NOVELTY - Method for processing organic fertilizer using animal excrements, involve mixing straw powder and regrind material produced by vegetable planting, uniformly mixing the agricultural waste straw mixture, animal excrements and zymophyte, fermenting the product, introducing the digested excrement water to sedimentation tank, inoculating and digesting sludge in the hydrolysis tank, obtaining suspended substance and introducing the product into constructed wetland plant treatment system after bacterial degradation.    USE - The method is useful for processing organic fertilizer which is used in constructed wetland (claimed).    ADVANTAGE - The method is environmentally-friendly.    DETAILED DESCRIPTION - Method for processing organic fertilizer using animal excrements, involve (a) mixing straw powder and regrind material produced by vegetable planting, and preparing agricultural waste straw mixture having water content of 55-65%, (b) regulating the water content of fresh animal excrements to less than 65%, (c) uniformly mixing the agricultural waste straw mixture, animal excrements and zymophyte, then sequentially carrying out primary fermentation to the product, dehydrating the product, turning the product periodically, performing secondary fermentation to the product, turning the product periodically and then terminating fermentation process, (d) removing impurities from the product, and shifting and crushing the product to obtain organic fertilizers, (e) introducing the remaining residues and waste liquid produced in the organic fertilizer in the steps (a-d) to septic tank for digesting the product, (f) introducing the digested excrement water to sedimentation tank, maintaining the product for 2-6 hours, settling and removing residues from the product, until the drainage water turbidity reaches less than 20 mg/l, (g) introducing the upper layer liquid in the sedimentation tank into hydrolysis tank for degradation treatment, inoculating and digesting sludge in the hydrolysis tank, connecting sewage distributing pipe from the lower middle portion of the hydrolysis tank, terminating the process after 4-8 hours, and obtaining suspended substance of less than 50 mg/l and (h) introducing the product into constructed wetland plant treatment system after bacterial degradation.
