Method, device and system for removing odor during aerobic fermentation of livestock and poultry excrement

Abstract

The invention belongs to the technical field of deodorization, and discloses a method, device and system for removing odor during aerobic fermentation of livestock and poultry excremen, which comprises the following steps: a spraying facilities arranged on the upper part of a fermentation tank is used for simultaneously spraying acidic substances to reduce the odor release or cover the odor duringthe rolling and pushing process; a slideable film is arranged between the roof of a fermentation workshop and a turnover machine, the release odor is bioremoved by a composite microbial layer contained in the middle; a rotary focusing solar energy device is arranged on the roof of the fermentation workshop, the odor is decomposed by the decomposition action of the light energy. The device for removing odor during aerobic fermentation of livestock and poultry excrement utilizes the strong oxidizing property of the ferrate to destroy the cell wall, the cell membrane and the enzyme in the cell structure, can kill the microorganisms in the livestock and poultry excrement, thereby fundamentally inhibiting the generation of the odor; the biological removal is adopted in the most severe stage ofthe release amount of the odor by the sliding film, the odor is decomposed by means of a device capable of rotating and focusing the sunlight energy, and the odor is decomposed by the decomposition action of the light energy through the rotary focusing solar energy device; and the odor efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of deodorization, and in particular relates to a method, device and system for removing odor during the aerobic fermentation process of livestock and poultry manure. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Livestock and poultry manure has always been regarded as an important source of soil fertilizer, so most of the livestock and poultry manure is applied on the spot. According to statistics in 1976, at that time more than 1 / 3 of the fertilizers in my country's agricultural production were provided by animal manure. Animal excrement is rich in organic matter and nutrients such as nitrogen, phosphorus, and potassium, and can also supply calcium, magnesium, sulfur, and other minerals and trace elements required by crops to meet the needs of various nutrients during the growth of crops. need. Excessively concentrated animal h...

Problems solved by technology

[0005] The current removal of poultry manure odor is slow; at the same time, the removal efficiency is low

[0006] The degree of control is poorly intelligent

[0007] The existing technology cannot effectively remove a large amount of odor generated during the fermentation process of livestock and poultry manure
