Problems solved by technology

[0003] In view of the above-mentioned roll-type membrane bioreactor currently used, the integrated membrane module is placed inside the reactor, because the integrated design allows sludge and various microorganisms to easily adhere to the surface of the membrane or enter the interior of the membrane pores to block the membrane pores. However, the problem that the water permeability decreases and the membrane module is polluted, the invention provides a roll-type membrane bioreactor

Embodiment 1

[0028] like Figure 1-Figure 5 As shown, the present invention provides a roll-type membrane bioreactor, the structure of which includes an interface 1, a mold base upper seal 2, a mold base 3, a mold base lower seal 4, a water pump 5, a water outlet 6, a water collection pipe 7, and a membrane module 8. The blower 9, the water inlet 10, and the aeration device 11, the interface 1 is provided with a sealing ring and the upper seal 2 of the mold base, and the lower seal 4 of the mold base are sealed and blocked, and the inside of the mold base 3 is provided with an outlet Water inlet 6, water collection pipe 7, membrane module 8, water inlet 10 and aeration device 11, described water collection pipe 7 is connected with water pump 5, and described aeration device 11 is composed of blower 9, main aeration port 11a, auxiliary aeration port 11b, an aeration disc 11c is formed, the blower 9 is connected to the aeration disc 11c, and the main aeration port 11a and the auxiliary aerat...

Embodiment 2

[0030] like Image 6 As shown, the membrane assembly 8 includes a membrane element 81, a connecting frame 82, a mounting seat 83, and an extrusion seat 84. The membrane elements 81 are distributed in parallel, and the membrane element 81 is fixed on the extrusion seat 84 by a connecting frame 82. , and the two sides of the extrusion seat 84 are installed and fixed with the mounting seat 83, the connecting frame 82 is wave-shaped, and the membrane elements 81 are installed independently, and the airflow generated by the air distribution hole b3 acts on the membrane surface of the membrane element 81 , one end of the blocking member b0 extending out of the aeration disc 11c is connected to the extruding seat 84 with a tie rod, and the connecting frame 82 is wave-shaped, and the connecting frame 82 is symmetrically arranged, and can be aerated at the auxiliary aeration port 11b The radial impact forces generated during the process cancel each other out to a certain extent, ensuri...

Abstract

The invention discloses a spiral-wound membrane bioreactor, which structurally comprises an interface, a mold frame upper seal port, a mold frame, a mold frame lower seal port, a water pump, a water outlet, a water collecting pipe, a membrane assembly, an air blower, a water inlet and an aeration device, wherein a sealing ring is arranged in the interface and forms sealing plugging with the mold frame upper sealing port and the mold frame lower sealing port, the water outlet, the water collecting pipe, the membrane assembly, the water inlet and the aeration device are arranged in the mold frame, the water collecting pipe is connected with the water pump, and the aeration device is composed of the air blower, a main aeration port, auxiliary aeration ports and an aeration disc. According tothe invention, when the membrane surface of the membrane assembly is polluted, the membrane flux is reduced and even the gaps of the membrane elements are blocked, a large amount of pollutants are accumulated on the surface of the membrane to cause the increase of the weight of the membrane element, an extrusion seat is compressed due to the large weight of the membrane element, the extrusion seatis pressed downwards to push a pull rod away so as to open the auxiliary aeration ports in the two sides, the auxiliary aeration ports are jet-type and synchronously focus on acting in the membrane pores in the surface of the membrane, and the impact pressure generated by jetting enables the attachments on the surface of the membrane to fall off, so that the membrane flux is improved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a roll-type membrane bioreactor. Background technique [0002] Membrane bioreactor is also MBR process, which is mainly a new type of wastewater treatment process formed by combining activated sludge method and separation technology. It generally consists of three parts: membrane module, bioreactor and pump. It is composed of membrane module A biochemical reaction system combined with a bioreactor. This system uses the reaction matrix in the sanitation area to carry out biotransformation and at the same time separates the reaction product and intercepts the organism through the membrane module. The effluent quality after its treatment can meet the most stringent requirements in the world. Sewage discharge standards, or even stricter discharge requirements in the future, the roll-type membrane bioreactor currently used, the one-piece membrane module is placed inside the re...
