摘 要：
The nitro compound fertilizer slurry is prepared from extraction residual acid,ammonium phosphatesludge acid and concentrated sludge acid. The effects of different process conditions on the viscosity of nitrocompound fertilizer slurry are investigated. The optimum process conditions production nitro compound fertilizerslurry are proposed, including mass ratio of nitric acid and slag acid(m(extraction residual acid sludgeacid) : m(phosphate ammonium sludge acid) : m(concentrated sludge acid) of 1.07:1.19:1.00) in 0.9~1.1,slurry p H of 5.6~6.0,w(H_2O) of slurry in 25% ~30%.
