固体からリンを選択的に回収する方法
Document Type and Number:
Japanese Patent JP5746029
Kind Code:
B2
Abstract:
The present invention relates to a method of selectively obtaining phosphorus from solids containing heavy metals and phosphate. In this method, the solid is treated under acidic aerobic conditions using microorganisms comprising leaching microorganisms and polyphosphate-accumulating microorganisms, so that the heavy metals and the phosphates are released from the solid and the released phosphates may be taken up by the polyphosphate-accumulating microorganisms. The phosphorus-enriched biomass that is obtained in this manner is separated and may be utilized, e.g., as organic fertilizer.
