| 摘 要： | 为实现牛粪与水稻秸秆资源化利用，采用批式试验，分别研究了预处理剂种类（H2O2、H2SO4、NaOH）、预处理剂浓度（2%、4%、6%）及牛粪与水稻秸秆物料比 （1∶1、2∶1、4∶1）对牛粪与水稻秸秆混合厌氧发酵产气效果的影响。结果表明，采用2% H2O2预处理剂，物料配比控制在1∶1，系统平均原料产气率为3980 mL·g-1，发酵效果最佳。动力学研究发现，一级动力学模型与Modified Gompertz方程均可较为准确地对牛粪与水稻秸秆混合厌氧发酵产气过程进行动态模拟，其中，Modified Gompertz方程的模拟效果更优。

| Abstract: | In order to achieve the resources utilization of rice straw and cattle manure， the effect of 3 kinds of pretreatment agents （H2O2， H2SO4， NaOH）， different concentrations of pretreatment agents （2%， 4%， 6%） and the raw material ratios of cattle manure and rice straw （1∶1， 2∶1， 4∶1） on anaerobic fermentation of mixed cattle manure and rice straw were evaluated by batch tests. The results showed that H2O2 was the optimum pretreatment agent of rice straw， the optimum concentration was 2%， and the best raw material ratio of cattle manure and rice straw was 1∶1. The average production rate of biogas was 3980 mL·g-1. At the same time， the dynamics research found that the first order kinetic model and Modified Gompertz model system both could simulate the process of biogas production in the cattle manure and rice straw mixed fermentation system. The Modified Gompertz model system was more suitable for describing the anaerobic fermentation process of producing biogas. |
