Example Embodiment
[0035] Example one
[0036] figure 1 It is a schematic diagram of the structure of the electrochemical membrane biological sewage processor provided in the first embodiment of the present invention. See figure 1 , The electrochemical membrane biological sewage processor includes: a treatment tank 11, arranged in the treatment tank 11 along a first direction ( figure 1 In the X axis direction), the first electrode 12, the sacrificial electrode 13 and the second electrode 14, the membrane module 15 and the power supply module 16 arranged in the processing cell 11 are arranged in sequence. Among them, 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 arranged between the first electrode 12 and the sacrificial electrode 13, and the membrane assembly 15 is also arranged between the sacrificial electrode 13 and the second electrode 14. The power supply module 16 is electrically connected...
Example Embodiment
[0046] Example two
[0047] image 3 It is a schematic diagram of the structure of the electrochemical membrane biological sewage processor provided in the second embodiment. Compared with the first embodiment, this embodiment also includes an aeration module. Specifically, see image 3 In the electrochemical membrane biological sewage processor, the aeration module 17 includes an air duct 171 and an air conveying unit 172. One end of the air pipe 171 is connected with the gas output end of the gas delivery unit 172, and the other end extends into the processing tank 11. By installing the aeration module 17 in the electrochemical membrane biological sewage treatment system, the liquid in the treatment tank 11 can be disturbed under the action of the airflow and the dissolved oxygen in the treatment tank 11 can be increased, which is not only beneficial to make the treatment tank The liquid fully undergoes an electric flocculation reaction, and the liquid in the treatment tank...
