The Membrane Bioreactor (MBR) is a high-efficiency wastewater treatment system organically combining the traditional biological treatment technology and the membrane separation technology, and compared with the traditional biological treatment technology, the MBR has the advantages of stable and high-quality effluent, easiness in automatic control, small occupied area and the like. At present, MBR hollow fiber membrane is generally for taking the lining membrane silk, and the lining crochet support pipe can reduce the membrane silk production degree of difficulty, increases the mechanical strength of membrane silk, makes follow-up product form modular structure more easily. In the production and manufacturing process of the crochet support tube, the quality of the crochet support tube can be improved through post-treatment, and the following problems in the production process can be optimized:

in the manufacturing process of the MBR membrane yarn lining crocheting support tube, the crocheting support tube is easy to have uneven meshes, namely the pitch of each crocheting support tube is different, so that the bubble point of the finished product membrane yarn is low and the flux is too large, the membrane yarn is easy to break and the pollution of a sludge gel layer is formed in the serious cases.

MBR membrane silk inside lining crocheted stay tube raw and other materials are the dacron low stretch yarn, and the high fine number dacron low stretch yarn of high denier number easily has broken yarn, and the weaving has the yarn to collude disconnected phenomenon for the crocheted stay tube and takes place, and then causes the burr of crocheted stay tube, and the burr can influence the film thickness and the flux of finished product membrane silk, causes the flux attenuation of membrane silk.
