Abstract:
     A method of agricultural fertilizer city excrement industrialized production is that the collect excrement is fermented first, and is dewatered by horizontal spiral centrifugal, the frafmenting, prilling, drying and slerilization treatment is carried on by the hot wind style groove type of stirring drying prilling machine into graininess fertilizers, again the phosphorus ores powder and rare-earth elements, etc. are added, finally the concentrated compound fertilizers are packed. The dewatering separated dilute liquid may be used as by-product of liquid fertilizer. The fermentation productive methane may be used as fuel of hot wind furnace. The waste heat of tail-gas of hot wind furnace productive hot wind through drying and prilling machine may also be used for heating fermentation.
