METHOD FOR EXTRACTING PHOSPHOROUS FROM SOLIDS USING ACTIVE LEACHING AND PHOSPHATE-ACCUMULATING MICROORGANISMS

摘要

The present invention relates to a method for selectively extracting phosphorous from heavy metal and phosphate-containing solids. In this method, the solid is treated with microorganisms under acidic, aerobic conditions, organisms comprising microorganisms that are active leaching organisms and those that store polyphosphates, so that the heavy metals and the phosphate are released from the solid and the released phosphate can be absorbed by the polyphosphate-storing microorganisms. The biomass that is enriched with phosphorous obtained in this manner is separated and can be used as biofertilizers, for example.
