Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, specifically to an MBR membrane bioreactor that is easy to disassemble. Background Technology

[0002] Membrane bioreactor (MBR) is a novel water treatment technology that combines membrane separation units with biological treatment units. It replaces secondary sedimentation tanks with membrane modules, maintains a high concentration of active sludge in the bioreactor, reduces the footprint of wastewater treatment facilities, and reduces sludge volume by maintaining a low sludge load.

[0003] Existing MBR (Membrane Bioreactor) piping connections typically use flanges, welding, adhesive bonding, or unions. These connection methods often have strict requirements on pipe dimensions and are not easily disassembled after on-site installation. If maintenance, replacement, or the addition of new membrane modules is needed, the existing piping system must be damaged and reinstalled. This increases installation costs, extends the construction period, and also affects the operation of the MBR.

[0004] Therefore, we propose to design an MBR membrane bioreactor that is easy to disassemble. Utility Model Content

The multiple MBR membrane modules are stacked to form a complete MBR module. Each MBR membrane module can be disassembled and assembled individually, or the entire MBR module can be disassembled and assembled in a unified manner.

[0010] As a preferred embodiment of the easily disassembled MBR membrane bioreactor described in this utility model, the connecting pipe includes two clamps, which are fixed together by bolts. The detachable connecting pipe design facilitates flexible fixing and disassembly of the transfer pipe.

[0011] As a preferred embodiment of the easily disassembled MBR membrane bioreactor described in this utility model, a connecting pipe is fixedly connected to the top of the effluent main pipe. The connecting pipe corresponds to the position of the transfer pipe at its top. The connecting pipe is also fixedly connected to the transfer pipe through a connecting pipe, which facilitates the connection of each effluent branch pipe to the effluent main pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model allows for standardized production through mutual cooperation, facilitating on-site installation and disassembly. In actual use, if maintenance, repair, or replacement of MBR membrane modules is required, a single or a single MBR module can be removed by disassembling the detachable adapter pipe without affecting the use of other MBR modules.
