Abstract

Biogas from chicken manure with anaerobic digestion has a high concentration of H₂S, which needs to be removed before further utilization such as power generation or purification to produce bio-natural gas. A batch experiment of chicken manure digestion was carried out in this study, and trace amount of air was introduced into the reactors to remove hydrogen sulfide by biological oxidation. The test was carried out by feeding the inoculum obtained from the effluent of chicken manure methane digestion reactor under mesophilic conditions, and introducing air at level of 7~50mL/g VS. Air introduction significantly reduces the H₂S concentration in the biogas. The experimental group with an air dosage of 30mL/g VS had the highest average desulfurization efficiency of 62%. At the same time, the cumulative methane production of the experimental group with an air dosage of 30mL/gVS reached 335mL/gVS, which was 78.6% higher than the control group. The biological desulfurization method with trace amount of oxygen has the application prospect of simple procedure and efficient removal of H₂S.
