摘要
从实验室好氧池活性污泥中分离出高效絮凝剂产生菌株AspergillusM-25,经初步鉴定为曲霉属。通过设计正交实验找出其最大影响因素及最佳条件。实验结果表明,该菌株在查氏培养基培养,初始pH值为5 0,转速为140r min和水浴温度为25℃的条件下能产生高效絮凝剂,对高岭土悬浊液的絮凝率达到97 15%。
A strain of microorganism named Aspergillus M-25 which produces flocculant was isolated from activated sludge.Through orthogonal test,the optimum cultural conditions were found to be Zapeke,primary pH 5.0,25 ℃ and 140 r/min.The strain produced a strong\|activating flocculant with flocculating rate of 9715% against kaolin clay suspension.
