Fermentation bed pig deodorant, its mystery can be analyzed from the following aspects:
First, reduce pollution sources. Nitrogen is one of the main elements that cause environmental pollution in excreta. Nitrogen in excreta generally accounts for 2.0% to 6.0% of dry matter (33% in feces and 67% in urine). Livestock and poultry mainly through the diet intake of protein (protein 16% of the average nitrogen) state and other nitrogen, after digestion and absorption, the animal's body is deposited about 35%, and the remaining about 65% excreted. The NH3 and H2S in pig manure urine are mainly caused by the incomplete absorption or absorption of protein by pigs. The increase of protein utilization can reduce odor gas emissions. The pigs in the fermentation bed can make the protein discharged from the feces be further recycled because of the pig's arched food, thereby increasing the utilization rate of the protein and reducing the pollution source, that is, the discharge of pollutants has been “reducedâ€. Now.
Second, physical deodorization. The so-called physical method of deodorization refers to the adsorption of gas that produces a foul odor on the surface of a solid or liquid medium, making it difficult to disperse into the air. The bed of the fermentation bed consists of about 50 cm of sawdust (wood chips or rice husks, etc.). When a malodorous gas passes through between the wood particles, some of the odor components are absorbed by the wood chips or are dissolved by the moisture between the wood chips and the inherent moisture of the wood chips. The release rate of the odor component gas and the amount of released gas are slowed down, and the odor emission is controlled to some extent.
Third, chemical deodorization. Chemical deodorization is the use of specific chemical reactions to convert odorous harmful gases into non-toxic and harmless substances. Through physisorption, the malodorous gas is brought into contact with the fermentation mattress material gas-liquid to transfer the gas-phase odor component to the liquid phase, and the odor material is removed by the neutralization, oxidation or other reaction of the fermented material and the odor component. Including organic sulfides, nitrogen compounds, organic acids and a few oxygenated hydrocarbons. However, this method can only convert odor molecules into salts to facilitate absorption, and other methods must be used to destroy or recover the odor components.
Fourth, biological deodorization. Biological deodorization is the most important reason for the absence of odors in pigs fermented by fermented bed fermentation, and it mainly plays an important role in two aspects. 1 The starter contains more than 150 million beneficial functional bacteria per gram. After the start of fermentation, beneficial microorganisms multiply geometrically and rapidly. In this process, the excrement of pigs and the ammonium adsorbed on sawdust are exactly the same. Sulfur and other odorous compounds are digested and absorbed into protein and trace elements that can be eaten by pigs. With the constant progress of the fermentation process, the rapid propagation of functional microbes will digest and absorb malodorous substances more and more thoroughly. 2 Pigs have a habit of arching food. This habit can be fully utilized during the pig breeding process. The beneficial microorganisms in the starter feed enter the pig's digestive tract as the pig's arch feeds. Gastrointestinal beneficial microorganisms can not only inhibit some pathogenic bacteria activity, prevent diseases, but also inhibit the activities of harmful bacteria, such as inhibition of Welch bacteria activity, thus preventing the abnormal decomposition of proteins, thereby reducing the production of ammonia and helium. . These kinds of odorous substances are reduced, and the smell of pig manure is naturally reduced. In addition, beneficial microorganisms have higher activity of proteases, lipases, and amylase enzymes, which can enhance the decomposition of proteins, fats, and other substances. Not only do they improve the utilization and absorption rate of feed, they also promote the growth of livestock and poultry, and they also reduce odors. The production of material.
