摘　　要：调查了某油田的水源水、电渗析淡水和供水站生活用水中的铁细菌和硫细菌。采用滤膜集菌增菌培养方法。结果表明这3种水中硫细菌的含量随水中溶解氧量的增加而减少;铁细菌的含量则相反,随水中溶解氧的增加而增多。说明生物性厌氧腐蚀以硫细菌为主,好氧腐蚀则以铁细菌为主。分离出10种铁细菌和6种硫细菌,表明铁细菌和硫细菌是导致生活饮用水产生臭气和管道严重锈蚀、堵塞与穿孔的重要原因之一。The iron bacteria and sulphur bacteria were investigated in drinking water of certain oil field.Ten species of iron bacteria and 6 species of sulphur bacteria were isolated from the water.The result indicated that these bacteria were one of the important causes to bring about smelly and piping corrosion in water supply system of this region.
