The invention belongs to the technical field of
solid waste resource treatment,
biomass resource treatment and ecological cycle economy, and discloses a family-type kitchen garbage biological circulation
processing system and method. Kitchen garbage on that day is collected, chopped and processed; the chopped kitchen garbage and wheat
bran are mixed according to the ratio being 1:1 to prepare flour
weevil larvae feed, and the feed is put into a flour
weevil larvae breeding box; and flour
weevil fecula sand is collected to make
organic fertilizer or potted
plant food. According to the family type kitchen garbage biological circulation
processing system and method, the kitchen garbage produced each day in a family is collected from the source to be converted into high-worth fecula sand and
polypide albumen through feeding of flour weevil, the fecula sand can serve as the
fertilizer to be applied to a balcony vegetable garden, and the garbage goes back to a kitchen and a dining-table through vegetable picking. The complex feeding habits of the flour weevil larval are used, and the kitchen garbage with the complex ingredient are eaten; meanwhile, insects do not urinate due to the special intestinal tract (malpighian
tubule) condition, the problem of environmental
pollution of the kitchen garbage in the flour weevil fecula
biotransformation process is effectively solved.
