摘　　要：本文在厌氧污泥处理高浓度有机废水的基础上，为了提高厌氧产氢细菌的产氢能力，采用间歇厌氧培养实验对产氢菌群生态学进行了研究。产氢菌群生态位、生态因子和种间协同作用的研究表明，Ｏ２、ｐＨ值、ＣＯＤ浓度的变化会引起发酵类型的变化。在厌氧产氢污泥中分离纯菌，通过发酵污泥混菌与纯菌的产氢能力的比较，表明了菌群间协同作用在产氢发酵中的作用。以白糖为供氢体，混菌的最大产氢能力达８４．４ｍｌＨ２／ｇ菌体·ｈ。提出了乙醇型发酵的最优控制因素。On the basis of the anaerobic treatment of high strength wastewater,batch anaerobic culture is employed to research the hydrogenogenic bacteria.According to the research on niche,ecological factors and coordination among bacterium,it indicates that the change of O 2,pH,COD concentration may lead to the change of fermentation type.Pure hydrogen producing bacteria were isolated from anaerobic fermentation sludge.By using refined sugar as substrate,the largest H 2 production was 84.4 ml H 2/g bacteria·h.The comparison on hydrogen producing ability between sludge mixed and pure bacteria shows that coordination among bacteria plays a major role in hydrogen producing.The optimal ecological control factors of ethanol type fermentation is put forward.
