| 摘 要： | 探讨了将德国电能需求导向沼气供应模式应用于中国污水厂的剩余污泥和餐厨垃圾协同厌氧发酵系统，以实现根据污水厂电能需求即时调控沼气输出，从而提高沼气利用效率的目的.首先综述了电能需求导向的沼气供应模式在国内外的研究进展，在此基础上提出了一种新型的电能需求导向沼气供应模式实现情景，并利用系统动力学模型模拟了沼气生产及发电系统在此情景下的运行，通过系统的净现值作为观测指标与传统的实现情景进行对比以验证其经济性优势.最后，选取我国某污水厂为典型案例验证了本研究所提出模型，并总结了本研究的不足，为进一步研究奠定了基础.

| Abstract: | This paper explores the feasibility of applying the demand-oriented biogas supply (DOBS) scheme in Chinese sewage treatment plants using excess sludge and food waste co-digestion to produce electricity.With instantaneous regulating capabilities, the DOBS scheme provides better biogas utilization efficiency.We first reviewed the current research progress of the DOBS system, followed by proposing an improved DOBS implementation scenario.A system dynamic model is then developed to simulate the biogas production and electricity generation.Net present value (NPV) of the system is selected as an economic indicator to assess the performance of the proposed scenario compared with the traditional DOBS scenarios.A typical Chinese sewage treatment plant is selected as a case study to validate the proposed combined model, and limitations of the model are evaluated. |
