针对沈阳某药厂维生素C生产工艺中凝结水产量大、处理成本高和杂质复杂等问题,提出了采用反渗透技术对工艺凝结水进行处理.通过建立中试规模膜装置,在间歇试验和连续试验的基础上,分析了膜通量、压力、运行时间、电导率、总有机碳(TOC)等指标关系,研究了运行临界通量、清洗方式等工艺条件.反渗透系统处理效果明显,脱盐率和TOC去除率分别维持在99.9％和99％以上,该工艺切实可行.%Aiming at the problems in vitamin C production process in some pharmacy plant in Shenyang, such as large condensed water quantity, high treatment cost, and complicated impurities, the reverse osmosis process was suggested to treat the production condensed water in this paper. Based on the bench experiments and continuous experiments, this paper analyzed the relationship between the indexes of membrane flux, pressure, operation time, electrical conductivity, total organic carbon (TOC) through the pilot scale membrane facility, meanwhile, some process parameters, including the critical operation flux and cleaning method, were also studied. The reverse osmosis showed good performance in study. The desalination rate and TOC removal rate were above 9 9.9% and 99 % , respectively, which indicated that this process was applicable.
