[0028] As a preferred embodiment of the above embodiment, a second air inlet pipe 5 is fixedly connected to the outer side of the activated carbon adsorption frame 204 , and a hot air gun 6 is fixedly connected to one end of the second air inlet pipe 5 that passes through the interior of the adsorption tank 203 .

[0031] As a preferred embodiment of the above embodiment, one end of the exhaust pipe 7 is fixedly connected to an air collecting box 8 .

[0032] The specific working principle of this utility model:

[0033] During use, the biogas inside the FRP septic tank is discharged from the exhaust pipe 1, and the biogas enters the filter box 201 through the exhaust pipe 1. Since the filter box 201 contains calcium hydroxide solution, the carbon dioxide and hydrogen sulfide components in the biogas react with the calcium hydroxide solution, and the acidity of hydrogen sulfide is weaker than that of carbon dioxide, so the carbon dioxide first reacts with the calcium hydroxide solution to produce calcium carbonate and water, and the carbon dioxide and hydrogen sulfide components in the biogas are less, so the calcium hydroxide cannot react completely, and then the hydrogen sulfide component in the biogas reacts with the unreacted calcium hydroxide solution to produce calcium sulfide and water, and calcium sulfide is easily hydrolyzed in water, so an equal amount of calcium hydroxide solution and calcium sulfide are produced. Hydrogen gas prevents hydrogen sulfide from reacting and consuming calcium hydroxide solution in the filter box 201, preparing for the next filtering of carbon dioxide. Subsequently, the biogas flows into the adsorption tank 203 through the connecting pipe 202 after the filter box 201, and the activated carbon adsorption rack 204 in the adsorption tank 203 is fixedly connected to the connecting pipe 202, so that the biogas enters the activated carbon adsorption rack 204, and then the activated carbon adsorption rack 204 adsorbs the hydrogen sulfide gas in the biogas through the activated carbon inside, and then the carbon dioxide and hydrogen sulfide gases in the biogas are completely removed, and then the high-purity biogas enters the gas collecting box 8 through the exhaust pipe 7. After the exhaust gas is treated, the drive motor 305 is manually started to make the drive motor 305 drive the fan 304 to rotate. Then, the oxygen tank 303 is opened again to allow the oxygen in the oxygen tube to enter the air intake box 302, and the oxygen that enters is blown into the first air intake pipe 301 by the fan 304, and then the oxygen enters the adsorption tank 203 through the first air intake pipe 301, and the surface of the activated carbon adsorption rack 204 is provided with an air vent 4, so the oxygen that enters enters the activated carbon adsorption rack 204 through the air vent 4, so that the activated carbon in the activated carbon adsorption rack 204 is desorbed, and the oxygen begins to convert the hydrogen sulfide adsorbed inside the activated carbon into monomer sulfur and water, and then the switch of the hot air gun 6 is manually turned on, so that the hot air gun 6 starts to input high-temperature gas to the second air intake pipe 5, and then the high-temperature gas begins to enter the activated carbon adsorption rack 204 through the second air intake pipe 5, so that the monomer sulfur and water desorbed from the activated carbon in the activated carbon adsorption rack 204 are quickly volatilized, so that the activated carbon can continue to be used, and the activated carbon can be desorbed and reused, thereby improving the use efficiency.
