[0002] Biogas-producing organisms primarily involve the microorganisms involved in the biogas fermentation process. These microorganisms, working anaerobic (without oxygen), decompose and transform various organic materials (such as human and animal feces, straw, and sewage), ultimately producing biogas. To effectively increase the usability of biogas and minimize environmental pollution caused by biogas-producing organisms, desulfurization equipment is used to treat biogas-producing organisms.

[0003] During operation, the desulfurization device washes the biogas with an alkaline solution to absorb the sulfide compounds within it, thereby treating the sulfide compounds. However, existing desulfurization devices, which only use a single water-washing component to biodesulfurize the biogas, cannot effectively guarantee the desulfurization effect of the device. Moreover, impurities within the biogas during feeding can easily affect the desulfurization process. Therefore, a biogas biological desulfurization device is proposed to address the above problems.

[0021] Furthermore, the activated carbon plate 11 forms a locking limit structure with the desulfurization body 2 through the fixing plate 12 and the rubber pad, and the fixing plate 12 forms a spiral locking structure with the desulfurization body 2 through the first bolt 13, so that the spirally installed activated carbon plate 11 and other components facilitate the filtering of the biogas organisms in the desulfurization body 2, so that the sulfide substances inside the biogas organisms can be further adsorbed by the activated carbon plate 11.

This is the use process of the biogas biological desulfurization equipment.
