Abstract

The invention discloses an aerobic composting device and aerobic composting method for organic solid waste. The aerobic composting device comprises a composting bin, a fire-grate type feeding device, a screw rod extruding dehydration discharging device, an oxygen supply device, a leachate circulating spraying device, an exhaust pipe and a temperature measuring device, wherein the fire-grate type feeding device and the screw rod extruding dehydration discharging device are arranged in the composting bin; and the fire-grate type feeding device is positioned under the screw rod extruding dehydration discharging device. According to the aerobic composting device disclosed by the invention, a structure that the fire-grate type feeding device and the screw rod extruding dehydration discharging device are combined is used, through combination of gradation type feeding and screw rod dehydration discharging, the effects of high efficiency and favorable turning are achieved, materials are sufficiently and uniformly mixed, and the materials are loose; and the loose materials accelerate combination of oxygen in air with substrates, so that the oxygen supply efficiency is improved.

Description

technical field [0001] The invention relates to a treatment device and method for organic solid waste, in particular to an aerobic composting device and a composting method for organic solid waste. Background technique [0002] Organic solid waste includes kitchen waste, sludge from urban sewage treatment plants, straw, landscaping waste, etc. In the past, landfill and incineration were the main ways to deal with organic solid waste. Landfill could easily pollute groundwater, while incineration would seriously pollute the atmosphere. [0003] Microbial aerobic composting means that aerobic bacteria absorb, oxidize, and decompose waste under aerobic conditions. Through their own life activities, microorganisms oxidize part of the absorbed organic matter into simple inorganic matter, and at the same time release the energy required for the growth of microorganisms, while the other part of the organic matter is synthesized into new cytoplasm, so that the microorganisms continu...
