The Research of Reduction Characteristics of Fe(III) Dissimilated by Different Activated Sludge

Abstract:

The effect of reduction characteristics of microbe dissimilating of Fe(III) under different activated sludge, carbon source and anoxic/anaerobic condition was studied by activated sludge as inoculum under laboratory condition. The results showed that the maximum accumulation of Fe(Ⅱ) and the reduction rate of Fe(III) inoculated by biological iron mud were higher than that inoculated by conventional activated sludge. The reduction characteristics of Fe(III) was better in nutrient solution as carbon source than that in sewage as carbon source when inoculated biological iron mud. But the reduction characteristics of Fe(III) was better in sewage as carbon source than that in nutrient solution as carbon source when inoculated conventional activated sludge. From the whole test, the reduction characteristics of dissimilating Fe(III) microbe under anaerobic condition were better than that under anoxic condition.
