多元原料混合发酵制备沼气技术研究进展

摘要

So far, livestock manure and agricultural straws are the main biogas production raw materials in China. With the development of anaerobic digestion technology, more types of waste have gradually drawn our attention. As a kind of renewable energy resource, various biomass materials are of great significance for biogas production in the construction of ecological civilization in China. In this paper, we reviewed the characteristics of biomass resources in China, such as livestock manure, crop straw, agricultural products processing waste, municipal organic waste and energy crop, and the advantages and disadvantages of them as biogas fermentation raw material, then compared the biogas potential of these raw materials. The anaerobic digestion technology of mixed raw materials and some important exogenous additives which can promote biogas production were discussed.%目前，我国沼气的发酵原料主要是禽畜粪便和农作物秸秆，随着厌氧发酵技术的发展，更多种类废弃物也逐步受到人们的关注。有机废弃物沼气化利用在我国生态文明建设中有着重大意义。论文综述了我国生物质资源，如禽畜粪便、农作物秸秆、农产品加工废弃物、市政有机废弃物和能源作物的特性和作为沼气发酵原料的优缺点，比较了这些原料的沼气生产潜力，探讨了混合原料发酵技术及重要的几种沼气发酵外源添加剂。
