反渗透膜保养方式研究

Investigation on the maintenance of reverse osmosis membrane

反渗透水处理作为一种科技含量较高的水处理脱盐技术,在当今工业生产中应用越来越广泛。结合郑州热电厂水处理设备运行负荷变化的特点,就反渗透膜的长期保养技术及工艺进行探讨,采用药液(甲醛溶液)进行反渗透膜长期保养,一方面节约了能源,降低了生产成本,另一方面又保证了反渗透系统运行的可靠性。

Acted as one of the hightech water treatment methods, reverse osmosis has been applied in many processes of industrial production. Based on the characteristic of water treatment equipment in Zhengzhou Thermoelectric Power Plant, this paper discusses the longtime maintenance technology and technique of RO membranes. It saves energy and reduces the cost of production using chemicals to keep RO membrane clean. At the same time, it also guarantes the reliability of RO system.
