Description

Technical Field

[0001] The utility model relates to a flat membrane component, in particular to a novel ultrafiltration flat membrane component, belonging to the technical field of water treatment. Background Art

[0002] In municipal sewage treatment and even in other fields of water environment management, flat membranes have been widely used. The main principle is to use ultrafiltration-grade membranes to separate impurities from clean water in sewage. The ABS plastic plates with flow channels and mobile phone nozzles are widely used in the market. The rigidity is too hard, resulting in the surge force unable to cause the ideal membrane vibration, which hinders the vibration amplitude to be too small, so that more impurities are adsorbed on the surface of the flat membrane, resulting in serious dirt blockage and increased backwashing frequency, which ultimately leads to increased energy consumption and reduced efficiency.

[0003] A Chinese patent publication (publication number: CN202606040U) discloses a flat membrane assembly, including a frame, a group of flat support plates arranged in the frame, a group of filter membranes arranged on both sides of the flat support plates, which are welded to the support plates by ultrasonic or hot-melt welding, and a water collecting pipe is provided at the lower end of the frame; the flat membrane assembly disclosed in the utility model has a simple structure, low energy consumption and good treatment effect; the utility model has too high cost, too large weight and high rigidity, resulting in the surge force being unable to cause ideal diaphragm vibration, hindering the vibration amplitude to be too small, thereby forming more impurities adsorbed on the surface of the flat membrane, forming serious dirt blockage and increasing the backwashing frequency, which ultimately leads to increased energy consumption and reduced efficiency; for this reason, a new type of ultrafiltration flat membrane assembly is proposed.
