壳聚糖絮凝破壁后大肠杆菌菌悬液的研究
FLOCCULATION OF E.coli DISINTEGRATES WITH CHITOSAN
【摘要】 在不同离子强度等条件下用壳聚糖作为主要的絮凝剂对用ＫＯＨ破壁后的大肠杆菌悬液进行了絮凝研究，考察了不同絮凝条件对悬液过滤速度，絮凝物的量，ｐＨ值，浑浊程度ＯＤ６００及ＣＯＤ去除率等的影响。得出了酸的加量与壳聚糖加量的线性关系。
【Abstract】 In this paper. cationic polyelectrolyte chitosan,together with sodium chloride and chlorhydric acid was used to flocculate recombinant E.coli disintegrates after the intracellular product PHAs was removed. Effects of ionic strength, chlorhydric acid and chitosan dosage on flocculation results, pH, OD600, filtraton speed, COD removal were studied, flocculation mechanism was also discussed.
