Description

Technical Field

[0001] The utility model relates to the technical field of MABR membranes, and particularly to a connection structure of an aeration type MABR membrane module. Background Technique

[0002] The MABR membrane aeration biofilm reactor, or the EHBR enhanced coupled biofilm reactor, is a new type of water treatment process combining membrane technology and biofilm technology. It utilizes the synergistic effect between the breathable membrane and the attached growth biofilm layer. The breathable membrane is used to transfer oxygen to the biofilm layer attached to the surface of the breathable membrane. At the same time, ammonia and organic matter substrates diffuse from the sewage to the biofilm layer, thereby consuming and degrading water pollutants to meet the water pollution prevention and control standards. In the biofilm of the MABR, EHBR membrane process, oxygen, organic matter, and nutrients in water are mass-transferred in opposite directions. Therefore, the biofilm of MABR is actually a nitrifying biofilm, that is, heterotrophic bacteria and autotrophic bacteria do not conflict, so it is easier to carry out nitrification better on the entire biofilm interface, and denitrification is carried out in the outside mixed liquor to achieve simultaneous nitrification and denitrification, which is completely different from the traditional biofilm process. On the left, the traditional biofilm medium has a biofilm growing on it, and oxygen, organic matter, and nutrients in water enter the biofilm from the outside, thus there is a problem of competition between heterotrophic bacteria and autotrophic bacteria.

[0003] However, it still has some disadvantages. For example, the combined aeration type MABR membrane module usually adopts a complex fixing method, and the MABR membrane cannot be quickly disassembled and replaced individually. It takes a lot of time for disassembly and installation work, and the tightness of the MABR membrane cannot be adjusted, which will reduce the filtration effect. When filtering, the base cannot be fixed in the water, and displacement will occur, resulting in a reduction in filtration efficiency and inconvenience in use.

[0004] To solve the above problems, a connection structure of an aeration type MABR membrane module is proposed in this application. Content of the Utility Model

[0007] Preferably, a MABR membrane is movably connected to the outer surface of the lower end of the fixing strip, and a limiting strip is fixedly connected to the outer surface of the upper end of the MABR membrane.

[0015] Through the adjusting shaft and the fixed disk provided by the present utility model, when the staff installs the fixed base into the pool, rotate the rotating handle to make the adjusting shaft and the fixed disk expand and contract. While expanding and contracting, it is fixed to the wall, and the fixing ring prevents the adjusting shaft from moving.
