Densification of Autotrophic Bacteria Sludge and Its Characteristics for Wastewater Treatment
|
Abstract:
Autotrophic granular sludge was developed in an SBR reactor using inorganic carbonal substrate.The variation of ammonia-oxidizing bacteria(AOB) and nitriteoxidizing bacteria(NOB) during the densification process and their effects on granulation have been evaluated.It was found that the autotrophic bacteria granular sludge was compact with the density reached up to 1.06 g/mL,and the rod-like bacteria predominated in granules on the evidence of scanning electron microscopic(SEM) results.Ammonia,nitrite and ni...
