组合赋权法及ELECTRE-Ⅰ法在调控沼气发酵工艺中的应用
|
摘要
厌氧发酵生产沼气就是将有机废弃物"变废为宝",达到减量化、无害化和资源化的目的,减少资源浪费及生态破坏。根据生物质特性、反应条件及其他因素构建了评价体系的一级指标,选取总固体浓度、碳氮比(C/N)、反应温度、p H值及外源添加剂作为二级指标,采用层次分析法(AHP)及熵权法相结合的组合赋权法确定了各二级指标的权;构建了基于ELECTRE-I法厌氧发酵参数优选模型,并优化沼气发酵的工艺参数,为科学调控沼气发酵工艺参数提供了理论依据。
Production of biogas by anaerobic fermentation means to turn organic waste into treasure,which can achieve the purpose of reduction,harmless and resource utilization,and finally reduce waste of resources and ecological damage. The primary index of evaluation system was constructed from characteristics of biomass,reaction conditions and other factors. The total solid concentration,C/N,reaction temperature,pH value and exogenous additives were selected as the secondary indexes. The weight of each secondary index was determined by combination method of AHP and entropy weight. Optimization model of anaerobic fermentation parameters based on ELECTRE-1 method was established,and process parameters of biogas fermentation were optimized,which provided a theoretical basis for scientific control of biogas fermentation process parameters.
