Abstract

Methane (CH₄) and hydrogen sulfide (H₂S) production from sewers are significantly driven by microbial activities in anaerobic sediments. This study proposes a novel ferrous activated sodium percarbonate advanced oxidation process to inhibit CH₄ and H₂S production. By targeting microbial activity in the top layer (0–2 cm), the process achieved 74.8 ± 4.3 % and 60.5 ± 2.5 % reductions in CH₄ and H₂S production, respectively. The generated free radicals ([rad]O₂⁻, [rad]OH, and [rad]CO₃²⁻) compromised cellular integrity and disrupted intracellular enzyme systems. Enhanced hydrolytic enzyme activities and inhibition of enzymes involved in CH₄ and H₂S production pathways facilitated organic matter retention and transformation. Microbial community analysis confirmed a decrease in sulfate-reducing bacteria and methanogenic archaea, while hydrolytic acidogenic bacteria increased. This study demonstrates a sustainable and effective oxidation-based strategy for integrated sewer gas control and improved wastewater treatment systems performance.
