METHOD FOR PREPARING AEROBIC COMPOST HAVING KITCHEN WASTE ORGANIC MATTERS

摘要

Disclosed in the present invention is a method for preparing an aerobic compost having kitchen waste organic matters: 1) classifying kitchen waste; 2) forming a compost pre-mix; 3) laying a layer of conditioner in a compost tank, pouring the compost pre-mix on top of the laid conditioner; 4) piling to form a strip heap; 5) covering with a waterproof breathable film; 6) starting a primary aerobic fermentation for 20-40 days, so as to obtain a fermentation residue and collect a fermentation leachate; 7) transferring the fermentation residue to a crude crushing system so as to undergo a crude crushing treatment; 8) transferring the material to a fermentation tank, repeating steps 4) and 5), spraying back the fermentation leachate, and starting a secondary aerobic fermentation for 7 days-20 days to obtain the compost. The method for preparing an aerobic compost having kitchen waste organic matters according to the present invention eliminates a pre-treatment step, and uses kitchen waste organic matters which have been waste classified directly for composting. The step of crude crushing is moved to after the aerobic fermentation, and the fermentation leachate is collected and sprayed back. The method can reduce the treatment quantity to be handled by the crude crushing system, which may shorten the fermentation time, and reduce the generation of odors.
