沼气物料一般有农作物秸秆、饲草、树叶、粪便等,秸秆中的木质素、纤维素、半纤维素、果胶和蜡质等化合物如果没有经过处理破坏,容易结壳、影响产气量和产气效率。沼气物料预处理主要有如下作用:1.缩短产气时间。秸秆难于消化,其中的木质素、纤维等很难被分解,因而事先将秸秆用金宝贝沼气物料速 Biogas materials are generally crop stalks, forage grass, leaves, feces and so on. The lignin, cellulose, hemicellulose, pectin and wax compounds in straw are easy to crust if they have not been treated and destroyed, affecting gas production and production Gas efficiency. Biogas material pretreatment has the following main effects: 1. Shorten the gas production time. Straw is difficult to digest, of which lignin, fiber and other difficult to be decomposed, so prior to the use of corn stalks biogas material speed
