随着我国经济、社会的高速发展,农村、乡镇、城市的有机废弃物增长迅速,每年约产生60亿吨,已成为水体、空气、土壤的重要污染源。与此同时,大量化石能源消耗导致环境污染加剧、雾霾天气频发,严重影响了社会、经济的可持续发展。利用厌氧发酵技术将有机废弃物转化为生物燃气(沼气)是解决上述问题的有效手段。生物燃气的主要成分是甲烷,据估算,我国每

With the rapid economic and social development in our country, the organic waste in rural areas, towns and cities has been growing rapidly, generating about 6 billion tons annually and has become an important source of pollution for water, air and soil. In the meantime, a large amount of fossil energy consumption has led to the aggravating of environmental pollution and the frequent smog and haze weather have seriously affected the social and economic sustainable development. The use of anaerobic fermentation technology to convert organic waste into biogas (biogas) is an effective solution to the above problems. The main component of biogas is methane, it is estimated that China each
