我国十多年在农村发展沼气的经验表明,沼气是一个既受本身技术发展也受各种社会因素影响的综合性事业。决定沼气兴衰的主要因素是其自身的技术进步和它所产生的经济效益。本文仅就我国目前农村小型沼气的技术和经济现状及可能发展的前景进行讨论。 The experience of developing biogas in rural areas for more than a decade in our country shows that biogas is a comprehensive enterprise that is not only affected by its own technological development but also affected by various social factors. The main factor determining the rise and fall of biogas is its own technological advancement and the economic benefits it generates. This article only discusses the current technical and economic status of small-scale biogas in rural areas in our country and the prospect of its possible development.
