How does dry spreading fermented bed deodorize?

Dry spreading fermented bed deodorization principle:

1, pollution source reduction: Nitrogen is one of the main elements in the excreta causing environmental pollution. Pig manure and urine NH3, H2S is mainly livestock and poultry into the body of the protein is not absorbed or absorbed incompletely produced, improve the utilization rate of protein can reduce the emission of malodorous gases. Dry spreading fermented bed farming technology can decompose the livestock and poultry manure into transformation, the protein discharged in the manure is further recycled, and then improve the utilization rate of protein, reducing the source of pollution.

2, biological deodorization: mainly plays an important role in two aspects.

(1) Each gram of the fermenter itself contains beneficial functional active bacteria, beneficial microorganisms are geometrically large and rapid reproduction after the start of the fermentation process, in the process of feces and urine excreted by pigs as well as adsorbed on the bedding ammonium sulfur and other malodorous compounds are digested and absorbed, and transformed into proteins and trace elements that can be consumed by livestock and poultry. As the fermentation process continues, the rapid multiplication of functional microorganisms will more and more thoroughly digest and absorb the malodorous substances.

(2) The beneficial microorganisms in the fermentation agent enter the digestive tract as the livestock and poultry eat the bedding. Beneficial microorganisms in the gastrointestinal tract not only inhibit some of the pathogenic bacterial activities to prevent disease, but also inhibit the activities of harmful bacteria, such as inhibiting the activities of Welsh bacteria, which prevents the heterogeneous decomposition of proteins, thus reducing the production of ammonia and indole. These several malodorous substances are reduced, and the odor of livestock and poultry manure is naturally reduced. In addition, beneficial microorganisms in protease, lipase and amylase enzyme activity is higher, can enhance the decomposition of protein, fat and other substances, not only can improve the utilization rate and absorption rate of feed, promote the growth of livestock and poultry, but also can reduce the production of malodorous substances.

3, chemical deodorization: chemical deodorization is the use of specific chemical reactions will have the odor of harmful gases into non-toxic and harmless substances. Through the physical adsorption of malodorous gases and fermentation mattress material gas-liquid contact, so that the gas phase odor components transferred to the liquid phase, and through the fermentation of fermentation bed fermentation substances and odor components of neutralization, oxidation, or other reactions to remove odor substances, including organic sulfides, nitrogen-containing compounds, organic acids and a small number of oxygen-containing hydrocarbons, and so on.

4, physical deodorization: that is, the odor producing gas adsorption on the surface of solid or liquid media, so that it is not easy to disseminate into the air. General dry spreading fermentation bed bedding is composed of 40 to 50 centimeters of sawdust (rice husk, straw, etc.), there are malodorous components of the gas through the sawdust particles, part of the malodorous components of the sawdust absorbed by the sawdust or by the sawdust between the moisture and sawdust intrinsic moisture dissolution, slowing down the release of malodorous components of the gas release speed and release of the amount of the odor to a certain degree of control of the odor emanation.

Dry spreading type fermented bed is the dry bedding raw materials and bacterial agent mixed evenly without adding water, not in advance of the fermentation, directly into the pig pen, immediately into the pig rearing method. Dry spreading fermentation bed pig technology is an eco-friendly pig mode, the key is to change the cement floor of pig pens into the ground with fermentation function.
