Embodiment

[0055] A curtain-type hollow fiber membrane encapsulation method is carried out according to the following steps: (1) cut the hollow fiber membrane wires into uniform lengths according to a known method, and tighten the two ends with cable ties; (2) insert the hollow fiber membrane bundle into a uniform distribution plate In the hole; the uniformly distributed plate with the hollow fiber membrane bundle is immersed in the gelatin solution, that is, the water outlet hole of the hollow fiber membrane bundle is immersed, and the water outlet hole is immersed in the gelatin solution for 5 minutes, and then cured for 30 minutes; (3) The evenly distributed plate with hollow fiber membrane bundles stretches into the raised steps of the MBR water collection pipe; (4) add X (weight) polyurethane glue between the MBR water collection pipe and the hollow fiber membrane bundles; (5) let it stand for X hours After the glue is completely hardened, rotate 180°, and repeat steps (1)(2)(3)(4) t...

Abstract

The invention relates to a sealing method for a curtain type hollow fiber membrane and belongs to the field of water treatment. The sealing method comprises the following steps: fastening one end of a hollow fiber membrane bundle; soaking the fastened end of the hollow fiber membrane bundle with a blocking matter, taking out the hollow fiber membrane bundle and curing the same; inserting one end of the cured hollow fiber membrane bundle into an MBR water collecting tube correspondingly, and bonding and fixing the two; and manufacturing the other end of the hollow fiber membrane. The method comprises the following steps: fastening two ends of the hollow fiber membrane bundle; soaking the two fastened ends of the hollow fiber membrane bundle with a blockage matter, taking out the hollow fiber membrane bundle and curing the same; and inserting two ends of the cured hollow fiber membrane bundle into MBR water collecting tubes correspondingly, and bonding and fixing the two. According to the sealing method provided by the invention, the tail end of the membrane silk does not need to extend into the water collecting tubes, so that the utilization ratio of the membrane silk is increased; the water yield end does not need to be cut, so that solid wastes are not generated; the packaging matter can be dissolved in water, and only needs to be dissolved out with water after the hollow fiber curtain type membrane is manufactured, and the dissolved-out package matter can be recycled.

Description

technical field [0001] The invention relates to a glue sealing method for a curtain-type hollow fiber membrane, which belongs to the field of water treatment. Background technique [0002] Membrane separation is a new separation technology that appeared in the early 20th century and rose rapidly after the 1960s. Membrane separation technology has been widely used in food, medicine, biology, environmental protection, Chemical industry, metallurgy, energy, petroleum, water treatment, electronics, bionics and other fields. [0003] Membrane-bioreactor (MBR) is a new type of wastewater treatment system that combines membrane separation technology and biological treatment technology. It uses ultrafiltration or microfiltration membrane modules to replace the sedimentation tank in the traditional activated sludge method to achieve mud-water separation. The hollow fiber curtain membrane module involved in this patent is the core component of the membrane-bioreactor (MBR). The perf...
