- Abstract:研究了在微生物生长的不同时期投加混凝剂聚合氯化铝(Polyaluminium Chloride,PAC)对好氧颗粒污泥形成进程及污泥特性的影响。结果表明:反应器内微生物在1~7 d处于适应期,8~14 d处于对数增长期;在对数期、适应期投加PAC,成熟颗粒形成于第21d、26 d,分别比不加混凝剂的对照组提前了14 d及9 d;对数期投加PAC所形成颗粒的强度、密度、含水率(98.53%、1.059 1 g/cm3、92.76%)明显优于适应期投加PAC的(97.68%、1.038 0 g/cm3、94.36%)及对照组的(97.81%、1.045 5 g/cm3、95.04%)。研究表明,选择在对数期向反应器内投加PAC强化造粒可以显著加快颗粒化进程,并提高污泥颗粒的稳定性和沉降性。
