The invention discloses a synergistic method in an anaerobic fermentation process. The anaerobic fermentation process not only can make solid waste reduced, recycling and harmless, but also can obtainclean energy methane which can be used. The method utilizes self-prepared magnetic biochar, adds the magnetic biochar in the process of co-fermentation of kitchen waste and excess sludge, and can significantly improve the methanogenesis efficiency and recycle the magnetic biochar compared with conventional non-medium feeding fermentation. The advantages of the invention patent are mainly embodiedin that: 1, the magnetic biochar can be recycled after fermentation; 2, the magnetic biochar is prepared from solid waste so as to realize solid waste recycling; and 3, the effect is remarkable and methane yield is improved.
Description
technical field [0001] The invention belongs to the technical field of environmental engineering, in particular to a synergistic method for anaerobic fermentation. Background technique [0002] When dealing with solid waste, the use of anaerobic fermentation technology can realize the reduction, recycling and harmlessness of solid waste, and can obtain biogas energy for reuse in life, and the most valuable component in biogas is methane , accounting for about 50%-70%, is a high-quality gas fuel. In the prior art, in the synergistic research of anaerobic fermentation, the main method is to add biochar, GAC and other non-bioconductive materials to realize the synergistic effect of the anaerobic fermentation system, but the medium added in this method is Effective recycling cannot be carried out after the reaction is completed, resulting in waste of materials. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the obje...
