| 摘 要： | 利用厌氧干发酵技术处理固体有机废物与传统的湿发酵相比具有许多优势,但厌氧干发酵机制的研究存在许多困难,在一定程度上限制了厌氧干发酵技术的发展。文章在对国内外研究现状进行文献调查后,总结概括了厌氧干发酵理论模型从"两点模型"和"区反应模型"到"浓度波扩散模型"和"反应前沿假说"的发展进程,讨论了其各自特点和对厌氧干发酵机制研究的意义以及其不完善之处;并分别从微生物生长、底物水解和生物气产生三个方面综述了近年来国内外对厌氧干发酵动力学的研究进展。然而,目前的研究仅是针对某些物料进行的特异性研究,还没有一个普遍适用的关于有机固体废弃物厌氧干发酵的理论模型被发展出来,因此对干发酵传质传热机制的探索和数学模拟成为当前对于干发酵机制研究的主要方向。

| Abstract: | With its many advantages over the conventional anaerobic digestion regarding solid waste,dry anaerobic digestion has become a main technology applied in many countries to treat organic solid waste.Based on reviewing literatures,this paper summarizes the studies of mechanism regarding three different theoretical models and the reaction front hypothesis of dry anaerobic digestion and the kinetics are related too with respect to microorganism growth,hydrolysis of substrate and biogas production.Problem to be resolved in the future,as pointed by the author,is to develop a kind of model that could be universally applicable with focus on heat transfer mechanism of dry anaerobic digestion. |
