The invention discloses a
greenhouse film covering forced ventilation aerobic composting method which comprises the following steps of mixing rice and wheat straws, vines,
livestock and poultry excrement and
urine, perishable garbage and garden wastes in proportion, and putting the mixture into a composting
body space of a
greenhouse film covering forced ventilation aerobic composting
system for composting. According to the
system, a composting
body space is defined by an
expanded polytetrafluoroethylene film, a composting body side wall and a composting body ground, a ventilation groove is formed in the composting body ground, a
greenhouse framework is arranged above the
expanded polytetrafluoroethylene film and covers a plastic greenhouse film, and the plastic greenhouse film is providedwith an air inlet; the forced ventilation device extracts air from the space between the plastic greenhouse film and the
expanded polytetrafluoroethylene film and leads the air into the ventilation groove, and after 20 days of composting and when the temperature of the
compost is reduced to 50 DEG C or below, the expanded
polytetrafluoroethylene film is removed to enable the
compost to be exposedto the lower portion of the plastic greenhouse film. According to the method, turning and turning treatment is not needed during composting,
odor escaping in the whole composting process is circularly fed into the composting body through the forced ventilation
system, the deodorization and ventilation effects are achieved, and the overall operation cost is low.
