摘　　要：根据华能上安电厂循环水水质和处理技术特点,设计了反渗透模拟装置,选用多种杀菌剂进行静态浸泡试验和动态模拟试验。在进水中含有不同杀菌剂情况下,对反渗透模拟装置的回收率及脱盐率等进行分析研究,系统地评价不同杀菌剂对反渗透膜性能的影响。研究结果表明,所研制的绿色杀菌剂对于采用反渗透脱盐技术处理循环水排污水的电厂较为适用,它不仅对循环水中的细菌有很好的杀灭作用,而且不会对反渗透膜产生影响;优氯净和1227杀菌剂均不适于此类电厂使用。Based on the circulating water quality and the treatment technology features in Huaneng Shang＇an Power Plant,a simulation facility of reverse-osmosis（RO） has been designed,the static soak test and dynamic imitation test being carried out by using many kinds of bacteriside.Under condition of different bactericides containing in the inlet water,the recovery rate and desalination rate etc.of said simulation facility of reverse-osmosis have been analysed and studied,the influence of different bactericaides upon the performance of reverse-osmosis membrane being systematically evaluated.Results of study show that the developed green bactericide is suitable to power plants using RO desalting equipment to treat the blowdown circulating water,it not only can kill the bacteria in circulating water,but also can＇t affect the RO membrane;the bactericides,such as DCCNa and benzulconium chloride can＇t be used in this kind of power plant.
