| 摘 要： | 在120r／min的搅拌及pH=1的强酸条件下，进行好氧颗粒污泥的强化解体实验，研究颗粒污泥的总数、平均粒径和粒径分布的变化情况。在15h实验时间内，搅拌强化解体的颗粒平均粒径从1230μm降至320μm，颗粒总数从30个／mL增至193个／mL。强酸强化解体结果类似，但解体时间为110h。搅拌比强酸对颗粒解体的强化作用更明显。粒径分布结果显示，小颗粒所占比例明显增加。颗粒解体过程中粒径分布均符合对数正态分布，但颗粒粒径的期望值石，随解体时间明显减小。根据颗粒的解体机理，即4种解体类型：破碎、破裂、剥落和研磨，结合实验结果，将解体过程分为对数期、平缓期、二次对数期和稳定期。
