Title:
METHOD AND APPARATUS FOR ORGANIC WASTE PRETREATMENT
Document Type and Number:
WIPO Patent Application WO/2013/073789
Kind Code:
A1
Abstract:
The present invention relates to a method and apparatus for organic waste pretreatment. The method for organic waste pretreatment includes: a step (a) of allowing organic waste to penetrate an orifice or venturi tube having a sectional area less than that of an inflow hole at a pressure of 25 psi to 1,999 psi; and a step (b) of injecting ozone into the organic waste before or after step (a) or at the same time. The organic waste pretreatment apparatus includes: a chemical tank supplying chemicals into organic waste; a cavitation treatment bath supplying the organic waste at a pressure of 25 psi to 1,999 psi by using a pump; a cavitation unit resupplying the organic waste into the cavitation treatment bath after the organic waste supplied from the cavitation treatment bath passes through an orifice or venturi tube disposed therein; and an ozone reaction bath ozonizing the organic waste by using ozone. Thus, organic waste may be effectively pretreated by the organic waste pretreatment apparatus.
