Embodiment 1

[0026] Embodiment one, such as figure 1 Shown: there are multiple membrane unit frames, shown as the first membrane frame 2, the second membrane frame 21, the third membrane frame 22, and the fourth membrane frame 23, which are respectively immersed in the water tank 1; The two cantilever ends are respectively connected to the upper ends 12, 24 of the membrane unit 13 and the membrane unit 14 through the rotatable connector 3 to form a balance group; 5 is the gravity balance fulcrum of the balance bar, fixed on the bracket 31; Another balance bar connects the membrane unit 15 and the membrane unit 16 to form another balance group; the two balance groups form a linkage group through the linkage rope 6 and the traction component 7 and the traction motor 8 . The improvements are: cancel the high energy consumption blower configuration of the prior art, and instead set the traction motor, the bracket 31 is vertically fixed in the water tank, can also be installed horizontally on t...

Abstract

The invention discloses an immersed type membrane separation device and an operating method thereof. The device comprises a water tank, a produced water extraction pump, membrane units, membrane frames, a guide wheel and a traction motor, wherein the membrane units are immersed in the water tank, and the produced water extraction pump and the membrane units in the water tank are connected through produced water pipes; every two adjacent membrane units are connected through a balance rod and can perform relative mechanical movement, and by means of a traction component, the traction motor is connected with the balance rods used for connecting the membrane units. According to the operating method, under the action of mechanical traction of the traction motor, upper end parts of a plurality of membrane units perform periodical vertical S-shaped swinging movement, and hollow fiber membrane filaments of the membrane units and water have a mechanical washing effect; the traction motor has low power, low-cost stable operation of a membrane reactor is realized, and the immersed type membrane separation device and the operating method thereof are applied to an aerobic membrane bioreactor, an anaerobic membrane bioreactor and a membrane chemical reactor.

Description

technical field [0001] The invention relates to a submerged membrane separation device and its operation method, in particular to a submerged membrane separation device and its operation method used for membrane pollution control in the membrane separation process. Background technique [0002] The existing membrane bioreactor is the product of the combination of the traditional activated sludge method and the emerging membrane separation technology. It uses the membrane separation module to replace the secondary sedimentation tank in the traditional process, which can not only greatly reduce the floor area, but also The efficiency of solid-liquid separation is significantly improved, and the quality of effluent water is significantly improved. Membrane chemical reactor is the integration of chemical reaction process and membrane separation process, such as the integration of chemical flocculation and membrane separation process in the tap water purification process, or the ...
