Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to an MBR pool with a backwashing function. Background Art

[0002] In hospitals or disease control centers, residual liquid medicines often appear, generating a large amount of sewage, especially medical wastewater containing pathogens and drug components. Sewage treatment is required to ensure that the effluent water quality meets national standards. Therefore, the MBR pool is needed.

[0003] For example, the MBR membrane sewage treatment device with automatic backwashing function, which is disclosed in patent publication number CN212024893U, includes an MBR membrane box, a water collection well and a high-level water tank. The horizontal height of the high-level water tank is higher than that of the water collection well. The horizontal height of the top of the inner cavity of the water collection well is higher than that of the MBR membrane box. An MBR membrane assembly is arranged in the MBR membrane box. The MBR membrane box is connected to the water collection well through an outlet pipe. An outlet valve is arranged on the outlet pipe. The lower part of the water collection well is connected to the input end of the pump through a connecting pipe. The output end of the pump is connected to the high-level water tank through an inlet pipe. An inlet valve is arranged on the inlet pipe. A drain pipe is arranged on the high-level water tank. The gravity of the water in the high-level water tank is used to transport the water to the water collection well through its own weight, and then the water enters the MBR membrane box to backwash the MBR membrane assembly, thereby avoiding the use of a backwash pump, saving costs, and reducing the occupied area.

[0004] However, during the use of the above equipment, due to the setting of its internal high-level water tank, the height to the MBR membrane box is different, which makes it inconvenient to adjust the flushing angle, resulting in flushing dead angles and reduced work efficiency. Therefore, in response to this situation, we propose a more convenient and practical MBR pool that meets the usage needs. Utility Model Content
