In this study, the feasibility of bioflocculant prepared from excess sludge to reduce its production costs and carve out a new way to attain bioflocculant was investigated. Three reagents were used to disintegrate excess sludge including alkali, acid and oxyful. Results showed that the performance of alkali treatment was the best. The flocculating rate of the prepared bioflocculant by the alkali a...Show More
