摘要：Sludge bioflocculant was prepared from excess biological sludge by extraction method with dilute hydrochloric acid. A series of experiments were performed to investigate the flocculation efficiency of sludge bioflocculant towards starch and oily wastewater. The results indicated that the sludge bioflocculant had good efficiency towards starch and oily wastewater. More than 90% of flocculating rates were attained for the two kinds of wastewater. From the above study not only sludge could be recycled, a cheaper and readily available flocculant was attained from biological sludge, but also some kinds of wastewater could be treated with the sludge flocculant.
