  • 摘要: 为了揭示腐殖酸对H2S产量的抑制机制，设计了生活垃圾中添加腐殖酸的厌氧消化实验，并为排除其他因素干扰，将与生活垃圾拥有相同硫含量的硫酸钠与牛血清蛋白分别与腐殖酸进行厌氧消化实验，同时测定了消化前后腐殖酸得失电子能力，判断腐殖酸是否会抑制厌氧消化过程中H2S的产生。结果表明：在厌氧消化实验中，腐殖酸的添加导致H2S产量明显降低；在牛血清白蛋白组实验中，H2S的去除率达到83.56%，硫酸钠组实验中H2S去除率只有24.20%；而测定腐殖酸得失电子实验中，厌氧消化后的腐殖酸得电子能力明显低于厌氧消化前，表明腐殖酸在厌氧消化过程中参与了电子的争夺，H2S的生成亦须得到电子，故腐殖酸在H2S的生成阶段通过抢夺电子而在源头上抑制了H2S生成。
    Abstract: Abstract The tests of anaerobic co-digestion of RSW and humic acid were designed and conducted to investigate the inhibition mechanisms of humic acid on H2S production during anaerobic digesiton. The sulfur content of RSW was replaced by bovine serum albumin(BSA) and sodium sulfate, respectively, to eliminate the disruption of other compositions, and the tests consisted of anaerobic co-digestion of humic acid and BSA, and humic acid and sodium sulfate. The electron resistance of humic, humic acid electron acceptor model-AQDS and BSA were measured by an electrochemical cell. The results indicated that the production of H2S decreased remarkably by the addition of humic acid. The removal rate of H2S in the BSA group was 83.56%, while the sodium sulfate group was only 24.20%. Electron acceptors of humic acid after anaerobic digestion was significantly lower than those before anaerobic digestion, demonstrating that humic acid played the role of electron transfer during anaerobic digestion. Since the electrons are also needed in the formation of H2S, therefore, humic acid inhibits H2S at the source of its formation by snatching electrons.
