Example Embodiment
[0034] Embodiment 1: The preparation method of pig manure activated carbon electrode material in this embodiment is carried out according to the following steps:
[0035] Step 1. Pre-treatment: add 1mol / L hydrochloric acid solution to the dried pig manure, immerse for 1.5h at room temperature, then wash with deionized water to neutrality, and dry it at 100°C to constant weight;
[0036] Step 2. Then place it in a pyrolysis furnace, pyrolyze it at high temperature under a nitrogen atmosphere at 500°C for 0.5h, and cool it down to room temperature with the furnace to obtain pyrolysis charcoal, marked as PMB;
[0037] Step 3. Add 100ml of water and alkali-carbon mass ratio of 4:1 according to 10g pyrolysis charcoal. Add KOH solution to the pyrolysis charcoal obtained in step 2, mix well, immerse for 24h, and dry at 100℃ to constant weight ;
[0038] Step 4. Then, under the protection of nitrogen, activate at 800℃ for 1.5h at high temperature, and then cool to room temperature;
