The invention belongs to the technical field of
waste recycling in the field of environment, and particularly relates to an in-situ reduction method for kitchen wastes in residential communities. The method includes the steps: using
landscaping wastes in the residential communities as
dry basis auxiliary materials, using kitchen wastes in the residential communities as treatment materials, and feeding the
landscaping wastes and the kitchen wastes into a closed
compost reactor for well mixing; conditioning the
mixed materials; adding microbial activity matrix used as a
microorganism source for starting of composting, and performing
reduction treatment by means of intermittent aerobic dynamic
compost; using a draft fan for air drafting of the closed
compost reactor to realize ventilation and
aeration of materials; and regularly feeding and discharging every day, sieving the discharged materials, and on-
sieve materials rich in
microorganism floras flows back to the compost reactor, so that continuous and efficient composting reduction of kitchen wastes is realized. The method has the advantages of low
energy consumption, low cost, high treatment efficiency, small occupied area and evident reduction,
waste recycling is realized, and domestic garbage treatment pressure can be relieved.
