Worm type biomimetric fermenter

A fermentor used in aerobic fermentation treatment to a siftage which mainly has organic matters based on the household garbage is provided. The utility model is provided with a fermentation chamber which is composed of a trapeziform side wall, an cambered back inner wall, a slick slope shaped abdomen inner wall, as well as an feeding inlet and a discharging outlet, the whole is in the state of incline, and the feeding inlet is higher than the discharging outlet. Materiel is evenly delivered into the fermentation chamber by a feeding device, due to the action of gravity, materiel moves towards the discharging outlet end slowly along the abdomen inner wall in the process of ferment, water and oxygen needed in the process of ferment are respectively supplied by a spray pipe arranged at the back of fermentor and a vent at the abdomen, exhaust gas and infiltration liquid produced in the process of ferment are respectively discharged through an air exit hole at the back and a liquid exit hole at the abdomen, and the infiltration liquid can be recycled through the spray pipe by a spray returning device.
