| 摘 要： | 选用4种矿物材料对400g餐厨垃圾在35℃下进行4h好氧预处理,比较了预处理前后餐厨垃圾水解率的变化,并且详细研究了预处理对餐厨垃圾高温厌氧消化过程及产沼气效果的影响.结果表明:在同等条件下,添加矿物材料可以有效促进餐厨垃圾的水解,其中添加1.25%(质量分数,以餐厨垃圾湿基计)膨润土和添加2.5%轻烧MgO的处理水解率分别达到了96.79%和96.51%.轻烧MgO有效地缓解了餐厨垃圾由于酸化引起的pH值下降,使产气高峰期较早来到;而在总产气量上添加白云石粉的促进作用显著.膨润土次之,其中添加2.5%白云石粉的总产气量最高,为10925mL.添加矿物材料降低了消化液中钠离子的浓度,可减轻对产甲烷细菌的抑制作用.
