摘　　要：金明热电厂反渗透系统预处理在技术改造前,保安过滤器滤芯更换频繁,运行一段时间后,系统脱盐率明显降低,降至93%,膜污染严重。反渗透膜经过离线清洗,脱盐率升至95%,系统预处理改造后滤芯更换周期加长,系统长时间运行脱盐率基本保持在95%,减轻了对膜的污染,保证了系统长期稳定运行。Abstract： Before the improvement in the pretreatment of reverse osmosis system in Jinming thermo-electric plant, it needed to change precision filter element frequently, and after some time, the desalination ability of system obviously decreased to 93 % and osmosis membrane was polluted seriously. After off-line cleaning, desalination rate raised to 95 %. The replacing period of filter element is prolonged and the membrane pollution is lightened. Morever the system could function steadily for a long time.
