Abstract
An organic waste decomposition treatment apparatus, wherein agitation vanes of flight members are rotatably attached to looped chains, so as to churn and ferment organic waste accumulated within a reservoir vat when the chain is rotationally driven, then be pushed towards an interior of the agitator by a push-down scraper which is positioned outside of the agitator at a back side of the agitator with respect to the direction of advancement, so as to eliminate contact resistance between the agitator and the organic waste at the back side of the agitator. It is thereby possible to make the agitator smaller and less expensive, and the decomposition treatment efficiency of organic waste is able to be increased.
