甲烷是重要的能源之一，但每年有3～4亿吨的甲烷从动植物生命活动过程、煤炭的采掘过程和天然气等排放到大气中。虽然人们早在100多年前就已经知道肥料和淤渣等废弃物的空气发酵，但最近世界各国从开发新能源以摆脱石油危机以及保持环境的角度出发，开始重新评价甲烷的有效利用 Methane is one of the important energy sources, but 300-300 million tons of methane are emitted into the atmosphere every year from the life and activity of animals and plants, the coal mining process and natural gas. Although air fermentation of fertilizers, sludge and other wastes has been known for more than 100 years, recently all countries in the world started to reevaluate the effective utilization of methane from the perspectives of developing new energy sources to escape the oil crisis and maintain the environment
