膨胀污泥和泡沫中的丝状菌及其控制

Filamentous Microorganisms and Control in Activated Bulking Sludge and Foaming

本文对活性污泥废水处理中的丝状微生物的形态进行了观察。结果表明,在城市废水处理厂的活性污泥中,引起污泥膨胀的丝状菌主要有Microthrix Parvicella,Nostocoida Limicola,0041,Thiothrix I,0092和Nocardia SP等;泡沫中的丝状菌为M.Parvicella和NocardiaSP.进一步分析了引起污泥膨胀的丝状菌繁殖条件及控制方法。

Microscope observation on filamentous microorganisms presenting in activated sludgewastewater treatment processes was accomplished. The results indicated that the fila-ments causing sludge bulking could be observed frequently were Microthrix parvicella,Nostocoida limicola, 0041, Thiothrix I, 0092 and Nocardia sp etc. and the filaments caus-ing scum were M. Parvicella and Nocardia SP. The proliferous Conditions and controlmethods on filamentous microordanisms causing sludge bulking and foaming were alsostudied.
