工业循环水中油含量是水常规分析项目 ,其指标应控制在 2mg/L以下。油能与循环水中的悬浮物 (泥砂、铁的氧化物等 )结合 ,形成污垢 ,堵塞换热等设备的管道 ,腐蚀设备 ;油还为微生物提供营养 ,促进厌氧菌生长 ;油垢造成设备点蚀 ,甚至泄漏 ,对生产危害很大。循环水中油含量的测 Industrial circulating water, oil content is routine water analysis project, its indicators should be controlled at 2mg / L or less. Oil can be combined with suspended solids (silt, iron oxides, etc.) in the circulating water to form fouling, clogged pipes for equipment such as heat exchange, and corrosion equipment. Oil also provides nutrients to microorganisms and promotes the growth of anaerobic bacteria. Erosion, or even leakage, a great harm to production. Determination of circulating water content of oil
