Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment equipment, in particular to an MBR membrane wastewater treatment equipment for food processing. Background Art

[0002] MBR membrane, also known as membrane bioreactor, is a new water treatment technology that combines a membrane separation unit with a biological treatment unit. During use, the membrane component replaces the terminal secondary sedimentation tank of traditional biological treatment technology, maintains a high activated sludge concentration in the bioreactor, and increases the organic load of biological treatment, thereby reducing the footprint of sewage treatment facilities and reducing the amount of residual sludge by maintaining a low sludge load.

[0003] At present, membrane bioreactors can retain microorganisms with a long generation cycle due to their effective interception effect, and can achieve deep purification of sewage. At the same time, nitrifying bacteria can fully reproduce in the system, and their nitrification effect is obvious, which provides the possibility for deep phosphorus and nitrogen removal. Therefore, they are widely used in sewage treatment, water resource reuse and other fields, and the relevant technologies of wastewater treatment equipment formed by MBR membranes are also in a public state. For example, the patent document with application number 202322294377.X discloses "an MBR membrane module for kitchen wastewater treatment, including a main body mechanism, an auxiliary mechanism and a shock-absorbing mechanism, The auxiliary mechanism is located at the outer end of the main mechanism, and the shock-absorbing mechanism is located inside the main mechanism. The main mechanism also includes a cleaning component, a solid particle filter, an MBR diaphragm, a submersible pump, a connecting pipe and a drainage pipe for food wastewater treatment. The solid particle filter is fixedly installed inside the food wastewater treatment tank. After implementation, "the MBR membrane module used for food wastewater treatment, by installing the main mechanism, can enable the motor to drive the rotating rod, the rotating frame and the cleaning brush to rotate on the solid particle filter, so that the solid particle filter will not be blocked, thereby improving the efficiency of food wastewater treatment."

[0004] However, from the actual production perspective, although the simultaneous cleaning of the filtration structure during use can maintain the filtration efficiency to a certain extent, as the use time increases, more and more solid dirt will be cleaned out. If it is not cleaned in time, it will still cause the pretreatment of the MBR membrane unit before operation to be not smooth, affecting the operating efficiency of the overall equipment.

[0032] Working principle:

[0033] Example 1

[0034] Before the MBR membrane processor 3 treats the sewage, the sewage is first pumped into the second treatment box 2 through the first liquid delivery valve pipe 7 by the water pump 5, and then filtered by the inclined filter plate 4 inside the second treatment box 2. The sewage after filtering and pre-treatment will enter the interior of the first treatment box 1 through the connecting pipe and then be treated again by the MBR membrane processor 3;

[0035] After the inclined filter plate 4 has been used for a certain period of time, the valve on the second infusion valve tube 8 can be opened, and then the second infusion valve tube 8 will divert part of the sewage and transport it to the inside of the self-cleaning pipe 6. After multi-point diversion through the self-cleaning pipe 6, it will be flushed along the top surface of the inclined filter plate 4, and then the solid particles filtered out from the surface of the inclined filter plate 4 will be concentrated into the semicircular plate structure of the inclined filter plate 4, thereby maintaining the efficient filtering effect of the inclined filter plate 4.

[0036] Example 2

[0037] Before the MBR membrane processor 3 treats the sewage, the sewage is first pumped into the second treatment box 2 through the first liquid delivery valve pipe 7 by the water pump 5, and then filtered by the inclined filter plate 4 inside the second treatment box 2. The sewage after filtering and pre-treatment will enter the interior of the first treatment box 1 through the connecting pipe, and then be processed again by the MBR membrane processor 3. After the inclined filter plate 4 has been used for a certain period of time, the valve on the second liquid delivery valve pipe 8 can be opened, and then the second liquid delivery valve pipe 8 can be used to divert part of the sewage and transport it to the interior of the self-cleaning pipe 6. After the multi-point diversion of the self-cleaning pipe 6, it is flushed along the top surface of the inclined filter plate 4, and then the solid particles filtered out on the surface of the inclined filter plate 4 are concentrated toward the semicircular plate structure of the inclined filter plate 4, thereby maintaining the efficient filtering effect of the inclined filter plate 4;

[0038] When the entire equipment cannot be paused for cleaning for a long time, the servo motor in the power output component 10 is started, and the power output component 10 drives the screw rod 9, so that the screw rod 9 spirally conveys the solid dirt with a semicircular plate structure, so that it is automatically transported through the extension cylinder 11 and the filter mesh disk 12, thereby completing its own cleaning operation while meeting the operation of the equipment.
