Improvement of Setting Characteristics of Activated Sludge by Addition of a Floc-Forming Bacterium

概要

論文の詳細を見る
A floc-forming bacterium, strain no.5,which made very large and easily precipitated flocs, was added as seed sludge in a bench-scale aeration tank. About one week allowed for production of activated sludge which could treat high-BOD wastewater at high-BOD loading while maintaining very good settling characteristics. The stran no. 5 was present at 3% of the activated sludge. Moreover, the settling characteristics of the activated sludge were much improved when the strain no. 5 culture was added to the bench-scale aeration tank or a large-scale deep aeration tank.
