China is a country with serious water shortage, and the per-capita water resource amount is only 1/4 of the per-capita water resource amount in the world. At present, the recycling rate of industrial sewage in China is only 6%, and the recycling rate of municipal sewage is lower and far lower than the level of developed countries. The membrane technology is a new interdisciplinary technology developed in the sixties of the last century, and has the excellent characteristics of high efficiency, energy conservation, environmental protection, no pollution, direct recycling of filtered substances and the like, so that the membrane technology is widely popularized and applied in various fields at home and abroad.

In the application of sewage treatment, a membrane technology and a microbial fermentation technology are combined to form a novel and efficient sewage treatment technology, which is called a Membrane Bioreactor (MBR). MBRs have been widely used at home and abroad. MBRs are mainly flat plate type, hollow fiber type and tubular type, wherein hollow fiber curtain type membrane modules are mainly used.

At present, there are two main packaging methods for hollow fiber curtain type membrane modules: (1) firstly, packaging and cutting a certain amount of hollow fiber membrane filaments, then inserting the hollow fiber membrane filaments into an MBR water collecting pipe, and then bonding the hollow fiber membrane filaments by adopting soft rubber such as polyurethane and the like; (2) a certain amount of hollow fiber membrane filaments are packaged on the upper half part of the MBR water collecting pipe, and after cutting is completed, the upper part and the lower part of the MBR water collecting pipe are bonded together by glue to form the complete MBR water collecting pipe. Obviously, in both methods, the curtain-type membrane assembly is cast by using the inner shell and the outer shell, the operation is complicated, and the production efficiency is low.

Therefore, it is a necessary way to develop MBR technology to select a hollow fiber curtain membrane module packaging method with simple and efficient operation. ZL201310436489.2 discloses a packaging method of a hollow fiber curtain type membrane module, which comprises the following steps: (1) hanging a plurality of hollow fiber membrane filaments with consistent lengths on an end socket tool rack according to a known method, and cutting off redundant membrane filaments; (2) stretching the hollow fiber membrane filaments into an MBR water collecting pipe, and sequentially adding the packaging material, the hard glue and the soft glue; (3) and (3) after the glue is completely hardened, rotating the end socket tool rack, repeating the working procedures (1) and (2), and then packaging the other end of the hollow fiber membrane wire. The invention completes the encapsulation of hard glue and soft glue in the MBR water collecting pipe, simplifies the encapsulation process, and has better sealing and higher strength of the membrane component. 201610798663.1 discloses a curtain-type membrane element one-time casting molding manufacturing process, which comprises the following steps: (1) smoothing the membrane filaments without crossing up and down, and then clamping the membrane filaments front and back by using 2 plastic plates made of ABS materials; (2) after the membrane filaments are fixed, adding a proper amount of filler into the water collecting box; (3) putting the membrane filaments into a water collecting box, and injecting bi-component polyurethane glue; after one end is poured, the other end is poured in a turning mode; and after the two ends are poured, the membrane element is manufactured. The above two patents solve the key technical problem of one-step casting molding of curtain-type membrane components, but do not describe the structure of the water collecting pipe, the arrangement of membrane filaments, etc. in detail. ZL201721273102.6 discloses a membrane shell for curtain-type membrane, this membrane shell includes water catch bowl and inside groove, the water catch bowl both ends are equipped with the outlet pipe, a plurality of membrane groove units are set to the inside groove components of a whole that can function independently, and the membrane groove unit inlays in proper order along water catch bowl length direction and locates in the water catch bowl, and the dovetail has been seted up along its direction of height to the membrane groove unit inner wall, along its fixed reinforcing plate that is provided with of width direction, has made things convenient for the cutting of inside groove and membrane silk, reduces cutting error to improve cutting efficiency, also reduced the probability that the membrane groove unit leaked simultaneously. However, the inner tank of the membrane shell has a complicated structure, and is difficult to be practically used.
