Ca²⁺、Mg²⁺对好氧污泥颗粒化的影响研究

Gongye shui chuli, 2015
研究了投加不同金属离子(Ca2+、Mg2+)在好氧污泥颗粒化过程中的作用,简要分析了颗粒形成过程中污泥的形态和物化性质变化,重点探究Zeta电位、胞外多聚物(EPS)的变化以及两者之间的关系。在接种普通活性污泥的2个序批式反应器中分别投加等量40 mg/L的Ca2+和Mg2+,培养运行34 d,2个反应器都已全部颗粒化,结果显示添加Mg2+更有利于缩短好氧颗粒污泥系统的启动时间,而添加Ca2+形成的颗粒污泥平均粒径较小,添加Mg2+更能促进EPS的分泌。底物匮乏期,添加Mg2+较添加Ca2 ...
