Embodiment 1

[0031] figure 1 It is a schematic structural diagram of the electric field enhanced membrane biological sewage treatment device provided in Embodiment 1 of the present invention. see figure 1 , the electric field enhanced membrane biological sewage treatment includes: a treatment pool 11, arranged in the treatment pool 11 along the first direction ( figure 1 The anode 12 , the cathode 14 , the membrane module 15 and the power supply module 16 arranged in the treatment pool 11 are arranged in sequence in the X-axis direction). Wherein, the anode 12 is an oxygen evolution electrode. The membrane module 15 is arranged between the anode 12 and the cathode 14 . The power supply module 16 is electrically connected to both the anode 12 and the cathode 14 to form a potential difference between the anode 12 and the cathode 14 .

[0032] The technical solution of this embodiment is provided in the processing pool 11 along the first direction ( figure 1 The anode 12 and the cathode ...

Embodiment 2

[0042] figure 2 Schematic diagram of the structure of the electric field-enhanced membrane biological sewage treatment device provided in Example 2. Compared with the first embodiment, this embodiment also includes an aeration module. Specifically, see figure 2 , in the electric field enhanced membrane biological sewage treatment unit, the aeration module 17 includes an air duct 171 and an air delivery unit 172 . One end of the air duct 171 is connected to the gas output end of the gas delivery unit 172 , and the other end extends into the processing tank 11 . By arranging the aeration module 17 in the electric field enhanced membrane biological sewage processor, under the action of the air flow, the liquid in the treatment tank 11 can be disturbed and the dissolved oxygen in the treatment tank 11 can be increased, which is not only beneficial to promote the flow of water in the treatment tank The liquid is in full contact with microorganisms to improve the efficiency of ...

Abstract

The embodiment of the invention discloses an electric field enhanced membrane biological sewage disposal machine. The electric field enhanced membrane biological sewage disposal machine comprises a disposal pool, an anode and a cathode arranged in the disposal pool and sequentially arranged in the first direction, a membrane assembly arranged in the disposal pool and between the anode and the cathode and a power supply module, wherein the anode is an oxygen evolution electrode, and the power supply module is electrically connected with the anode and the cathode. Compared with an existing sewage disposal device, the electric field enhanced membrane biological sewage disposal machine can improve the water quality of the disposed sewage and improve membrane pollution simultaneously.

Description

technical field [0001] Embodiments of the present invention relate to drinking water or sewage treatment technology, in particular to an electric field enhanced membrane biological sewage treatment device. Background technique [0002] Domestic sewage is the sewage produced in the process of human production, and it is the main source of pollution of water bodies. It mainly includes feces and washing sewage. With the rapid development of social economy and the increase of population, the discharge of domestic sewage is increasing, which has become a serious obstacle to economic development and the improvement of people's quality of life. People are facing the severe test of double water shortage of resources and water quality. [0003] Membrane bioreactor (MBR), as a sewage treatment technology that organically combines membrane separation and biotechnology, has the advantages of good effluent quality, high system treatment efficiency, high load rate, compact structure, smal...
