Hydrogen sulfide (H₂S) is a toxic and hazardous gas and is commonly present in livestock operations, which occasionally causes associated exposure accidents. This study evaluated the effectiveness of electrochemical control of H₂S in lab-scale swine manure storage using different electrode materials, and further selected suitable materials to demonstrate the performance of a pilot-scale field test in the deep-pit manure storage of a 200-head swine barn. In the lab-scale test, electrochemical sulfide oxidation mainly contributed to the H₂S mitigation, resulting in high H₂S removal efficiencies when using low carbon steel (LCS) and stainless steel 304 (SS304) as electrodes. Based on their better H₂S treatment performance and lower material costs, LCS and SS304 were selected for the pilot-scale test. In a 92-day operation, the pilot-scale demonstration showed H₂S removal efficiencies of 84.0% and 63.5% for LCS and SS304, respectively. A techno-economic assessment indicated that the installation and operation of the electrochemical system accounted for 16% of barn construction cost using LCS as electrodes. Further optimization may substantially decrease the electrode material consumption and the overall cost.

硫化氢（H ₂ S）是一种有毒有害气体，通常存在于畜牧业中，偶尔会引起相关的暴露事故。这项研究评估了使用不同的电极材料对实验室规模的猪粪中H ₂ S进行电化学控制的有效性，并进一步选择了合适的材料来证明200磅深坑粪便中试规模现场测试的性能。头猪舍。在实验室规模的测试中，使用低碳钢（LCS）和不锈钢304（SS304）作为电极时，电化学硫化物的氧化主要有助于缓解H ₂ S，从而提高了H ₂ S的去除效率。基于他们更好的H ₂S处理性能和较低的材料成本，选择LCS和SS304进行中试规模测试。在为期92天的操作中，中试规模的演示表明，LCS和SS304的H ₂ S去除效率分别为84.0％和63.5％。技术经济评估表明，使用LCS作为电极，电化学系统的安装和运行费用占谷仓建设成本的16％。进一步的优化可以大大减少电极材料的消耗和总体成本。
