The manufacturing method of an artificial culture soil and artificial culture soil fertilizer using water sludge

摘要

The present invention relates to a method of manufacturing artificial soil using constant sludge and a method of manufacturing artificial soil fertilizer, and more particularly, to recycle artificial sludge to produce porous low specific gravity artificial soil, and at the same time, to produce artificial earth, By absorbing the fertilizer components, we can prepare artificial alkaline fertilizers that can contain fertilizer components that have been absorbed for a long time under soil-like conditions, thereby reducing the overall cost of treating sludge and growing crops, and drying the soil. And prevents acidification and at the same time prevents secondary pollution of water quality.;Artificial soil production method using the constant sludge according to the present invention, constant sludge 55 ~ 65%, diatomaceous earth 5 ~ 15%, volcanic stone 5 ~ 10%, red earth 10 ~ 20%, blowing agent 5 ~ 10% After the material mixing step 11 for mixing the sludge and each subsidiary material using the equipment capable of mixing and conveying, and the material mixing step 11 described above, the blended material is passed through a mill to a size of 1.5 to 2 mm in diameter. After the pulverization step 12 and the pulverization step 12 above, the pulverized blended material is put into a mesh drying chamber, and the drying time is 80 to 100 minutes and the drying temperature is 280 to 320 ° C. After the moisture control step 13 for controlling the moisture of the compounding material corresponding to the level of 30 to 40%, and the water control step 13, the compounding material containing 30 to 40% water Primary molding step 14 for forming a predetermined shape by passing the through a drill extruder, and the primary After the molding step 14, the secondary molding step 15 of converting the compounding material formed into a predetermined shape into a drum-shaped rotary molding machine into a spherical shape and the secondary molding step 15 described above After coarse, the above-mentioned spherical compounded material was put into a low temperature drying furnace which is a drum-type rotating body, and the drying time was 50 to 70 minutes and the drying temperature was 55 to 65 ° C. After the drying step (16) for drying the moisture to a level of 7 to 8% and the drying step (16) described above, the compounding material formed into a spherical shape is put into a high-temperature baking furnace, which is a drum-shaped rotary body, and fired. After firing at 110 to 130 minutes and firing temperature at 900 to 1000 ° C., a high temperature firing step (17) for producing artificial soil and a high temperature firing step (17) described above are carried out. The cooling process (18) for cooling the artificial soil by spraying the coolant at room temperature to the soil According to the present invention, a method of manufacturing artificial soil fertilizer using constant sludge according to the present invention passes through the above-described high temperature baking process (17), and cooling water containing liquid-free, organic fertilizer in the artificial soil discharged from the high temperature baking furnace. It is characterized by passing through the fertilizer component moisture absorption process 21 to absorb the fertilizer component on the artificial soil by spraying.
