沼气是生物质如秸秆、杂草、树叶、人畜粪便等废弃物,在一定温度、湿度、酸碱度和隔绝空气等条件下,经微生物发酵所产生的可燃性气体,它是生物能源之一。用生物质发酵法制取沼气,既可解决某些地区如农村缺燃料的问题,又可改善环境卫生,对提高肥料质量以及发展农业生产等都具有重要意义。现在我们试试怎样来制取它。 Biogas is a combustible gas produced by microbial fermentation under the conditions of certain temperature, humidity, pH, and isolated air, and it is one of bio-energy sources, such as biomass, straws, weeds, leaves, and human and animal wastes. Biogas production from biomass fermentation method can not only solve the problem of fuel shortage in some areas, such as rural areas, but also improve environmental sanitation, which is of great significance for improving fertilizer quality and developing agricultural production. Now let’s try how to make it.
