NOVELTY - Producing soil conditioner using waste of food leachate, comprises (S10) screening solid foreign matter from waste of food leachate, (S20) removing organic matter of waste of food leachate, and culturing Bacillus subtilis to proceed anaerobic fermentation and aerobic fermentation, mixing anaerobic fermentation liquid and aerobic fermentation liquid and maintaining temperature, pH and Bacillus subtilis concentration to produce soil conditioner, (S40) precipitating soil conditioner for separating soil conditioner, and (S50) re-processing the soil conditioner.    USE - The method is useful for producing soil conditioner (claimed).    ADVANTAGE - The method produces soil conditioner at low cost and prevents environmental pollution caused by waste water.    DETAILED DESCRIPTION - Producing soil conditioner using waste of food leachate, comprises (S10) screening solid foreign matter contained in the waste of food leachate, (S20) removing organic matter of the obtained waste of food leachate, and culturing Bacillus subtilis to proceed independently anaerobic fermentation (S21) and aerobic fermentation (S22) side by side, (S30) mixing the 50-75 vol.% anaerobic fermentation liquid and 25-50 vol.% aerobic fermentation liquid, and maintaining temperature of 50-60 degrees C, pH of 5-6 and Bacillus subtilis concentration of more than 106 cfu/ml to produce soil conditioner, (S40) precipitating soil conditioner from the fermented mixture for separating the soil conditioner, and (S50) re-processing the obtained soil conditioner via the aerobic fermentation. The fermentation step comprises (i) maintaining aerobic microorganism concentration of 27000-33000 mg/l in the food waste effluent, and temperature of 45-70 degrees C for 10-12 days to perform aerobic fermentation, (ii) culturing microorganism by maintaining anaerobic microorganisms concentration of 2500-7500 mg/l and temperature of 48-55 degrees C for 2-4 days to perform anaerobic fermentation of the food waste effluent, and (iii) mixing the 50-75 vol.% anaerobic fermentation liquid, 25-50 vol.% aerobic fermentation liquid with Bacillus subtilis concentration of more than 106 cfu/ml to produce soil conditioner. An INDEPENDENT CLAIM is also included for soil conditioner produced by the above method.
