摘    要:用GCI培养基从曲阳污水厂污泥和俞泾浦底泥中分离出3株产生高絮凝活性的微生物,所研制出的微生物絮凝剂对高岭土悬浊液、土壤悬浊液和碱性染料废水均有良好的净化效果.在对微生物絮凝剂的助凝作用上,CaO的效果明显优于CaCl2.微生物絮凝剂(液体)适宜的投加量为1.0% ,相应的助凝剂CaO(1.0% 浓度)适宜投加量为2.0%.在研制微生物絮凝剂的过程中,适宜的摇瓶培养时间为72h,絮凝剂分离时适宜的离心条件为中高速(5000~10000r/m in).离心速度太高、时间太长不仅造成离心设备投资和能耗的增加,而且会减少离心上清液中絮凝物质的含量,从而导致絮凝效果的降低

关 键 词:微生物  絮凝剂  废水处理

Abstract:Microbes which can produce bio coagulants were isolated from activated sludge of the Quyang Wastewater Works and also from the settlings of the Yujing Creek.Several kinds of polluted waters such as kaolin suspension can be purified efficiently by the use of the bio coagulants produced in this research.Coagulation can be apparently improved when using calcium oxide as the coagulating aid. The excellent bio coagulants can be produced when a 72 hour's continued cultivation was performed.In the process of bio coagulant's isolation,a proper centrifugal conditions was suggested because too strong centrifugation may result obvious decrease in the coagulating efficiencies.
Keywords:microbe  coagulant  wastewater treatment
