Embodiment 1

[0037] A kind of device of monitoring groundwater organic pollution based on microbial fuel cell of the present embodiment, refer to figure 1 , including a device body 1, a water inlet pipe 2 communicating with the device body 1 and a battery device placed in the device body 1;

[0038] Using the device body 1, the electrodes and wires of the battery device are placed in the device body 1, the device body 1 plays a role in protecting the battery device, and the electrodes will not be unstable due to the influence of objective factors such as rapid currents; Water pipe 2, place one end of the water inlet pipe 2 in groundwater, and the other end of the water inlet pipe 2 communicates with 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 by the peristaltic pump 8 , complete real-time in-situ monitoring;

[0039] The battery device includes an anode chamber 4 and a cat...

Embodiment 2

[0043] A device for monitoring groundwater organic pollution based on microbial fuel cells in this embodiment is based on Embodiment 1. 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 real-time 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.

Embodiment 3

[0045] A device for monitoring groundwater organic pollution based on microbial fuel cells in this embodiment is based on the second embodiment. In order to further improve the monitoring accuracy of the current, the resistance value of the external resistor 9 is set between 50 and 100Ω, and the anode chamber 4 and The cathode chamber 5 all uses graphite felt with a thickness of 10-20mm as the electrode material. In order to prevent the electrode material from being corroded in groundwater and bottom mud, the outside of the graphite felt is covered with a stainless steel mesh; the current monitoring device 6 includes data A recorder, the data recorder monitors the current through the external resistance.

Description

technical field [0001] The invention belongs to the technical field of water environment monitoring, and in particular relates to a device and method for monitoring groundwater organic pollution based on microbial fuel cells. Background technique [0002] Shallow groundwater wells are the main source of drinking water for many rural and peri-urban communities. Shallow wells located in communities where people live are easily drilled, so shallow wells within communities are highly susceptible to fecal contamination or domestic sewage. Therefore, it is very necessary to monitor the water quality of shallow wells in real time, so as to prevent the normal and healthy life of suburban residents from being affected. [0003] The conventional indicators for monitoring the water quality of groundwater include dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD) and nitrogen (N) pollution load. Sampling is carried out in the laboratory, and outdoor rea...
