Embodiment

[0037] Example: a structure such as figure 1 As shown, a modular omni-directional aeration membrane assembly includes a suction head 1, an aeration pipeline 2, a membrane tow 3 and an aeration head 4.

[0038] The suction head 1 and the aeration head 4 are respectively placed at the two ends of the membrane tow 3 and fixed together with the two ends of the membrane tow 3 respectively. The membrane filament bundle 3 is composed of multiple hollow fiber membrane filaments arranged in parallel. The membrane filaments are hollow and there are many micron-sized pores on the membrane filament wall. Through the pumping action of the water pump, clean water penetrates into the membrane filaments from the tiny pores, and Contaminants are trapped on the outside.

[0039] The hollow fiber membrane is made of polyethylene (PE), vinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE) and other materials. The length is 500-5000mm, preferably the membrane filament bundle contains 400-10...

Abstract

The invention relates to a modular all-direction aeration membrane assembly, which mainly comprises a suction sealing head, an aeration pipeline, a membrane tow and an aeration sealing head. Accordingto the present invention, the aeration pipeline supports the suction sealing head and the aeration sealing head, and directly performs all-direction aeration flushing on the membrane tow, such that the aeration flushing effect on the membrane tow is substantially improved, and the problem that the aeration flushing effect of the existing membrane assembly is insufficient can be effectively solved; with the horizontally oriented aeration hole, the problem that the aeration hole is easy to clog is avoided; by using the consistent and easy-to-expand interface, the quick connection and the optional expansion can be achieved; and the modular all-direction aeration membrane assembly with advantages of good aeration flushing effect, less clogging and strong expandability is provided.

Description

technical field [0001] The invention relates to a membrane aeration device for sewage treatment, and more specifically, to a modular omnidirectional aeration membrane assembly. Background technique [0002] In the field of sewage treatment and water resource reuse, MBR, also known as Membrane Bio-Reactor (Membrane Bio-Reactor), is a new water treatment technology that combines a membrane separation unit with a biological treatment unit. In MBR technology, hollow fiber membranes with micron-sized pores are mostly used as filter elements, and the separation of clean water from pollutants is achieved through the suction or extrusion of water pumps. In the process of separation, it is very important to aerate the membrane filaments to ensure the washing of the membrane filaments and reduce the pollution of the membrane filaments. If there is no aeration to wash the membrane filaments during the suction process, the transmembrane pressure difference rises very rapidly. [0003]...
