Embodiment 1

[0036] figure 1 It is a schematic structural diagram of the electrochemical membrane biological sewage treatment device provided in Embodiment 1 of the present invention. see figure 1 , the electrochemical membrane biological sewage treatment includes: a treatment pool 11, arranged in the treatment pool 11 along the first direction ( figure 1 The first electrode 12 , the sacrificial electrode 13 and the second electrode 14 , the membrane assembly 15 and the power supply module 16 arranged in the processing tank 11 are arranged in sequence in the X-axis direction). Wherein, the activity of the sacrificial electrode 13 is greater than that of the first electrode 12 and the second electrode 14 . The membrane assembly 15 is disposed between the first electrode 12 and the sacrificial electrode 13 , and the membrane assembly 15 is also disposed between the sacrificial electrode 13 and the second electrode 14 . The power supply module 16 is electrically connected to both the first...

Embodiment 2

[0047] image 3 Schematic diagram of the structure of the electrochemical membrane biological sewage treatment device provided in Example 2. Compared with the first embodiment, this embodiment also includes an aeration module. Specifically, see image 3 , in the electrochemical membrane biological sewage treatment device, 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 electrochemical membrane biological sewage processor, the liquid in the treatment tank 11 can be disturbed and the dissolved oxygen in the treatment tank 11 can be increased under the action of the air flow, which is not only beneficial to make the liquid in the treatment tank The liquid fully undergoes electrocoagulation reaction, and promotes the liquid in the treatment tank 11 to fully ...

Abstract

The embodiment of the invention discloses an electrochemical membrane biological sewage treating device. The electrochemical membrane biological sewage treating device comprises a treating pond, a first electrode, a sacrifice electrode, a second electrode, a membrane component and a power supplying module, wherein the first electrode, the sacrifice electrode and the second electrode are arranged in the treating pond along a first direction in sequence; the activity of the sacrifice electrode is larger than the activity of the first electrode and the activity of the second electrode; the membrane component is arranged in the treating pond, and is arranged between the first electrode and the sacrifice electrode and / or between the sacrifice electrode and the second electrode; the power supplying module is electrically connected with the first electrode and the second electrode. Compared with the existing sewage treating device, the electrochemical membrane biological sewage treating device provided by the embodiment of the invention has the advantages that the quality of sewage treated can be improved and the membrane pollution can be reduced simultaneously.

Description

technical field [0001] Embodiments of the present invention relate to drinking water or sewage treatment technology, in particular to an electrochemical 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, small footpr...
