Embodiment 1
[0037] Such as figure 1 As shown, a device for removing polychlorinated biphenyls in sediment using a microbial electrolytic cell in this embodiment consists of a dual-chamber microbial electrolytic cell and an electrochemical workstation. The dual-chamber microbial electrolytic cell includes an anode chamber 1 and a cathode chamber 2, The anode chamber and the cathode chamber are separated by a cation exchange membrane 3, the anode chamber is provided with the battery anode liquid inlet 5, the anode electrode 6 and the reference electrode 7, the cathode chamber is provided with the battery cathode liquid inlet 8 and the cathode electrode 9, the anode electrode, The reference electrode and the cathode electrode are connected to the electrochemical workstation 4 through an external circuit 10, and the electrochemical workstation constantly controls the anode to maintain a potential of +0.2V.
[0038] The device of this embodiment is used to remove polychlorinated biphenyls in t...
Embodiment 2
[0042] Compared with Example 1, the device and method for removing polychlorinated biphenyls in sediment by using a microbial electrolytic cell in this example is different in that 1ml of sodium acetate with a concentration of 1M is not added regularly, and the rest are identical.
