摘　　要：以4种不同厌氧消化工艺为研究对象,选择发酵温度、水力停留时间和有效容积产气量作为优选厌氧消化工艺的评价因子,对模糊综合评价方法在优选厌氧消化工艺中的可行性进行分析,并应用模糊数学综合评价法中构造隶属度函数的方法对4种厌氧消化工艺进行浅析、优选评价,级别越低表示工艺越优异。结果表明,A工艺为二级,C工艺为三级,B和D工艺为四级。Based on the four anaerobic digestion process, three factors, namely, the anaerobic temperature, hydraulic reten- tion time and the effective volumetric biogas production rate, were chosen as indices for evaluating the feasibility of fuzzy synthesized assessment and optimizing of anaerobic digestion process. The construction membership function in the assess- ment was adopted to evaluate the optimizing level quantitatively, which was the lower the better. And the optimizing level of A, B, C, D anaerobic digestion process were level 2, level 4, level 3, and level 4, respectively.
