对福建省闽东某水电站水库的水体及地下输水管道中的微生物生态和理化因子的调查分析结果表明，造成该水库电站输水管道连年阻塞的主要原因可能是由于铁细菌生长繁殖所致。该水库中的铁细菌主要为鞘细菌。水体温度及总铁含量对鞘细菌数量的消长具有显著影响。该水库中存在的鞘细菌最适生长条件为Ｔ２１～２５℃，ｐＨ６．１６～６．８７，Ｆｅ＞０．４３ｍｇ／Ｌ。该菌可在水深０．５～４０ｍ范围内生存。自然气候对Ｔ、总铁和悬浮物３项水体理化因子有影响，而ｐＨ、ＤＯ和ＣＯＤ则受微生物生命活动的影响。夏季为鞘细菌繁殖高峰期。建议电站地下输水管道的疏通工作以安排在９月份之后较妥
The investigation and analysis of the microbial ecology and physical and chemical factors in water bodies and underground water pipelines of a certain hydropower station reservoir in Fujian province shows that the main reason causing the blockage of water pipelines in hydropower stations in reservoirs may be due to the growth and propagation of iron bacteria. The iron bacteria in this reservoir are mainly sheath bacteria. Water temperature and total iron content have a significant impact on the growth and decline of the number of sheath bacteria. The optimal growth conditions of sheath bacteria in this reservoir were T21 ~ 25 ℃, pH6.16 ~ 6.87, Fe> 0.43mg / L. The bacteria can survive in the depth of 0.5 ~ 40m. The natural climate affects the physical and chemical factors of three water bodies, T, total iron and suspended matter, while the pH, DO and COD are affected by microbial life activities. Summer peak of sheath bacteria propagation. It is suggested that the smoothing of the underground water pipelines of the power station should be arranged after September
