摘要：Convening dewatered heterogeneous sludge containing organic wastematerials into a homogenous extract of carbon and amino acids for fertilizer productionby adding sulfuric acid to the sludge; pumping the mixture through a blending mixer tomix the sludge with the sulfuric acid; adding conditioning chemicals to the mixture:pumping the mixture through a shearing mixer to mix the conditioning chemicals into themixture; and mechanically agitating the mixture to create the homogenous extract.Optionally, the extract is pumped into a pipe reactor for reaction with an acid and a baseto form a melt, which is rolled onto fertilizer particles to form accreted granules. Theaccreted granules are dried to form a granular fertilizer. Also described is an organically-enhanced granular nitrogen-phosphorous-sulfur fertilizer having at least about 0.5% byweight total carbon and amino acids, and accreted granule size greater than or equal toabout 1.7 mm. The fertilizer is noncombustible.
