PURPOSE: Provided is a method for preparing high quality liquid fertilizer from organic wastes containing much water without bad smell in a short time by using polyphenolic humic substances. CONSTITUTION: The preparation method of high concentration liquid fertilizer comprises the steps of: removing impurities and salts from organic wastes; supplying humus microbes producing polyphenolic compounds for aerobic fermentation; dehydrating to get waste cakes and liquid, dehydrated liquid, which are sent to a composting room and a liquid storage tank, respectively; aging the liquid to be humification grade more than 90% in an aerobic agitation tank; precipitating sludge and microbes, which sent to a microbe-culturing room; activating supplied sludge and microbes in a bio-reactor filled with colloidal micelle pellet including humic acid of sea, activated minerals like pumice and ferrite for obtaining a culture liquid containing polyphenolic humic substances; sending the culture liquid to the aerobic agitation tank for high quality liquid fertilizer. |
