| titleOfInvention | A method for strengthening the anaerobic digestion of urban sludge to produce methane by using a filter screen structure |
| abstract | The invention relates to a method for strengthening the anaerobic digestion of urban sludge to produce methane by applying a filter screen structure. The method includes a filter screen structure with titanium or titanium alloy as skeleton and ferric tetroxide as coating in the anaerobic digestion system, Accelerate the rate of sludge hydrolysis and acidification and increase the proportion of methane in biogas. Compared with the prior art, the present invention increases the contact between ferric oxide and anaerobic microorganisms through the network structure; and, the stable crystal structure of ferric tetroxide ensures the continuity of the electron carrier and enriches the electrical activity at the same time. Microorganisms; titanium or titanium alloys, as materials with high strength, corrosion resistance, good biocompatibility and good electrical conductivity, can form a good match with ferric tetroxide, and assist in promoting the transfer process of electrons; the invention has the advantages of low cost, high The advantage of income is that there is no need for repeated dosing, and the effect is stable. It can strengthen the oxidative decomposition of organic matter in the process of anaerobic digestion, accelerate the rate of methane production, and increase the gas production. |
