| 摘 要： | 目的]筛选微生物絮凝剂高效产生菌,并优化其培养条件。方法]从活性污泥中分离纯化絮凝剂产生菌株,考察它们对焦化废水的絮凝效果,并探讨了利用糖蜜废液作为廉价培养基扩大培养菌株的可行性。结果]从活性污泥中共得到4株絮凝率〉70%且絮凝特性稳定的菌株。其中,J-Y1和J-Y2菌液的絮凝活性最好,对高岭土悬浊液的絮凝率分别为94.4%和98.9%,在处理焦化废水时絮凝率最高分别也达到88.4%和93.9%。J-Y1和J-Y2在糖蜜废液中均生长良好,且糖蜜浓度未对絮凝率产生显著抑制。结论]糖蜜废液可为J-Y1和J-Y2的扩大培养提供廉价的营养,并且这两个菌株在优化的试验条件下均具有相当高的絮凝能力,表明它们在废水处理中有巨大的应用潜力。
