This research is aimed at development of high efficiency biogas production system on persistent organic waste by photocatalytic treatment.The activated sludge as the model persistent organic waste was treated under the optimum photocatalatic conditions, very outstanding decomposition rate which more than 50% was obtained in 8 hours. Furthermore, as a result of performing hydrogen fermentation by using the processed activated sludge as fermentation materials, compared with the case which does not carry out photocatalytic treatment, it became clear that the rate of output of hydrogen increased 17 times.Combining the treatment of persistent organic waste by photocatalytic technology and bioremediation, a synergistic effect on development of high efficiency and low environmental load bioenergy production system could be feasible and demonstrating a large social impact.

本研究旨在开发高效光催化降解难降解有机废弃物的沼气生产系统，以活性污泥为模型，在最佳光催化条件下处理难降解有机废弃物，8h内降解率达到50%以上。此外，通过将处理后的活性污泥作为发酵原料进行氢发酵，与不进行光催化处理的情况相比，氢的输出率提高了17倍。将光催化技术和生物修复技术结合起来处理持久性有机废物，开发高效率和低环境负荷的生物能源生产系统的协同效应是可行的，并显示出巨大的社会影响。
