Anaerobic digestion (AD) of solid wastes is an efficient and economical alternative to convert complex organic matter into clean energy. Effectiveness of AD depends on different physio-chemical characteristics of solid wastes. In the present study, an attempt is made to develop an anaerobic digestability index (ADI) which will indicate the biodegradability of solid wastes. Based on a literature review 26 parameters were first identified to be influencing the AD which were narrowed down to 11 using the Delphi method. A participatory-based technique (analytic hierarchy process) was then adopted for assigning weightages to the selected parameters. Rating curves for the selected parameters were drawn with expert opinion using the Delphi method. Based on the sensitivity analysis, weighted additive function was selected for aggregating the subindex with the relative weightages. ADI was then applied to different types of solid wastes proving it to be a robust index for determining the anaerobic digestability.

有机固体废物厌氧消化率指数的制定


固体废物的厌氧消化（AD）是将复杂有机物转化为清洁能源的有效且经济的替代方案。 AD 的有效性取决于固体废物的不同理化特性。在本研究中，试图开发一种厌氧消化指数（ADI），该指数将表明固体废物的生物降解性。根据文献综述，首先确定了 26 个影响 AD 的参数，使用德尔菲法将其范围缩小到 11 个。然后采用基于参与式的技术（层次分析法）为所选参数分配权重。所选参数的评级曲线是使用德尔菲法根据专家意见绘制的。基于敏感性分析，选择加权相加函数将分项指数与相对权重进行聚合。然后将 ADI 应用于不同类型的固体废物，证明它是确定厌氧消化率的可靠指标。
