摘要
Convening dewatered heterogeneous sludge containing organic waste materials into a homogenous extract of carbon and amino acids for fertilizer production by adding sulfuric acid to the sludge; pumping the mixture through a blending mixer to mix 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 the mixture; 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 base to form a melt, which is rolled onto fertilizer particles to form accreted granules. The accreted 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% by weight total carbon and amino acids, and accreted granule size greater than or equal to about 1.7 mm. The fertilizer is noncombustible.
