NOVELTY - Processing sewage sludge, comprises: e.g. (i) providing a sewage to a storage tank and precipitating; (ii) separating a clear liquid by mechanical action after precipitation; (iii) filtering the separated liquid using a filtering device and providing the liquid part into a liquid storage pool for further use; (iv) quickly and uniformly stirring the filtered liquid; and (v) standing the stirred slurry to precipitate, uniformly drying the stirred slurry and grading, centrifuging the grinded slurry to obtain a slurry with different meshes and storing the obtained slurry.    USE - The method is useful for processing sewage sludge for the preparation organic fertilizer.    ADVANTAGE - The method is capable of processing sewage sludge without any environmental pollution in a simple manner.    DETAILED DESCRIPTION - Processing sewage sludge, comprises: (i) providing a sewage to a storage tank and precipitating for 10-24 hours; (ii) separating a clear liquid by mechanical action after precipitation of 10-24 hours; (iii) filtering the separated liquid using a filtering device and providing the liquid part into a liquid storage pool for further use; (iv) quickly and uniformly stirring the filtered liquid at 8-22 degrees C through a speed-adjustable stirring device; (v) standing the stirred slurry to precipitate after 10-30 minutes, uniformly drying the stirred slurry and grading to 325, 200, 120, 80 meshes respectively, centrifuging the grinded slurry to obtain a slurry with different meshes and storing the obtained slurry for 8-24 hours; (vi) depositing the obtained slurry with different meshes into a supernatant liquid collecting reservoir and the filtering device, to obtain a reaction mixture and filtering the obtained mixture; (vii) delivering the obtained mixture with sulfuric acid in a concentration of 10-32%, centrifugal pumping the mixture and adjusting a pH value of the mixture to 6.5-7.5; (viii) uniformly stirring the mixture in a storage tank, depositing the mixture for 10-30 minutes and standing for 2-6 hours; (ix) depositing the mixture into liquid storage tank, providing liquid part into the same type property of liquid storage tank after precipitating the mixture, and adjusting a pH value of the reaction mixture to 6.5-7.5 and fertilizing the reaction mixture containing a silicon fertilizer or powder into a dispersant; (x) providing the dispersant into the blending device after pressure filtering the material and uniformly stirring to paste and packaging the paste to obtain quick-acting fertilizer containing silicon dioxide, where 40-45% of the silicon fertilizer comprises aluminum, iron, calcium, phosphorus, sodium, magnesium, titanium, potassium, zinc, barium, manganese element and 5-10% of micro-element; (xi) adding the fertilizer with a dispersing agent after pressure filtering the material, stirring uniformly and drying into the homogeneous and packaging the homogeneous mixture in the form of powder, which contains 85-95% of silicon dioxide, and a metal ion content of 1000-8000%; (xii) depositing the homogeneous mixture and heating to a temperature of 28-38 degrees C, adding hydrochloric acid liquid with a concentration of 20-31% in a centrifugal pump and controlling a pH value of the mixture to 6.5-7.5; (xiii) stirring the reaction mixture in the storage tank, depositing the mixture for 10-30 minutes, and standing for 4-8 hours, pumping the slurry part clear liquid into the liquid storage tank and providing the precipitate into filtering device to obtain a material for further use; (xiv) filtering the prepared material after enter into animal breeding odor-removing product producing process, and stirring at the same time, adding menthol or mint essence and stirring them uniformly, drying the mixture, which is cleared animal excrement peculiar smell, and recycling the animal excrement, the silicon fertilizer and animal organic fertilizer to produce clean biological organic fertilizer; and (xv) filtering the organic fertilizer, adding dilute sulfuric acid with a concentration of 0.1-1%, stirring and washing reaction material, controlling a pH value of the mixture to 3-5, standing and depositing the mixture for 8-16 hours, taking the supernatant and providing into the storage device with corrosion resistant function for further use, adding neutral water with the reaction mixture to stir, washing and precipitating the stirred mixture, filtering the material, stirring uniformly, and drying and packaging to obtain the animal-breeding odor-removing product comprising 85-95% of silicon dioxide, iron and manganese.
