Embodiment 1
[0043] The preparation of the electrocatalytic oxidation catalyst for landfill leachate specifically comprises the following steps:
[0044] (1) Weigh 70% of the alumina powder, 20% of the activated carbon powder, and 10% of the gelling agent in the mass percentage, and the total mass is 100%. Mix the above powders in a cloth bag evenly, then add them to the granulator, roll until the balls have a particle size of 1mm, and the gelling agent is lime powder;
[0045] (2) Put the catalyst carrier after 1mm balling into a sealed bag in step (1) and let it stand for 12h;
[0046] (3) Calcining the catalyst carrier after standing in the step (2) in a kiln at 100°C for 3 hours;
[0047] (4) taking out the carrier after roasting in step (3) and cooling to room temperature;
[0048] (5) Copper nitrate and lanthanum nitrate are respectively prepared into solutions with a mass concentration of 8%, and mixed with ammonium nitrate to obtain a mixed solution, wherein the masses of copper ni...

[0056] A preparation of an electrocatalytic oxidation catalyst for landfill leachate specifically comprises the following steps:
[0057] (1) Weigh 60% of the alumina powder, 30% of the activated carbon powder, and 10% of the gelling agent by weight, and the total mass is 100%. Mix the above powder in a cloth bag evenly, then add it to the granulator, roll until the ball is 2 mm in size, and the gelling agent is cement;
[0058] (2) Put the catalyst carrier after 2mm balling into a sealed bag in step (1) and let it stand for 12h;
[0059] (3) Calcining the catalyst carrier after standing in the step (2) in a kiln at 105° C. for 4 hours;
[0060] (4) taking out the carrier after roasting in step (3) and cooling to room temperature;
[0061] (5) Copper nitrate and lanthanum nitrate are respectively prepared into solutions with a mass concentration of 5%, and mixed with ammonium nitrate to obtain a mixed solution, wherein the masses of copper nitrate and lanthanum nitrate are r...
