A method for promoting biogas production using site-specific anaerobic digestion booster and its dosing system

摘要

The present invention relates to a method and apparatus for biogas production using biomass using an on-site customized anaerobic digestion promoter, which reduces the toxicity of a substrate in an anaerobic digestion process for promoting biogas production to improve the biodegradation of organic compounds, The field-customized anaerobic digestion accelerator according to the present invention is composed of a mixture of magnesium oxide (MgO), ferric chloride (FeCl ₃ ) and cellulase, and the magnesium oxide MgO) and ferric chloride (FeCl ₃ ) are calculated from the excess sulfur (S) and excess phosphorus (P) contained in the substrate by the following equations. The present invention has the effect of being utilized as a working guide line for efficiently improving the production of biogas in an anaerobic digestion facility. CFeCl ₃ = Se × (325/96) CMgO = Pe x (40/31) (Where, CFeCl ₃ is the amount of ferric chloride, CMgO is the amount of magnesium oxide, Se is excess sulfur (S), Pe is excess phosphorus (P), and each unit is mg /
