PROCESSES AND APPARATUS FOR PREPARING COMPOST

摘要

A process for preparing compost by inoculating an organic waste with a spawn for aerobic compost, characterized in that oxygen is supplied while agitating the waste and, in addition, water is supplied so th at the water content of the waste becomes 60 ~ 5 %; another process for preparing compost by inoculating an organic waste with a spawn f or aerobic compost, characterized in that, after the initiation of fermentation and before the migration of main fermentation to an amine-ammon ia metabolic system, a saccharide is added by portions to the waste; and an apparatus for preparing compost having: a fermentation tank provided with oxygen supply means, water spray means, and agitation means; and means for detecting or judging the water content of an organic waste within the fermentation tank and controlling the amount of water sprayed by the water spray means based on the results of the detection or judgement. In preparing compost having good quality by treating an organic waste discharged from a food processing plant and the like, the generation of ammonia and amines causative of emission of offensive odor and the formation of lower fatty acids as a growt h inhibitor of plants can be inhibited and the compost can be stably prepared in a short period of time.
