摘要
以牛粪、猪粪和玉米秸秆为发酵原料,研究多原料混合发酵产甲烷的最佳配比,并利用冈珀茨模型(Gompertz model)分析不同原料配比混合发酵产甲烷的动力学特性。结果显示牛粪、猪粪和玉米秸秆三者混合的产甲烷效果优于牛粪或猪粪与玉米秸秆两者混合的发酵效果,且在牛粪、猪粪、玉米秸秆干物质的质量配比为1.5∶1.5∶1时,混合发酵的产甲烷量和产甲烷速率最高,分别为10114.71 m L和536.14 m L/d。
In this paper,cow manure,swine manure and com straw are mixed with different proportions,and GompertzModel is carried out to regression analyse biogas production from mixture. The biogas production rate,cumulative biogasyield and methane content are tested. The results indicated that the methane potential under co-digestion of threematerials performed is better than two components and the optimized dry weight rate of cow manure,swine manure andcom straw is 1.5∶1.5∶1,the cumulative methane and methane production rate are expected to 10114.71 m L and536.14 m L/d.
