沼气工程可分为沼气制取工程、沼气精制工程和沼气利用工程三部分。该论文从微生物生命科学和沼气制取工程的相互关系角度,较系统地阐述了沼气自然产生的条件和机理对沼气制取工程中相关的新技术和新方法的产生与发展的影响,包括发酵原料、发酵工艺、制取装置设备及沼气检测等,并对国外的沼气新工艺和新技术作了简要介绍。论证结果表明沼气经济高效制取技术的产生和发展与微生物生命科学的进步息息相关。
Biogas projects can be divided into biogas production project, biogas purification project and biogas utilization project three parts. The paper systematically expounds the effects of natural conditions and mechanism of biogas on the generation and development of new technologies and methods related to biogas production from the perspective of the relationship between microbial life sciences and biogas production engineering. Raw materials, fermentation technology, equipment and biogas detection system, and made a brief introduction of new biogas technologies and technologies abroad. The demonstration results show that the production and development of biogas economically efficient extraction technology are closely related to the progress of microbial life science.
