Embodiment 1

[0046] When the existing MBR membrane packer uses off-line membrane washing in the integrated membrane box, it needs to be hoisted out as a whole for cleaning or manually removed from the tank for cleaning. It also consumes manpower and operates in a limited space throughout the process, and there are certain safety hazards. Furthermore, according to the disassembly requirements of the existing MBR membrane assembly, a distance of a membrane is reserved in the box body during design and manufacture, which occupies the volume of the box body, so that the volume and weight of the box body increase accordingly. , the hoisting difficulty increases. In order to solve the problems existing in the prior art, the present application provides a convenient detachable MBR membrane stacker, so as to reduce the cleaning difficulty of the MBR membrane stacker and solve the problem of time-consuming and laborious overall hoisting.

Embodiment 2

[0057] This embodiment of the present application provides a method for disassembling and washing the easily disassembled MBR membrane assembly provided in the first embodiment. The method can be briefly described as follows:

[0058] see figure 1 , remove the limit structure 2 on the frame assembly 1, and remove the water collection pipeline 4 connected with the membrane group 3, so that one end of the several diaphragms 31 constituting the membrane group 3 is self-limiting installation groove 24 of the limit structure 2 To disengage from the inside, the diaphragm 31 is pulled out from the frame assembly 1. After the diaphragm 31 is cleaned, the diaphragm 31 is inserted back to its original position and the dismantled limiting structure 2 is put back in its original position.

[0059] Compared with the existing MBR membrane stacker, which needs to be hoisted as a whole or disassembled in the lower tank when washing the membrane off-line in the integrated membrane box, the MB...

Embodiment 3

[0062] The embodiments of the present application provide a water treatment device. The water treatment device includes a biological reaction tank and an MBR membrane packager installed in the biological reaction tank, and the MBR membrane packager is the easily disassembled MBR membrane packager provided in the first embodiment. The biological reaction tank contains sewage to be treated, and the detachable MBR membrane unit filters the sewage to be treated through the membrane unit 3 on it to obtain clean water, and the filtered clean water is output from the water collection pipeline 4 of the detachable MBR membrane unit. The detachable MBR membrane unit realizes the scouring of the sludge on the membrane unit 3 through the aeration device 5 on it.

Abstract

The invention discloses a conveniently-disassembled MBR (Membrane Biological Reactor) membrane module device, a disassembling and washing method, a water treatment device and a treatment method. The MBR membrane module device comprises a frame assembly, and a membrane module, a water collecting pipeline and an aeration device which are respectively arranged on the frame assembly, the membrane group comprises a plurality of membranes which are adjacently arranged at intervals, one or more water outlet ports are formed in each membrane, and each water outlet port is detachably connected with the water collecting pipeline; the aeration device comprises an aeration pipeline and a plurality of aeration tanks connected with the aeration pipeline; a limiting structure is arranged on the frame assembly, the limiting structure is detachably connected with the frame assembly, a plurality of limiting mounting grooves matched with the diaphragms are formed in the limiting structure, and the diaphragms are inserted into the limiting mounting grooves. The MBR membrane module device provided by the invention is simple and convenient to disassemble, a single membrane can be pulled away and cleaned, the membrane is inserted back to the original position after being cleaned, and a limiting structure is mounted, so that the problems that the whole MBR membrane module device is inconvenient to hoist in the cleaning process, and the cleaning is time-consuming and labor-consuming are solved.

Description

technical field [0001] The present application relates to the technical field of water treatment devices, and in particular, to a portable MBR membrane packer and its disassembly and cleaning method, a water treatment device and a treatment method. Background technique [0002] Membrane Bioreactor (MBR) technology is a combination of biological reaction and membrane separation technology, using membrane as a separation medium to replace conventional gravity precipitation solid-liquid separation to obtain effluent, and can change the reaction process and improve the reaction efficiency. Sewage treatment method. MBR membrane packer is a basic water treatment unit assembled by membrane module, gas distribution device, water collection device, frame, etc. It is placed in the biological reaction tank for solid-liquid separation. MBR is a new type of sewage treatment technology, which replaces the secondary sedimentation tank with membrane separation (the function of the secondar...
