Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention is further described in detail. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] A kind of organic fertilizer aerobic fermentation method that utilizes film covering automatic control, comprises the steps:

[0023] Step a. Selection of fermentation site: Use cement or asphalt ground as the fermentation site. The fermentation site is a concrete structure with three walls and an open top, which can effectively increase the amount of material accumulation and treatment, and can prevent leakage and collect leachate. In said step a, the width of the fermentation site is 8m, there are 2 ventilation channels, and the fermentation site is inclined to the entrance with a slope of 2%, so that the leachate can flow out and collect. The wall of the ferm...

Abstract

The invention discloses an organic fertilizer aerobic fermentation method capable of being automatically controlled by utilizing film covering. The organic fertilizer aerobic fermentation method comprises the steps of selecting a fermentation field, digging a ventilation duct, building a heap, covering a film, fermenting and the like. According to the organic fertilizer aerobic fermentation method, a film covering type system, a ventilation system and a control system complement each other to form a unique, economical and effective high-temperature aerobic fermentation system; the method can help the film covering type system to keep temperature, and oxygen concentration and temperature in a material heap are uniformly distributed; a whole heap body can easily reach a temperature conditionof killing pathogens; the concentration of ozone can be reduced by 90 percent to 97 percent and the content of microorganisms in exhausted gas is reduced by 99 percent or more, so that the health ofon-site staff and nearby residents can be protected.

Description

technical field [0001] The invention relates to the technical field of aerobic fermentation, in particular to an aerobic fermentation method for organic fertilizers controlled automatically by film covering. Background technique [0002] In today's era that attaches great importance to food safety, green food is very popular. The disadvantages of the traditional mode of growing crops by using a large amount of chemical fertilizers are becoming more and more obvious. Organic fertilizers have become the leading role of fertilizers in the new era, and the organic fertilizer industry has become an emerging sunrise industry. Aerobic fermentation of organic fertilizer refers to a fermentation process that relies on aerobic microorganisms to biodegrade organic matter in an aerobic environment. Aerobic microorganisms rely on their own life activities to convert organic matter in fermentation materials into CO 2 , humus and heat etc. Aerobic microorganisms can directly absorb and ...
