Embodiment 1
[0032] This embodiment provides a device for coupling an electrochemical system to sulfur autotrophic denitrification, see figure 1 As shown, the device for coupling the electrochemical system to sulfur autotrophic denitrification includes a reactor 1, an electrochemical assembly 2 and sulfur particles 3, wherein: the reactor 1 includes a water inlet 11 and a water outlet 12; the electrochemical assembly 2 is arranged in the reaction In the device 1, the electrochemical component 2 includes an anode 21 and a cathode 22. The material of the anode 21 is carbon, and the material of the cathode 22 is conductive metal; the surface of the cathode 22 is enriched with autotrophic denitrifying functional bacteria; sulfur particles 3 are filled in the electrochemical In component 2; the surface of sulfur particle 3 is enriched with autotrophic denitrifying functional bacteria.
[0033] In the electrochemical system coupled sulfur autotrophic denitrification device provided in this examp...
Embodiment 2
[0049] On the basis of Example 1, the shape of the cathode 22 of the electrochemical component 2 in the device for coupling the electrochemical system to sulfur autotrophic denitrification provided in this example is a mesh structure.
[0050] The cathode 22 is designed as a mesh structure, on the one hand, it is beneficial to increase the surface area of the cathode 22, so that more autotrophic denitrification functional bacteria are enriched on the surface of the cathode 22; The autotrophic denitrification functional bacteria enriched on the wells are fully exposed, thereby improving the treatment capacity of nitrate in the sewage by the hydrogen autotrophic denitrification method; and because the hydrogen autotrophic denitrification method will consume sulfur during the reaction H produced during + , so as to further promote the sulfur autotrophic denitrification reaction, so that the electrochemical system coupled sulfur autotrophic denitrification device can achieve eff...
Embodiment 3
[0065] On the basis of Example 2, the reactor 1 in the electrochemical system coupled sulfur autotrophic denitrification device provided in this example is an upflow reactor.
[0066] The reactor 1 is designed as an upflow reactor, so that the water to be treated enters from the lower part of the reactor 1, and the treated water flows out from the upper part of the reactor 1; the upflow reactor is selected as the reactor 1, which is conducive to filling Throughout the reactor 1, the water entering the reactor 1 needs to move from the bottom to the top of the reactor 1 before it can flow out from the water outlet 12, so as to ensure that the water is fully in contact with the electrochemical components 2 and the sulfur particles 3 in the reactor 1, ensuring The reaction is fully carried out, thereby promoting the denitrification effect of the method of coupling sulfur autotrophic denitrification with the electrochemical system.
[0067] In order to further increase the sufficie...
