Layered parallel translation type solid organic waste biological treatment bed, and application method thereof

Abstract

The invention discloses a layered parallel translation type solid organic waste biological treatment bed. The layered parallel translation type solid organic waste biological treatment bed, and applications thereof comprises a layered frame; each layer of the layered frame is provided with a transmission belt, and a transmission device which is connected with the transmission belt via transmission connection; the two sides of each transmission belt are provided with raised skirt edges. The invention also discloses an application method of the layered parallel translation type solid organic waste biological treatment bed. According to the application method, solid organic waste is delivered into a premixer, and plant material powder and hermetia illucens larvas are delivered into the premixer; an obtained mixture is subjected to transformation for 1 to 2 days on the layers, and then discharging is carried out so as to collect the mixture by a container under the layered frame. The layered parallel translation type solid organic waste biological treatment bed is capable of reducing occupied area, increasing treatment efficiency, shortening treatment cycle, reducing energy consumption, and is convenient for operation and maintenance; treatment is complete; and no secondary pollution is caused.

Description

technical field [0001] The invention relates to an organic waste biological treatment bed, in particular to a layered translational solid organic waste biological treatment bed and application thereof. Background technique [0002] Kitchen waste comes from human food and is rich in various nutrients. It is a biomass resource that has been misplaced. Therefore, it is the most ideal way to convert it into feed raw materials. Currently, the following methods are commonly used: [0003] High-temperature aerobic composting: High-temperature aerobic composting is one of the effective ways to deal with kitchen waste. Composting is the process of biologically stabilizing organic solid waste under artificially controlled conditions. Food waste has high organic content, comprehensive nutrients, and low C / N ratio. It is a good nutrient for microorganisms and is very suitable for composting raw materials. At the same time, the content of inert waste (such as waste plastics, etc.) in ki...

Problems solved by technology

During the 2000 Olympic Games in Sydney, Australia, 40 million earthworms were used to dispose of domestic waste in the Olympic Village, and the waste could be disposed of on the spot without leaving the village. As far as the technology itself is concerned, earthworms can only swallow decomposed organic matter, so fresh organic waste cannot be processed, and the composting process will inevitably produce corruption and odor, which limits its application to some extent. In addition, earthworm species The degradation and separation techniques of vermicompost are also constraints

[0007] Anaerobic fermentation: The anaerobic fermentation technology of food waste belongs to the mainstream technology in the world. It is characterized by large processing scale and high degree of mechanization. It can process hundreds of tons of food waste at a time. It is especially favored by the municipal management departments of large cities. preference, and this technical system has a long history of development abroad, and there are many successful operation cases. However, the composition of food waste abroad is very different from that in China. The degree of classification of food waste in China is relatively low, and impurities are relatively It is very unsuitable for the growth of anaerobic microorganisms. Therefore, the equipment and technology directly imported from abroad are often not acclimatized in China and difficult to operate. A typical example is the garbage in Dongcun, Beijing. The treatment plant cost 300 million yuan, but the equipment and technology imported from Germany could not operate normally. After five years of commissioning, it is still idle, causing a lot of waste. In addition, the one-time investment equipment for anaerobic fermentation technology is expensive and takes up a lot of space , The treatment cycle is long, the generated biogas lacks a mature supporting application system, it is difficult to realize the market value, and there are also problems in the outlet of biogas slurry and biogas residue, so the application of this technology is difficult to promote in China
