为了实现用可再生资源—养殖废水生物制氢的目的，在实验室规模装置上，首先通过单因素及正交实验，找到了温度30℃、pH值7.0、光照强度1600lux、污水COD浓度5687mg/L为光合细菌进行养殖废水发酵制氢的最佳条件；其次通过查阅相关文献，拜访专家，分析及比对现有的辅助加热式沼气系统，探索性研究了将生物制氢工艺与现有的养殖废水沼气发酵工艺联合起来，在养殖废水沼气装置中组合进废水制氢装置，得出了几乎不用另外投加任何形式的能量及原料即可实现氢气和甲烷同时制取这一大胆设想是可行的、科学的结论。并初步设计了氢气—甲烷联合制取系统装置模型，为缓解能源危机，充分合理地利用可再生资源，奠定了基础。

In order to produce hydrogen from poultry breeding wastewater, a device and some experiments were designed in the laboratory. First, single factor and orthogonal tests were used to determine the optimum conditions of producing hydrogen by photosynthetic bacteria. The optimum conditions were found to be temperature of 30℃, pH 7.0, illumination intensity of 1600lux and the sewage density of 5687mg/L. Then, after referring to literature, consulting with experts, and analyzing and comparing with the current auxiliary heating cluster case type biogas system, the combination of bio-hydrogen production technology and the methane production technology from the poultry breeding wastewater was explored, and the device of bio-hydrogen production from wastewater with the existing methane production was made. It is concluded that the new system can produce hydrogen and methane simultaneously almost without providing any extra energy and substrate. Finally, the preliminary model device of integrated methane and bio-hydrogen production was designed, which paved the way for alleviating the energy crisis, and fully and rationally utilizing renewable resources.
