| Research Abstract |
The biogenic iron oxides produced by iron oxidizing bacteria in the sediments of natural water bodies contains a large amount of iron-oxidized compounds that can adsorb phosphorus content. Therefore, this accumulation can play a significant role in the recycling of phosphorus resources. However, this sediment of phosphorus-rich accumulation cannot be efficiently utilized because it can be easily flushed by flowing water and because it is difficult to collect the accumulation from the sediments that usually contain anaerobic and malodorous mud. In this study, an effective method has been developed, in which a wood material carrier collecting the iron oxides can directly be used as phosphorus fertilizer and/or a phosphorus adsorption.
