Description

Technical Field

[0001] The present application relates to the field of MBR systems, and in particular to an MBR system suitable for underground sewage treatment plants. Background Art

[0002] The MBR system is a sewage treatment technology that combines biological treatment technology and membrane separation technology to achieve efficient and stable sewage treatment through the use of membrane bioreactors. MBR technology uses microporous membrane filtration to intercept suspended matter and microorganisms in sewage inside the reactor, thereby improving water quality. This technology can effectively remove suspended matter, turbidity, and ammonia nitrogen in sewage, and significantly reduce the number of bacteria and viruses, while reducing energy consumption and floor space. The MBR system can select appropriate membrane materials according to specific needs, such as ultrafiltration membrane, microfiltration membrane or nanofiltration membrane, to meet different water quality and treatment requirements. When using conventional MBR integrated equipment, the purification box is installed in the reserved installation slot. Several connecting pipes and equipment inlets are installed on the top of the purification box. The connecting pipes and equipment inlets make it convenient for staff to enter the purification box. After one end of the purification box is connected to the water source, the water enters the purification box for treatment and is discharged from the water outlet of the purification box.

[0003] Regarding the above-mentioned related technologies, the inventors believe that conventional MBR equipment is often installed underground. After being enclosed by a civil pool or retaining wall, the periphery of the MBR equipment is closed, making it difficult for staff to check the condition of the MBR equipment in time. As a result, the MBR equipment is easily tilted or even collapsed after being subjected to external pressure and material corrosion for a long time.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0006] The MBR system provided in this application is applicable to underground sewage treatment plants and adopts the following technical solutions:

[0007] An MBR system suitable for an underground sewage treatment plant comprises a purification box and a base frame, wherein the top of the purification box is connected to a plurality of connecting pipes, and the plurality of connecting pipes are evenly distributed on the top of the purification box, the top of the purification box is fixedly installed with an equipment room entrance, the top of the base frame is welded with a plurality of shielding frames, the inner wall of the shielding frame is slidably connected to a sliding frame, one end of the sliding frame is fixedly installed with a pressure plate, the inner wall of the shielding frame is fixedly connected to a laser rangefinder, the top of the base frame is fixedly installed with the bottom end of the purification box, the plurality of shielding frames are divided into two groups, and the two groups of shielding frames are symmetrically distributed with the base frame as the axis, one end of the laser rangefinder is electrically connected to a control box by means of a wire, and one end of the control box is fixedly installed with the surface of the equipment room entrance.

[0008] Preferably, a spring is fixedly mounted on one end of the pressure plate, an end of the spring away from the connection between the spring and the pressure plate is fixedly connected to one end of the shielding frame, and the center of the spring and the center of the sliding frame are on the same straight line.

[0009] Preferably, an auxiliary plate is fixedly mounted on one end of the pressing plate away from the connection between the pressing plate and the sliding frame, the size of the auxiliary plate surface is adapted to the size of the pressing plate surface, and the auxiliary plate is a rubber plate.

[0010] Preferably, a connecting hole is opened on the inner wall of the sliding frame, the inner wall of the connecting hole is clamped with a limiting frame, the surface of the limiting frame is slidably connected to the top of the shielding frame, and the size of the bottom end of the limiting frame is adapted to the size of the inner wall of the connecting hole.

[0011] Preferably, a plurality of insertion rods are slidably mounted on the inner wall of the base frame, and the plurality of insertion rods are divided into two groups, and the two groups of insertion rods are symmetrically distributed with the base frame as the axis.

[0012] In summary, this application has the following beneficial technical effects:

One end of the laser rangefinder is electrically connected to the control box on the surface of the equipment entrance, so that the pressure plate is pushed when the purification box is offset. The distance of the pressure plate is detected by the laser rangefinder and displayed through the control box, which is convenient for the staff to check the status of the purification box. One end of the pressure plate is fixedly connected to a spring, and one end of the spring is installed on the surface of the shielding frame so that the pressure plate is pushed by the spring to keep it in contact with the surface of the purification box, thereby avoiding the problem that the pressure plate and the surface of the purification box are separated and the data detected by the laser rangefinder are affected. An auxiliary plate of rubber material is installed on one end of the pressure plate, and one end of the auxiliary plate is in contact with the surface of the purification box, so that the pressure plate can avoid scratching the surface of the purification box by the relatively soft rubber material of the auxiliary plate.

[0014] 2. A connecting hole can also be opened on the inner wall of the sliding frame, and a limiting frame can be opened on the inner wall of the connecting hole.
