PURPOSE: Provided is a method for treating livestock wastewater, which can treat a large amount of livestock wastewater in short time at low cost, and recycle as liquid fertilizer and antiseptic solution. CONSTITUTION: The method comprises the steps of (a) collecting livestock wastewater, (b) separating the livestock wastewater into solid and liquid by centrifugal dehydration, (c) decomposing organic material in the liquid by oxidation and collision of high velocity gas, (d) mixing the liquid treated at the step (c) to regulate its components and promoting oxidation and aerobic microorganism digestion by bringing the treated liquid into contact with air, (e) feeding coagulant to the treated liquid of the step (d) to remove no settled colloidal substances and color, (f) separating sludge generated from the step (e), (g) separating fine deleterious particles by sedimentation, (h) using the decant water of the step (g) as liquid fertilizer, and (i) using the decant water as antiseptic solution after exposing the decant water to heavy oxygen (O3).
