| 摘 要： | 制备并考察3种功能材料（Fe2O3、Silicalite-1和Fe2O3@Silicalite-1）的3种投加量（50、100和150 mg）对有机垃圾（鸡粪）的厌氧发酵产气影响。结果表明：各功能材料组的日沼气产量和甲烷含量相比于空白组均得到有效提高,其中Fe2O3组分别提高31.07%和10.34%;Silicalite-1组分别提高23.98%和12.07%;Fe2O3@Silicalite-1组的产气效果最佳,其最高累计产气量和甲烷含量分别提高41.39%和17.24%。由此可见,将纳米Fe2O3分散负载在多孔材料（Silicalite-1）上可作为一种有效的厌氧发酵催化剂,该材料可避免传统方法中纳米颗粒的团聚造成的自身性能失活,从而通过厌氧发酵技术耦合复合材料实现有机垃圾处理工艺的能源效益和环境效益。

| Abstract: | Three synthesized functional materials, such as Fe2O3, Silicalite-1 and Fe2O3@Silicalite-1 are investigated for subsequent promotional effects upon gas generation by utilizing organic waste （chicken manure） in anaerobic fermentation for the first time. The results exhibited that the daily biogas yield and methane contents are effectively improved by using functional materials compared with the blank groups. Among them, the Fe2O3@Silicalite-1 demonstrated the best performance in terms of the maximum cumulative gas yield and methane contents are increased by 41.39% and 17.24% compared to date of blank group, respectively. Fe2O3 group increases by 31.07% and 10.34%, and Silicalite-1 increases by 23.98% and 12.07% when compared with the date of blank group, respectively. As opposed to agglomeration of nanoparticles in traditional methods, nanostructured Fe2O3 dispersed on the surface of porous material Silicate-1 could be employed as an effective anaerobic fermentation catalyst against deactivation caused by agglomeration and hence maintains superior performance. Therefore, the energy and environmental benefits of organic waste treatment process could be accomplished by smart tailoring of composite materials with anaerobic fermentation technology. |
