| 摘 要： | 通过在锰砂及石英砂上固定自行分离的纤发茵属细菌,研究了生物固定化锰砂及石英砂滤柱的除铁除锰能力.从水厂成熟滤砂上分离出的纤发菌属细菌,经16S rDNA鉴定为却Lepto-thrix cholodnii(98%)、Leptothrix discophora(99%)、Leptothrix mobilis(99%).纤发菌属固定化锰砂及石英砂滤柱对铁的去除率均可达90%以上,但锰砂滤柱的处理能力高于石英砂滤柱.当DO为5 mg/L时,锰砂及石英砂滤柱对锰的平均去除量分别为0.9 ms/L和0.6 mg/L;当DO提高到9mg/L时,两滤柱对锰的平均去除量分别增加到1.45 ms/L和1.1 mg/L,相应的去除率分别从45%、34.5%提高到74.29%、59.32%.对生物膜形态的观察结果表明,纤发菌分泌的胞外聚合物与铁、锰氧化物形成了聚合体,同时还能观察到由嘉氏铁杆菌(Gallionella ferruginea)形成的麻花状沉淀物.

| Abstract: | Through immobilizing the isolated Leptothrix bacteria on manganese sand and quartz sand,the iron and manganese removal efficiency by the biologically immobilized filtration columns were studied.The isolated Leptothrix bacteria are determined by 16S rDNA to be Leptothrix cholodnii(98%),Leptothrix discophora(99%) and Leptothrix mobilis(99%).The manganese sand and quartz sand filtration columns immobilized by Leptothrix bacteria can remove ferrous iron of more than 90% but the manganese sand filtration column ... |
