[0020] The present invention will be described in further detail below through specific examples. The following examples are only descriptive and not restrictive, and cannot limit the protection scope of the present invention.
[0021] A rotary immersed water treatment ultra-microfiltration method, in which no membrane tube is provided outside the membrane module, so that the membrane filaments are in an open state and directly contact the flowing water to be filtered. The driving device is used to make the membrane module rotate forward and backward in the water to be treated. During the movement, the water flow and the membrane filament are relatively rubbed. Because the surface of the membrane filament is washed by the water flow (tangential force), the dirt on the membrane filament surface is taken away in time .
[0022] A rotary submerged water treatment ultra-microfiltration device includes a plurality of membrane filaments 3, membrane filament discs 2, 4, a component chassi...
