The inner packaging plate is provided with 300-860 round holes.    USE - Non-woven fabric tube type self-generating dynamic membrane component (C1) used in reactor for intercepting particles and enhancing bio-chemical treatment.    ADVANTAGE - The component (C1) has wide raw material source, easy manufacture, low cost and easy industrial production. The method has no pollution problem. The operation and processing effects are stable.    DETAILED DESCRIPTION - Non-woven fabric tube type self-generating dynamic membrane component (C1) comprises non-woven fabric membrane tube (1), flow guide short pipe (2), membrane shell (3), aeration device (4), inner packaging plate (5), outer packaging plate, lower port, upper port and water connection area. The two ends of membrane shell are sequentially provided with outer packaging plate and inner packaging plate. The outer packaging plate is provided with 180-430 round holes. The inner packaging plate is provided with 300-860 round holes. The non-woven fabric membrane tube is fixed in membrane shell by round holes on inner packaging plate. The flow guide short pipe is fixed between outer packaging plate and inner packaging plate by round holes on outer packaging plate. The upper end of membrane shell between outer packaging plate and inner packaging plate is provided with upper port, where lower end of membrane shell between outer packaging plate and inner packaging plate is water connection area, and arranged with lower port. The bottom of membrane shell is provided with aeration device communicated with flow guide short pipe. INDEPENDENT CLAIMS are included for:    (1) manufacture of the component (C1) which comprises preparing non-woven fabric (60-180 g/m2) having aperture of 10-80 mu m using resin fiber material; coiling non-woven fabric into non-woven fabric membrane tube and flow guide short pipes, flash melting joints or combining by contact agent; molding membrane shell, inner packaging plate and outer packaging plate according to requirements using resin material; filling both ends of membrane shell with inner packaging plate and non-woven fabric membrane tube sequentially, and filling in epoxy resin to seal; and sequentially loading in flow guide short pipes and outer packaging plate, injecting epoxy resin to seal, and mounting lower port, upper port and aeration device; and    (2) use method of the component (C1) which comprises placing the component (C1) into reactor with active sludge; when filtering, air lifting sewage by aeration device, and sewage entering into interior of flow guide short pipes; gradually forming stable dynamic membrane on surface of non-woven fabric membrane tube, where non-woven fabric membrane tube intercepting active sludge flux in mixed solution; backwashing when water out flux is reduced to 60-75% of water in flux, where backwash water and backwash gas enters to interior of component via upper port to rapid wash surface of non-woven fabric membrane tube until large part of dynamic membrane breaks away, and continuing sewage treatment process; and after filtering is ended, backwashing membrane component again.
