Solid organic waste composting device and composting method thereof

Abstract

The invention discloses a solid organic waste composting device and a composting method thereof. The solid organic waste composting device comprises a barrel body and an arch-shaped cover connected with the barrel body, wherein the inside of the barrel body is divided into an upper part reverse-truncated-cone-shaped space region, a middle main body fermentation material region and a lower part liquid storage region; the fermentation material region and the liquid storage region are separated by a movable sieve plate; the upper part of the liquid storage region is provided with a spiral air inlet; the spiral air inlet is communicated with the fermentation material region through the liquid storage region; a liquid discharging pipe is arranged at the lower part of the liquid storage region;at least one ventilation pipe inserted into a pile body is arranged in the barrel body; ventilation holes are uniformly distributed in the ventilation pipe; the lowest point of the lower end of the ventilation pipe is positioned on the movable sieve plate; the upper end of the ventilation pipe is higher than the fermentation material region; a spiral air outlet is formed in the arch-shaped cover.The solid organic waste composting device and the composting method are applicable to the composting of dispersive solid organic garbage with poor morphological uniformity and difficult pile body temperature and humidity control; organic wastes in vast rural areas in China can be widely treated; the wastes can also be dispersively and recyclably utilized in fields; the nearby conversion of the organic wastes is realized.

Description

technical field [0001] The invention relates to the technical field of urban and rural organic waste composting equipment, in particular to a decentralized solid organic waste composting device and a composting method thereof. Background technique [0002] In view of the huge urban and rural organic solid waste resources in our country, if they are not used rationally, it will not only cause a great waste of resources, but also cause serious pollution to the environment, so we should insist on using as much resources as possible in the treatment of organic solid waste the principle of transformation. [0003] For rural kitchen waste, livestock and poultry manure from individual households, etc., where it is difficult to collect, and there is a need for fertilizer around the waste generation point, the aerobic composting technology can be used to absorb, oxidize, and decompose the above substances to a greater extent. break down. There are many factors affecting composting,...

Problems solved by technology

For the decentralized small-scale composting system, it is difficult to control the natural composting conditions. After a period of natural fermentation, most of them are composted in the open air. The process is uncontrollable and will produce a lot of pungent odors and pollute the environment. This technology has been basically replaced by modern composting technology

Modern composting technology uses mechanized composting equipment, and through manual control, adjusts the parameters of the entire process of composting raw materials within an appropriate range to form a stable and uniform compost. However, organic solid waste in rural areas in my country cannot be effectively classified and collected. It is difficult to carry out standardized collection and processing

[0004] The existing related composting device (a kind of kitchen waste composting bin CN201811405441, open date 2019-02-15) has a good effect on the disposal of organic waste with good classification effect, but most of the domestic waste in rural areas in my country has not been effectively classified, solid The shape of the material is uncontrollable, which makes it difficult to control the oxygen permeability of the fermentation pile, and it is difficult to effectively discharge the water vapor generated by the fermentation, resulting in poor uniformity in the decomposition process of the organic fertilizer. effective regulation of
