Description
Technical Field

Background
Microbial fuel cells (Microbial Fuel Cell, MFC) are a new method for generating electrical energy-the use of bacteria to generate bioelectric energy from biomass is a technology that can directly convert chemical energy in organics in wastewater into electrical energy under the action of microorganisms. In the prior art, microbial fuel cells are used for industrial and urban sewage treatment, particularly, combined with a biological floating island technology, as disclosed in patent document 1 (CN 109879402 a), bioelectrochemical devices and methods for coupling and purifying bottom sludge of an aquaculture pond with a water body are disclosed, wherein a floating bed is arranged as a bioelectrochemical cathode, a biochemical anode is arranged in the bottom sludge of the aquaculture pond, the bioelectrochemical anode and the bioelectrochemical cathode are connected through a wire, so that not only can the water body be purified, but also the sludge can be purified, but the device cannot automatically move to a new bottom sludge area to be treated after the sludge is purified, the anode is required to be manually or manually pulled up and reinserted, and the bioelectrochemical anode is rearranged, so that besides the labor intensity is increased, the time cost for rearrangement is also increased, and longer domestication time is required when the bioelectrochemical cell is restarted, further, the completeness of the anode cannot be ensured even after the anode is pulled up due to the fact that the suction force of the sludge is large, and the bioelectrochemical cathode inserted into the bottom is connected through the wire 3, and the floating bed is not always positioned. As another example, patent document 2 (CN 115286120 a) discloses an electrode artificial ecological floating island device and a method for synchronously repairing water and bottom mud, which is characterized in that a telescopic fixed bracket is arranged between a floating body and an anode material, and the floating body can adaptively float up and down along with the change of water level by arranging the fixed bracket, but the floating body is not considered to be automatically arranged at other positions after the bottom mud is purified, and the anode is horizontally arranged, so that the difficulty that the anode automatically moves to other positions after the bottom mud is purified at a certain position is increased; finally, for the study of the microbial fuel cell, patent document 3 (WO 2022/237837 A1) has studied that the voltage of the microbial fuel cell is in a certain relationship with the concentration of organic matters in the sewage, and whether the sewage is completely treated can be monitored by monitoring the voltage value at the connected resistor.
In summary, in the prior art, the ecological floating island coupled microbial fuel cell is only considered to perform sewage treatment on a fixed position, the problem that the sewage needs to be moved after the sewage is purified is not considered, the sewage treatment equipment is only moved in a common manual mode even though the sewage needs to be moved after the sewage is purified, the microbial fuel cell sewage treatment equipment capable of automatically moving according to the sewage treatment condition is not formed, the air bag is not applied to the anode of the microbial fuel cell so as to facilitate the anode to be pulled out, and the original acclimatized adaptive microbial groups in the anode are maintained.
