Problems solved by technology

[0004] However, there are still obvious defects in its use: 1. The above-mentioned device is provided with a microporous aeration device, but after long-term use, the aeration holes are easily blocked by impurities in the waste water, resulting in aeration The device fails; 2. The above-mentioned device is equipped with a hollow fiber membrane module. Similarly, after being used for a long time, the hollow fiber membrane module will also reduce the effect of sewage treatment due to the attachment of impurities. At this time, it needs to be cleaned manually , very tedious and inefficient

Embodiment 1

[0030] A membrane bioreactor wastewater treatment equipment includes a treatment box 1, and a water inlet pipe 2 is communicated with the lower end side wall of the treatment box 1. Waste water is introduced in different directions, and the inner cavity of the treatment box 1 is sequentially fixed with a coarse grid 6, a fine grid 7 and a partition 8 from bottom to top. There are fine through holes 701, and the diameter of the thick through holes 601 is larger than that of the fine through holes 701. Therefore, when the waste water passes through the coarse grid 6 and the fine grid 7 in turn, preliminary filtration can be achieved, and then large impurities are intercepted. 8 is a fully enclosed type, so that the inner cavity of the treatment box 1 can be divided into two parts, an aeration pipe 9 is arranged above the partition plate 8, and a plurality of aeration holes 901 are opened on the aeration pipe 9, and the aeration holes 901 is provided with an anti-blocking net, th...

Embodiment 2

[0034] A membrane bioreactor wastewater treatment equipment includes a treatment box 1, a water inlet pipe 2 is communicated with the lower end side wall of the treatment box 1, a sewage discharge funnel 3 is communicated with the bottom of the treatment box 1, and a sewage discharge funnel 3 is fixedly arranged below. The sewage pipe 4, the sewage pipe 4 is provided with a sewage valve 5, and the opening and closing of the sewage valve 5 can be used to control whether the sewage pipe 4 is opened or not. After a period of use, the large dirt in the wastewater will be intercepted and precipitated. In the sewage funnel 3, the sewage valve 5 can be opened regularly, and the sewage can be discharged through the sewage pipe 4. The inner cavity of the treatment box 1 is fixedly arranged with a coarse grid 6, a fine grid 7 and a The partition plate 8, the coarse grid 6 is provided with a coarse through hole 601, and the fine grid 7 is provided with a fine through hole 701. The diamete...

Embodiment 3

[0038] On the basis of the above-mentioned first and second embodiments, this embodiment further discloses and defines the specific structure of the power device. Specifically, the power device includes a rotating electrical machine 10 , and the rotating electrical machine 10 is fixedly arranged on the support plate 11 . , the support plate 11 is fixedly arranged on the outer wall of the processing box 1. In this embodiment, the support plate 11 is L-shaped, which is convenient for placing the rotary motor 10. The output shaft of the rotary motor 10 is fixedly provided with a rotary shaft 12, and the rotary shaft 12 is far away from the rotation. One end of the motor 10 is fixed on the air pump 13, so the rotating motor 10 in the starting state can drive the air pump 13 to rotate through the rotating shaft 12, and the air pump 13 is communicated with the aeration pipe 9 through the conveying air rod 14. Therefore, the air pump 13 can pass through the conveying air rod. 14 drive...

Abstract

The invention provides membrane bioreactor wastewater treatment equipment which comprises a treatment box, and an aeration pipe can be driven by a power device to rotate; a membrane assembly is arranged above the aeration pipe in a non-contact mode, MBR membranes are fixedly arranged on the two sides of the supporting rod, and a lifting pipe is arranged on the side wall of the treatment box in a communicating mode. The bottom of the connector pipe is communicated with a first flushing cover, the first flushing cover is used for flushing the MBR membrane, the flushing pipe is communicated with a second flushing cover, the second flushing cover is used for flushing the aeration holes and the anti-blocking net in the aeration holes, an opening of the flushing pipe is provided with an elastic sealing section, and the opening of the flushing pipe is communicated with the first flushing cover. A power pump switch is arranged in the elastic sealing section in a wrapped mode and is in signal connection with the power pump. The membrane bioreactor wastewater treatment equipment provided by the invention is internally provided with the backflow flushing device, so that the aeration holes of the aeration pipe and the MBR membrane of the membrane assembly can be respectively flushed, and the use effect is better.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to membrane biological reactor wastewater treatment equipment. Background technique [0002] Membrane bioreactor (MBR) process is a new wastewater treatment technology that organically combines membrane separation technology and biotechnology. It uses membrane separation equipment to retain the activated sludge and macromolecular organic substances in the biochemical reaction tank, saving the secondary sedimentation tank. Therefore, the concentration of activated sludge is greatly improved, and the hydraulic retention time (HRT) and sludge retention time (SRT) can be controlled separately, while the refractory substances are continuously reacted and degraded in the reactor. Therefore, the membrane bioreactor (MBR) process greatly enhances the function of the bioreactor through membrane separation technology. Compared with traditional biological treatment methods, it i...
