Embodiment Construction
[0011] The present invention will be further described below using the accompanying drawings and examples.
[0012] refer to figure 1 , The sewage recycling high-performance polyethersulfone separation membrane of the present invention is composed of several hollow fiber bundles juxtaposed vertically to form bundles. In one hollow fiber, A3 is the inner wall layer of the hollow fiber, A2 is the dense layer of the hollow fiber, and A1 is the outer wall layer of the hollow fiber.
[0013] refer to figure 2 , the device with the polyethersulfone separation membrane of the present invention includes a housing 6, the housing 6 is fixed in sequence by the upper housing 6-1, the middle housing 6-2 and the lower housing 6-3, and its connection is by means of Non-toxic adhesive bonding. The housing 6 is provided with a polyethersulfone separation membrane 7, and the two ends of the polyethersulfone separation membrane 7 are fixedly connected with the mouth of the upper housing 6-1 ...
