厌氧活性污泥与几株产氢细菌的产氢能力及协同作用研究

THE BIO PRODUCING HYDROGEN ABILITY AND COORDINATION OF ANAEROBIC ACTIVE SLUDGE AND HYDROGENOGENIC BACTERIA

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产氢能力进行了研究．在厌氧发酵污泥中分离产氢纯菌，根据对厌氧发酵污泥与纯菌的产氢能力及协同作用的研究，表明菌种间协同作用导致了污泥的产氢能力较纯菌高，以白糖为供氢体，最大产氢能力达７６４ｍＬ／（ｇ．ｈ）．提出：在实际应用中，应充分利用菌种间协同作用，使厌氧产氢生态系统稳定，产氢量大．

Based on the anaerobic treatment of high concentration wastewater,batch anaerobic culture was employed to study the hydrogenogenic bacteria.The pure hydrogen producing bacteria were selected from anaerobic fermentation sludge.It was found that the bio producing hydrogen ability of mixed bacterium was higher than that of pure bacteria because of the coordination among bacterium.By using refined sugar as substrate,the largest capacity H 2 production was 76 4mL/(g·h).The authors propose that in the practical operation the coordination among bacterium should be fully utilized to stabilize the ecological system so that the value of bio producing hydrogen would be increased.
