不同pH值下Fe3+对好氧活性污泥处理制浆中段废水的影响
Effect of Fe3 + on Pulping Middle-stage Effluent Treatment by Aerobic Activated Sludge under Different pH Values
摘要
Abstract
Effect of pH on treatment of pulping middle-stage effluent (PMSE) by aerobic activated sludge in the presence of Fe3 + was studied,with sludge without Fe3 + as blank control.COD removal efficiencies of experiment groups with and without Fe3 + achieved 77％ and 79％ respectively,when pH was 6.5,but the treatment effect decreased when pH value was out of this range.The present of Fe3 + enhanced the treatment effect,especially when pH deviated from the normal value,e.g.8.5 and 9.5.The dehydrogenase concentration and the flocculation ability of the sludge were also studied.The results showed that the two indicators in both groups were good when pH value in the range of 5.5 ～ 7.5,but deterioration occurred at other pH values.Compared to the blank control,both the activity and flocculation ability of the sludge with Fe3 + were better.关键词
