[0108] FIG. 9 is a flowchart illustrating a process method using an immersion-type bioelectrochemical reactor equipped with an electrode module according to one embodiment of the present invention.

[0109] Referring to FIG. 9, a process method using an immersion-type bioelectrochemical reactor according to one embodiment of the present invention feeds a composition produced through a fermentation process of food waste in step S210.

[0110] Specifically, a composition can be prepared by performing a floating matter removal operation on the anaerobic tank sludge and then performing a fermentation process.

[0111] After adding the composition, assemble the reactor tank and cover, connect the N2 line, and connect the reference electrode, pH, H2 sensor, and power supply.

[0112] Afterwards, in step S220, the pump module for feed circulation inside the reactor is operated.

[0113] In step S230, nitrogen is supplied into the reactor to create an anaerobic environment.

[0114] In steps S220 to S230, the Tubing pump can be operated and the N2MFC operated to purge at 2000 CC / min for 2 hours.

[0115] In step S240, an external voltage is applied to the electrode module.

[0116] Specifically, the working anode voltage can be set in the power supply program.

[0117] In step S250, hydrogen produced inside the reactor is captured.

[0118] In addition, the change in pH inside the reactor and the hydrogen production amount can be measured in step S260.

[0119] In step S260, experimental data can be monitored in real time to identify anomalies and progress.

[0120] Meanwhile, prior to step S210, the anion exchange membrane in step S110 may be immersed in a buffer solution for a preset time.

[0121] In step S120, the graphite felt layer can be immersed in a hydrochloric acid solution for a preset time.

[0122] To explain in detail, the first step involves constructing an H-type bioelectrochemical reactor for seed culture.

[0123] Since it is advantageous to apply secondary digestion sludge after optimizing the electroactive microbial community through pre-culture rather than applying it directly to an immersed bioelectrochemical reactor in a state where various microorganisms are supersaturated, a reaction capacity of 900 ml to 1 L is established.

[0124] In the past, pre-culture was carried out by constructing a scale of 250 to 300 ml, but according to one embodiment of the present invention, the capacity of the feed can be increased as the scale increases.

[0125] Afterwards, electrode module assembly and leak testing are performed.

[0126] First, the membrane can be soaked in 0.1 x PBS buffer one day before assembly.

[0127] Since the membrane absorbs moisture and undergoes swelling, it must be allowed to react sufficiently overnight to prevent the possibility of leakage.

[0128] In addition, the graphite felt is soaked in 5% HCl one day before assembly and then washed with 3rd distilled water, and reacting the graphite felt with HCl can create an environment where microorganisms can adhere better to the electrode surface.

[0129] Subsequently, the outer frame, stainless steel mesh, graphite felt, stainless steel mesh, silicon gasket, membrane, silicon gasket, inner frame, and stainless steel wool are added and assembled in reverse order, and wing bolts / nuts are assembled during assembly.

[0130] To conduct a leak test, there are two methods to perform the leak test.

[0131] First, a catholyte is placed inside the assembled electrode module and left overnight to check for any leaks.

[0132] At this time, since the stainless steel wool cathode absorbs some catholyte, fill it to the maximum and then refill the catholyte after 10 minutes.

[0133] In addition, after the assembled electrode module is immersed in 3rd distilled water, a leak test is performed by introducing air into the electrode module using a line that collects H2, and the occurrence of a leak is determined by checking whether bubbles are generated in the electrode module immersed in water.

[0134] In the step of performing H2 and pH sensor calibration, H2 is purged into a plastic beaker containing the sensor for about 15 minutes using a regulator.

[0135] Afterwards, input the settings into the program and mark the points to complete the H2 calibration.

[0136] The pH sensor inputs the set values ​​into the program and completes pH calibration by marking points at pH 4, 8~9.

[0137] FIG. 10 is a graph showing the operation results of an immersed bioelectrochemical reactor equipped with an electrode module according to one embodiment of the present invention.

[0138] Referring to Fig. 10, the maximum oxidation electrode current density >1.5 A / m² 2 It can be confirmed that it can be achieved.

[0139] In addition, it can be confirmed that a maximum hydrogen generation rate of 1.5 L H2 / L / d is achieved.

[0140] In addition, it can be confirmed that 0.02-0.8% of CO2 and 0-0.02% of CH4 are produced.
