Description

Technical Field

[0001] The utility model relates to the technical field of MBR membrane modules, in particular to a module-assembled MBR membrane module. Background Art

[0002] MBR is a new water treatment technology that combines a membrane separation unit with a biological treatment unit. It uses membrane components to replace the secondary sedimentation area in the bioreactor to maintain a high activated sludge concentration, reduce the footprint of sewage treatment facilities, and reduce the amount of sludge by maintaining a low sludge load. Compared with traditional biochemical water treatment technology, MBR has the following main features: high treatment efficiency, good effluent quality, compact equipment, small footprint, easy automatic control, and simple operation and management.

[0003] The main equipment of MBR is the membrane module, on which a large number of hollow fiber ultrafiltration membranes or flat membranes are installed. The outer diameter of the ultrafiltration membrane is generally about 2mm, the inner diameter is about 1mm, and the ultrafiltration surface is covered with small holes of 0.04-0.1 microns. From the outside, the hollow fiber membrane filaments look like thin plastic filaments. The hollow fiber membranes are arranged vertically and parallelly on the membrane module. When the membrane filaments are actually used in sewage treatment, the two end outlets of several membrane filaments need to be cast into two rectangular plastic membrane shells with epoxy resin to form a sealing structure, that is, the middle part is the membrane filament, the two ends are the plastic membrane shells, and there are clean water outlets on the edge of the membrane shell, so as to form a membrane module. Installing several membrane modules on a bracket constitutes a membrane module. The existing membrane shell assembly is generally connected to the bracket by a thread. Although it can be disassembled, the disassembly process is relatively troublesome, which brings inconvenience to the cleaning or replacement of the hollow fiber membrane, and it is not convenient to adjust the distance between the membrane modules, so that the distance between two adjacent membrane modules cannot be adjusted according to the different filtered materials. In view of this, we propose a modular assembled MBR membrane unit. Utility Model Content
