Description

technical field [0001] The invention relates to the field of solid waste recycling, in particular to a resource recycling treatment system and method for anaerobic fermentation biogas residue. Background technique [0002] In recent years, facing the demand for renewable energy and the thorny problem of organic waste treatment, the use of anaerobic fermentation technology to treat organic waste has attracted more and more attention. Anaerobic fermentation refers to the production process of using facultative bacteria and obligate anaerobic bacteria to use organic matter as its own nutrient source and transform organic matter into biogas and biogas fertilizer through physiological metabolism under anaerobic or hypoxic conditions. The biogas produced by anaerobic fermentation is a clean and renewable energy that can be used to generate electricity and heat, thereby achieving a win-win situation for the environment, energy and resources. However, with the development of biogas...

Problems solved by technology

Moreover, if the biogas residue after anaerobic fermentation is not properly disposed of, the organic matter, nitrogen, phosphorus, and pathogenic microorganisms in the biogas residue will enter the environment, which will lead to secondary pollution of the environment and waste of resources. , Harmless resource treatment has become a bottleneck restricting the development of anaerobic fermentation engineering

At present, although there are many ways to recycle biogas residues, the output of biogas residues is large and the processing cost is high. These methods are not enough to absorb the amount of anaerobic fermentation biogas residues at the present stage.
