摘　　要：实验的目的旨在研究厌氧消化系统VS产气率的变化规律。厌氧消化试验在中温条件下进行,以餐厨垃圾为实验底料。实验过程中对沼气产率、VS产气率、甲烷含量等指标进行监测。研究结果显示:厌氧系统在半连续方式下运行VS产气效率明显高于同等反应条件下的批式系统。系统的运行状态与VS产气率有直接对应关系,当系统出现抑制状态时,VS产气率出现显著下降。当系统在恢复过程中,VS产气率明显提高。The aim of this work is to Research Variation volatile solids(VS)biogas production rule.In this paper,The quasi-continuous anaerobic digestion test was carried out at medium temperature.The monitoring indexes such as biogas production rate,vs gas production rate,total VFA,methane content and pH were tested.The results showed that anaerobic fermentation semi-continuous mode VS gas significantly higher than the number of system efficiency.When the inhibition of anaerobic digestion systems,VS gas efficiency of a certain degree of decline.When the system in the process of recovery,VS gas efficiency increased significantly.
