Abstract
Activated sludge obtained from the night soil treatment plant was immobilized using acrylamide and nitrification and the BOD removal of the sewage were studied by using the immobilized activated sludge which was packed in a single treatment tank. The findings indicated that the ratio of nitrification in the immobilized gel tank was larger than that in the free activated sludge tank in every operation period, and the rate of BOD removal in the immobilized gel tank was roughly equal to that in the free activated sludge tank in this condition. The findings indicated that the application of immobilized activated sludge to the sewage treatment enabled the sewage treatment process to be more efficiency and compact.
