Example Embodiment
[0036] Example one:
[0037] A device for monitoring organic pollution of groundwater based on a microbial fuel cell in this embodiment, refer to figure 1 , Including the device body 1, the water inlet pipe 2 communicating with the device body 1, and the battery device placed in the device body 1;
[0038] The device body 1 is used to place the electrodes and wires of the battery device in the device body 1. The device body 1 protects the battery device. The electrodes will not be unstable due to the impact of objective factors such as rapids; Water pipe 2, put one end of the water inlet pipe 2 in the groundwater, and the other end of the water inlet pipe 2 is connected to the device body 1. A peristaltic pump 8 is provided on the water inlet pipe 2, and the groundwater in the device body 1 can be continuously replaced in real time through the peristaltic pump 8 , Complete real-time in-situ monitoring;
[0039] The battery device includes an anode chamber 4 and a cathode chamber 5 c...
Example Embodiment
[0042] Embodiment two:
[0043] This embodiment is a device for monitoring organic pollution of groundwater based on a microbial fuel cell. Based on the first embodiment, an overflow weir 7 is provided on the outside of the top of the device body 1. When the peristaltic pump 8 on the water inlet pipe 2 is used as the device body 1 When the groundwater is continuously replaced, when the groundwater overflows the top of the device body 1, the groundwater can be discharged through the overflow weir 7, which ensures that the groundwater in the device body 1 will not affect the working stability of the battery device due to overfilling.
Example Embodiment
[0044] Embodiment three:
[0045] In this embodiment, a device for monitoring organic pollution of groundwater based on a microbial fuel cell. Based on the second embodiment, in order to further improve the current monitoring accuracy, the resistance value of the external resistor 9 is set to be between 50-100Ω, and the anode chamber 4 and The cathode chamber 5 uses graphite felt with a thickness of 10-20 mm as the electrode material. In order to prevent the electrode material from being corroded in groundwater and bottom mud, the graphite felt is covered with stainless steel mesh; the current monitoring device 6 includes data The data logger monitors the current passing through the external resistance.
