| titleOfInvention | Method and device for recovery coupling of biological sulfur and carbon dioxide for producing biogas |
| abstract | The invention relates to the field of environmental engineering and biochemical engineering, in particular to a method and a device for recovery coupling of biological sulfur and carbon dioxide for producing biogas. The method comprises the following steps of (1) using an alkali absorption liquid to absorb hydrogen sulfide and converting hydrogen sulfide into sulfide after coarse methane is subjected to dust removing treatment, using sulfur-oxidizing bacteria to oxidizing the sulfide into elemental sulfur, separating the elemental sulfur and mother solution, adjusting pH of the mother solution to be alkaline mother solution for absorbing the hydrogen sulfide again and simultaneously obtaining methane without the hydrogen sulfide; and (2) performing deep dehydration to the methane without the hydrogen sulfide and obtained in the step (1), and adopting a polyimide or cellulose acetate organic polymeric membrane to separate methane and carbon dioxide in a finally-obtained gas mixture to obtain high-purity carbon dioxide and biogas methane. By means of the method, the biogas is prepared through the methane, the biological sulfur and the high-purity carbon dioxide are obtained, and the economic benefit of the methane is improved through the biogas, the biological sulfur and the high-purity carbon dioxide. |
