adhere to the inner wall of the tank, thereby affecting the subsequent sewage treatment. The sludge accumulates on the inner bottom wall of the tank, which is easy to cause The blockage of the s...

Problems solved by technology

[0003] During the sewage treatment process of the existing MBR reactor, the sludge in the sewage will adhere to the inner wall of the tank, thereby affecting the subsequent sewage treatment. The sludge accumulates on the inner bottom wall of the tank, which is easy to cause The blockage of the sewage pipe makes the stains in the tank unable to be discharged smoothly. Therefore, an MBR reactor is proposed
