specific Embodiment approach 1
[0020] Specific Embodiment 1: The device of this embodiment that uses waste iron chips and sediment microbial fuel cells to jointly degrade organic matter in sediments includes a container 1, a sealing cover 2, a carbon fiber brush anode 3, a carbon fiber brush cathode 4, and electric energy collection and storage Device 5, surface aerator 6, submersible motor 7, switch 8;
[0021] Wherein the sealing cover 2 is arranged on the top of the container 1;
[0022] The carbon fiber brush anode 3 is placed on the bottom of the container 1, the carbon fiber brush cathode 4 is placed on the top of the container 1, the carbon fiber brush anode 3 is connected to the positive pole of the electric energy collection storage device 5; the carbon fiber brush cathode 4 is connected to the electric energy collection storage device 5 connected to the negative pole;
[0023] The surface aerator 6 is connected with the aeration head 6-1, and the aeration head 6-1 is placed under the carbon fiber...
specific Embodiment approach 2
[0025] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the device also includes an electric energy data collector 9 and a resistor 10, and the electric energy data collector 9 and the resistor 10 are connected in series to the positive and negative terminals of the electric energy collection and storage device 5 top notch. Others are the same as the first embodiment.
[0026] In this embodiment, the electric energy data collector 9 can observe the electricity production situation in real time, and can also judge the mechanical degradation situation through the electricity production situation. Resistor 10 prevents the formation of a short circuit.
specific Embodiment approach 3
[0027] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that the electric energy collection and storage device 5 is a storage battery. Others are the same as those in Embodiment 1 or 2.
