STRABAG manufacturers believe that under anaerobic conditions, the use of natural microorganisms or inoculated microorganisms to convert organic matter into carbon dioxide and methane gas is called anaerobic digestion. This method has the advantages of low energy consumption, less residual sludge and energy recovery. In recent years, dry anaerobic digestion technology has been actively developed and applied in developed countries, especially in Europe, and will become one of the directions of organic solid waste treatment in the future.

　　STRABAGThe manufacturer thinksAnaerobic fermentation refers to the redox process that uses the intermediate metabolites of organic matter oxidation and decomposition as electron acceptors in the absence of external electron acceptors. From the perspective of environmental governance, fermentation refers to anaerobic microorganisms and facultative anaerobic microorganisms in a good growth environment, through metabolic physiological functions, the substrate(The biodegradable part of sewage or organic solid waste) is converted into inorganic matter and its own cell material, so as to achieve the purpose of harmless and resource process. Due to the complex composition of organic solid waste, containing a large number of microorganisms, the reaction in the anaerobic fermentation process is very complex, involving a variety of biochemical reactions and physical and chemical equilibrium processes.

　　STRABAGThe manufacturer thinksCompared with wet anaerobic digestion, dry anaerobic digestion of organic waste has many advantages and benefits, but there are still many difficulties in popularization and application. First, the high concentration of the reaction matrix makes it difficult for intermediate products and energy to transfer and diffuse in the medium, thereby forming a feedback compression. Secondly, the structure, composition and particle size of the reaction matrix are not uniform, which makes the operation of the system difficult to control and unstable. Third, the stirring resistance is large, and it is difficult to stir the mixed matrix.

STRABAGThe manufacturer thinksAnaerobic fermentation, as a green energy production technology with comprehensive environmental benefits, can not only alleviate the pollution of the environment caused by the large amount of waste produced by production, but also convert the waste organic matter into energy for people to use, that is, biogas. The main components of biogas are methane, carbon dioxide and hydrogen.

STRABAGThe manufacturer thinksMethane and hydrogen have the potential to replace traditional energy sources and are of great significance to the development of renewable energy. In addition, biogas is an environmentally friendly energy source, and its use can reduce environmental pollution. The residue of biogas slurry after anaerobic fermentation can be used as organic compound fertilizer to realize fertilizer utilization. Due to rich nutrients(such as phosphorus, carbon, nitrogen and other large elements and potassium, magnesium, iron, calcium and other trace elements), when biogas slurry is used as fertilizer, these nutrients are conducive to the improvement of soil fertility, so as to promote the growth of plants.

These are some knowledge points about dry anaerobic fermentation. I hope you can seriously study and understand the relevant knowledge and choose the products and equipment suitable for your needs.
