【摘要】 目的检测混合细菌对铁锰氧化过程各因素的变化,深入了解微生物除铁除锰的过程及其特性,为微生物在实际工程中的应用提供依据.方法采用亚铁杆菌属分离培养基、嘉氏铁柄杆菌分离培养基、缠绕纤发杆菌分离培养基和PYCM分离培养基对细菌进行驯化培养,后分别混合,通过在不同条件下的对比试验,检测细菌氧化铁锰时各因素的变化.结果细菌在氧化铁锰时所引起的溶液pH值的变化与细菌在氧化锰过程中,锰去除率的变化曲线有着一定的线性关系;每种混合菌对锰的去除率都能达到50%以上,对铁的平均去除率在80%以上.结论有无载体对细菌除铁影响并不是很大.在有砂摇动和无砂摇动情况下由嘉氏铁柄杆菌分离培养基、缠绕纤发杆菌分离培养基和PYCM培养基培养出的细菌混合后对铁锰的去除效果好,在有砂不摇动情况下由亚铁杆菌属分离培养基、嘉氏铁柄杆菌分离培养基、缠绕纤发杆菌分离培养基和PYCM培养基培养出的细菌混合后对铁锰去除效果好.细菌对铁锰的氧化作用影响着溶液的pH值.更多还原

【Abstract】 In order to test the factors change in the oxidation process of the mixed bacteria removing iron and manganese and to know the course and characteristics of the microorganism removal of iron and manganese,we use Ferrobacillus,Grenathrix polyspora,Leotothrix volubilis and PYCM medium to culture the bacteria,and mix them.We did comparative test in different condition and detect the factors change.There is the linear correlation between the change of pH and the removal rate curve of the manganese.The manganese removal rate of each bacteria can reach over 50%,the average removal of iron is over 80%.Carrier does limited effect on the biological removal of iron.The removal effect of iron and manganese,which depends on the Grenathrix polyspora,Leotothrix volubilis and PYCM culture medium,is better under the condition of having sands and waving the bottle and only waving the bottle.When only sands exist,the biological removal of iron and manganese is better which depends on the Ferrobacillus,Grenathrix polyspora,Leotothrix volubilis and PYCM culture medium.The oxidation of the iron and manganese by bacteria has effect on pH.更多还原
