Development of high efficiency biogas production system on persistent organic waste by photo catalytic treatment.

本研究旨在开发利用光催化处理持久性有机废弃物的高效产气系统。以活性污泥为模型持久性有机废弃物，在最佳光催化条件下进行处理，8小时分解率达到50%以上。此外，利用处理后的活性污泥作为发酵材料进行氢气发酵，与不进行光催化处理的情况相比，氢气的产率明显提高了17倍。将光催化技术与生物修复技术相结合，开发高效、低环境负荷的生物能源生产系统是可行的，具有较大的社会影响。

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.
