Title:
COMPOST FERMENTATIVE TREATMENT
Document Type and Number:
Japanese Patent JPH11157973
Kind Code:
A
Abstract:

To provide a method for the subject treatment of organic objects such as livestock droppings, intended for complete killing Escherichia coil and the like in a short time after beginning the treatment operation, preventing the above bacteria from proliferation again until ending the treatment and ensuring fermentation temperature to be controlled by a simple means.

This method for compost fermentation treatment has such a scheme that, when a compost fermentation is to be conducted by charging organic objects holding Escherichia coil into an open-type formentation tank equipped with a blower for feeding air into the tank, the air feed time and air feed that halting time for the blower are controlled and such operations are repeated so that the fermentatin temperature of the objects is kept at ≥60°C until the completion date of the treatment after the temperature rises rapidly to ≥70°C on the first day; alternatively, the fermentation tank is divided into a plurality of compartments, each of them is equipped with a blower, and both the air feed time and air feed halting time for each of the blowers may be controlled so as to satisfy the above-mentioned temperature conditions.
