Embodiment Construction

[0014] See attached figure 1 , figure 2 with image 3 Shown, the present invention is further described, and the present invention is realized through the following steps:

[0015] The first step is to pre-treat organic solid waste. According to the nature of organic solid waste and fermentation requirements, the organic solid waste is sorted, crushed, mixed with auxiliary materials, recycled materials, strains, etc., and the moisture, C / N, particle size, porosity, etc. are adjusted to make the organic solid waste The pretreated material meets the fermentation requirements.

[0016] The second step is to build a membrane covering the stack of high-temperature aerobic fermentation strips. Use conveying equipment, such as conveyors, distribution machines, forklifts, etc., to transport the pretreated materials to the fermentation site, pile them into strips above the ventilation pipes in the fermentation area, and cover the material strips with waterproof and breathable memb...

Abstract

The invention relates to the technical field of organic solid waste processing, in particular to an organic solid waste film covering high-temperature aerobic fermentation method. The fermentation method is characterized in that the organic solid waste is pretreated; the pretreated material is piled in strip pile; the material strip pile is provided with a sensor and covered with a waterproof breathable film; a blower and an air-pipe under the material are used for supplying oxygen to the material; an intelligent ventilating control system is used for optimizing the fermentation process; after the material is fully decomposed, the waterproof breathable film on the material strip pile is removed, and then the material strip pile is transported into a clinker storing or processing area. Compared with the prior art, the fermentation method has short building period, few disposable investment, flexible construction, low operating cost, small odor influence, rain-proof, wind prevention and heat preservation effect and can protect the material from being affected by outside weathers.

Description

[technical field] [0001] The invention relates to the technical field of organic solid waste treatment, in particular to a film-covered high-temperature aerobic fermentation method for organic solid waste. [Background technique] [0002] With the rapid development of my country's social economy and urbanization, more and more organic solid wastes such as urban sewage treatment plant sludge, organic industrial wastewater sludge, livestock and poultry manure, and domestic garbage are produced. The high water content and high organic matter content in organic solid waste make it easy to rot and smell. In addition, it also contains a large number of pathogenic microorganisms, parasite eggs and heavy metals. If it is not treated effectively, it will damage the environment and pollute the water body. and soil, endangering human health. [0003] At present, the treatment and disposal methods of organic solid waste mainly include incineration, landfill, composting and throwing into...
