摘要/Abstract

摘要： 长链脂肪酸on-Chain Falty Acids简称ICFAs)是动植物油脂的主要组成之一，常见干屠宰场房水、含棕榈油的废水处理当中。厌氧消化处理这类废水往往由于高浓度长链脂肪酸的存在造成反应器的酸化。因此，厌氧消化降解长链脂肪酸一直是废水处理当中的一个难题。近2a关于微生物种间电子传递的研究为长链脂肪酸的降解提供了一个新的思路。本文阐述了厌氧消化降解长链脂肪酸的2种电子传递机理，间接电子传递与直接电子传递:讨论了其机理和强化直接电子传递的方式。包括添加颗粒活性炭，导电碳布以及生物炭等方式来增强直接电子传递，有效提高长链脂肪酸的降解速率，发挥其产甲烷潜力。
