Ozone from a pilot-scale ozone generator was treated on fermented pig liquid manure stored in a storage tank in order to reduce odor substances during the process of fermented liquid manure production. The group of ozone treatment showed one less than the organic matter compared that of the control. The preferable condition for characteristic changes was when the ratio of BOD to COD was less than 1.5. Ozone treatment showed better oxidizing power than control as it removed more suspended solids and had less methyl isobutyl ketone(P less than 0.05).
