中文摘要：

城市污水厂产生的污泥中含有多种产氢菌和大量的蛋白质、碳水化合物等有机质,是潜在的发酵产氢基质之一.研究了碱处理和热处理对污泥发酵产氢途径的影响.结果表明,热处理比碱处理有更强的灭菌作用,可以有效杀死耗氢菌.热处理筛选到的产氢菌主要为嗜酸的产氢菌,而碱处理筛选到的产氢菌主要为嗜碱的产氢菌.碱处理污泥的最大产氢量在初始pH11的实验组获得,为10.32mL/g-COD;而热处理污泥的最大产氢量在初始pH5的实验组获得,为8.94mL/g-COD.热处理污泥在酸性条件下（pH＆lt;6）的产氢主要是由利用葡萄糖的菌通过发酵碳水化合物产氢,而碱处理污泥在碱性条件下（pH＆gt;9）的产氢主要是由利用蛋白质的菌通过发酵蛋白质产氢.
