How does pig manure organic fertilizer equipment produce organic fertilizer? With the strengthening of national environmental protection and governance, the emergence of pig manure organic fertilizer equipment, the implementation of national circular economy policy, and the attention of social development to the industry, the treatment methods of large-scale pig manure are also changing. In the past, it was mainly ecological use, and pig manure was directly returned to the field. However, with the development of biological fermentation technology, the use of organic fertilizer equipment to produce pig manure organic fertilizer has become a new measure. The pig manure organic fertilizer equipment produces organic fertilizer from pig manure by aerobic fermentation, with a large amount of ammonia nitrogen generated. The whole fermentation process is in an alkaline environment, making pH rise. The adverse effect of high pH environment is mainly to increase nitrogen loss. It can add sawdust, rice straw, chaff and other auxiliary materials, reduce the mineralization rate of nitrogen in the main material during the fermentation process, promote the biological fixation of nitrogen, and reduce the volatilization loss of ammonia nitrogen.
So how does pig manure organic fertilizer equipment produce organic fertilizer?
The main environmental factors affecting fermentation are temperature, water, C/N and pH. During the fermentation of pig manure, human control is used to create a suitable environment for aerobic microbial activities and promote the rapid fermentation.
Pig manure organic fertilizer equipment uses high-temperature airtight equipment to treat pig manure, and carries out biological fermentation under the action of adding active bacteria to release nutrients. After fully decomposing the organic matter in it, the formed bio-heat and high-temperature fermentation process can kill bacteria and eggs, purify the environment, detoxify and deodorize, and produce high-efficiency high-quality organic fertilizer and organic-inorganic compound Hefei, which can be transformed into resources and industrialization through harmless treatment. Fermented organic fertilizer can improve soil aggregate structure and soil fertility, which is beneficial to improve crop yield and quality.
