Problems solved by technology

[0004] Membrane fouling often occurs during the application of the existing MBR technology. The traditional method is to use aeration to control membrane fouling, but a large amount of aeration will lead to an increase in water treatment costs, and will also cause hair to clog the membrane modules. Roots, to a certain extent, require regular online cleaning and offline cleaning of membrane components, which consumes a lot of labor costs and time

Abstract

The invention provides an MBR membrane pool structure and a transmission system enabling an MBR membrane assembly to do reciprocating movement. The MBR membrane pool structure comprises an upper part pool interval, a middle part pool interval and a lower part pool interval, wherein a plurality of MBR membrane elements are arranged in the upper part pool interval; a sludge separation component is arranged in the middle part pool interval; a sludge settling component and a backflow sludge discharging pipe are arranged in the lower part pool interval. The transmission system comprises an MBR membrane pool structure and a transmission device based on double-arm output; a rail, a rolling wheel and a variable-frequency motor in the transmission device drive the MBR membrane assembly to do reciprocating movement. The position limiting wheels are arranged at two sides or one side of the rail; the moving range and the deviation direction of the slide frame are limited through the position limiting wheels. The MBR membrane pool structure provided by the invention has the advantages that an MBR membrane assembly device can be positioned in the upper layer low-sludge-concentration region; the membrane pollution speed can be favorably decelerated; a double-arm output transmission structure is used; great-power conduction can be realized; the operation stability is improved; through the position limiting wheel, the abrasion of the rail and the sliding wheel can be reduced; the long-time operation deviation of the rail is avoided.
