本文研究了不同有机废弃物混合对厌氧消化过程的影响。牲畜粪便和有机固体废物已被考虑作为基质，以验证它们的混合是否会提高甲烷生产率和降低工艺失败的风险。利用布法罗粪便（BM）、家禽粪便（PM）、城市固体废物有机组分（OFMSW）、蔬菜废物（GW）以及由BM和OFMSW组成的两种不同混合物进行了生物甲烷潜力（BMP）测试。将BM与OFMSW混合分别在从测试开始的30天和15天后导致甲烷体积增加12%和30%。实验数据也已被用来校准和验证的数学模型，作者先前提出的，显示其能力，以再现协同效应的甲烷生产促进共消化BM和OFSMW。
This paper deals with an experimental study aimed at assessing the effect of mixing different organic wastes on the anaerobic digestion process. Livestock manure and organic solid wastes have been taken into account as substrates to verify if their mixing gives rise to higher methane production rates and lower risk of process failure. Bio-methane potential (BMP) tests have been conducted using the following substrates: buffalo manure (BM), poultry manure (PM), organic fraction of the municipal solid waste (OFMSW), greengrocery waste (GW) and two different mixtures composed of BM and OFMSW. Mixing BM with OFMSW resulted in 12% and 30% higher methane volumes after 30 and 15 days from the test start, respectively. Experimental data have been also used to calibrate and validate a mathematical model previously proposed by the authors, showing its capability to reproduce the synergistic effect on methane production promoted by co-digesting BM and OFSMW.
