Abstract

The invention provides a multi-compartment energy-saving aerobic composting device and a composting method thereof. The device comprises a crushing and mixing chamber, a multi-compartment fermentationand decomposition chamber, a leachate treatment layer and a leachate indication layer. Peculiar smell and flies are removed by filling lemon grass, wormwood, lavender, coconut residues, cinnamomum camphora sawdust and mature fertilizer; a high-quality composting space is created, materials are accurately added into the crushing and mixing chamber, and the C/N ratio of the composting materials iscontrolled from the source, so that the temperature and the humidity of a compost body can be effectively controlled in a natural aerobic ventilated environment to obtain a high-quality composting product, and mechanical turning and aeration are not needed. According to the invention, fermentation, decomposition and leachate treatment are integrated under a natural aerobic condition, peculiar smell and flies are not generated, the environmental safety is maintained, and the utilization rate of raw materials is improved by multi-compartment co-composting.

Description

technical field [0001] The invention belongs to the technical field of composting, in particular to a multi-compartment energy-saving aerobic composting device and a composting method thereof. Background technique [0002] With the promulgation of technical regulations and technical policies for domestic waste resource treatment in my country, at the same time, in order to improve the scientific management of urban decentralized waste composting treatment facilities, realize the in-situ harmless and reduction of organic waste (garden waste and kitchen waste) The traditional garden waste treatment methods are landfill and random stacking. These two treatment and disposal methods not only cause waste of resources, affect the appearance of the city, but also easily cause fire hazards, which can no longer meet the requirements of modern treatment. Kitchen waste has extremely high moisture and organic matter, and it is easy to perish and produce bad smell, but it can be transforme...
