| Abstract: | The three methods of immobilized Mn 2+ removal bacteria from groundwater were analyzed in this paper.It was showed that bacteria in the water immobilized on the sand themselves by elutig the sand column with groundwater.After matura immobilization for 50 days the sand column could remove Mn 2+ effectively and stably.A strain of bacteria,which is isolated from the mature sand,is crosslinked by getutaraldehyde for 2?7 days.The sand with the immobilized a strain of bacteria could remove Mn 2+ from water over two weeks.It was found that the sand column is leaked manganese in the immobilization of the mixed bacteria enriched from the mature sand in different mediums.Dissolved O 2 and CO 2 in the water,pH,Fe 2+ ,Mn 2+ ,filtrating velocity and period,the strength of back wash are critical to the immobilization,and thus,the Mn 2+ removal of the filters. |
