Embodiment Construction
[0029] The application mechanism of this two-phase anaerobic process based on magnetite and activated carbon enhancement is: 1. In an anaerobic environment, iron-reducing microorganisms can transfer the generated electrons to extracellular insoluble ferric iron while metabolizing organic matter. substances (such as magnetite), so that Fe 3+ is reduced to Fe 2+ ——Reduction process of dissimilated iron. The dissimilatory iron reduction process can provide growth support for iron-reducing microorganisms, and then enrich iron-reducing microorganisms. Iron-reducing microorganisms have the ability to decompose macromolecular complex organic substances (such as sugars, proteins and lipids, etc.). In addition, the acidic anaerobic environment (pH<7.0) is thermodynamically favorable for the reduction process of dissimilated iron.
[0030] 2. Adding conductive carbon materials to anaerobic sludge can build and strengthen DIET—a new mechanism of microbial intertrophy metabolism that c...
