<p><P>PROBLEM TO BE SOLVED: To enable urine mixed with discharged feces in a turbid state, high concentration organic waste liquid having a slurry BOD of about 15,000-35,000 mg/l to be used as liquid manure in a pasture, a field, and the like, and applied to further advanced treatment, by pouring the organic waste liquid into a filter bed type treatment tank filled with a microorganism carrier, such as a wood chip and completely fermenting the organic waste liquid with thermophilic aerobic microorganisms. <P>SOLUTION: In the treatment method of the high concentration organic waste liquid and its treatment device, the slurry high concentration organic waste liquid, such as excrement, having a BOD of 15,000-35,000 mg/l is poured for a short while into the filter bed type treatment tank of which the outer periphery is surrounded with an insulated muffler and which has a BOD load of 5-10kg/m<SP>3</SP>day, then fermented with the thermophilic aerobic microorganisms carried by the microorganism carrier while being always ventilated with air from below a filter bed, and permeate which has permeated so as to wash away between the microorganism carriers and stored under the filter bed is circulated onto the filter bed of the filter bed type treatment tank, thereby treated liquid applied to the liquid manure having a BOD of 1,000-2,000 mg/l or to the further advanced treatment is obtained after about 1-2 days. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
