  • 摘要: 在污泥厌氧发酵产酸过程中,以富集同型产乙酸菌的污泥为研究对象,通过pH值、种泥浓度和底物浓度的变化,对发酵过程中有机酸分布和乙酸累计情况进行实验研究。实验结果表明,碱性条件有利于产乙酸菌的生长,但影响产氢产乙酸菌,尤其是丁酸降解菌的作用。产氢产乙酸菌和同型产乙酸菌的互营作用在发酵6 d后广泛存在;底物浓度过大,产氢产乙酸与同型产乙酸的互营机制受到抑制。
    Abstract: The experiments were conducted to study the effects of substrate concentrations, sludge concentration and pH value conditions in the enrichment of homoacetogens during sludge anaerobic digestion process. The distribution of organic acid and the accumulation of acetic acid in the anaerobic fermentation process were studied.The results showed that the alkaline conditions were conducive to the production of acetic acid, but hydrogen production bacteria, especially butyric acid degrading bacteria was inhibited. Production of hydrogen production bacteria and homoacetogens was widely present at just 6 days, and propionic and butyric acid degrading bacteria reaction was not actually the same under different pH conditions. The concentration of substrate was so high that the trophic link between syntrophic acetogens and homoacetogens was suppressed.
