| 摘要: | 进料负荷对餐厨垃圾与水稻秸秆混合厌氧发酵产氢过程有重要影响. 以进料负荷为影响因子, 设置温度均为55℃的餐厨垃圾与水稻秸秆混合厌氧发酵产氢实验, 其中进料负荷(以VS计)分别设置为(A)5kg?m-3?d-1、(B)10kg?m-3?d-1、(C)15kg?m-3?d-1, 分析厌氧产氢过程中产气量、产氢速率、pH、VFAs、氨氮、SCOD等参数的变化. 实验结果表明: B组发酵底物产气量最大, 为8664mL, 产氢速率也最大, 为748.3mL?h-1, 反应过程中pH始终维持在5.5±0.1内, 是厌氧产氢的最佳范围. 实验结束时, 各组VFAs、氨氮浓度分别为7292.46、8248.35、8558.24mg?L-1和544.48、754.31、1458.33mg?L-1. 同时各组SCOD浓度变化趋势相似. 在研究范围的最佳进料负荷下, 进行回流比分别为10%、30%、50%的实验, 结果显示30%回流比的产氢量最大, 为56039mL, 同时运行过程中系统稳定性较好. 综上所述, 进料负荷为10kg?m-3?d-1, 30%回流比的餐厨垃圾与水稻秸秆混合厌氧发酵产氢时, 微生物活性较好, 能够产生更多的氢气. 这一结果可为餐厨垃圾资源化提供参考依据. |
| Abstract: | The feed load has an important effect on hydrogen generation in the anaerobic fermentation process of kitchen waste and rice straw. In the hydrogen production experiment with feed load as influence factor and setting temperature to 55℃, and the load ( calculated as VS ) is made of (A) 5kg?m-3?d-1, (B) 10kg?m-3?d-1, and (C) 15kg?m-3?d-1. The changes are analyzed of gas production, hydrogen production rate, pH, VFAs, ammonia nitrogen, SCOD and other parameters in anaerobic fermentation of kitchen waste. The results show that group B achieved the outcome in which the largest gas production is 8664mL and hydrogen production rate is 748.3mL?h-1. The pH of reaction is always maintained at 5.5±0.1, being the best range of hydrogen production. In the final phase of the experiment, the concentrations of VFAs and ammonia nitrogen in each group are found to be 7292.46, 8248.35, 8558.24mg?L-1 and 544.48, 754.31, 1458.33mg?L-1. The SCOD trend of each group is approximately the same. Under the optimal feed load with the previous setting, by conducting the experiments with the reflux ratio of 10%, 30% and 50%, the results show that 30% reflux ratio has the largest hydrogen production being 56039mL, and the system stability is good throughout the operation. In conclusion, when the feed load is 10kg?m-3?d-1, and 30% reflux ratio of kitchen waste and rice straw are mixed up with anaerobic fermentation for hydrogen production, the microbial activity is good and can produce more hydrogen, which can provide a reference for recycling kitchen waste as a useful resource. |
