摘要
通过对2级反渗透保安过滤器进出、水及滤芯粘泥成分的研究表明,造成2级反渗透保安过滤器滤芯频繁污堵的水垢样中主要含有滤芯截留的有机物质(乙酸类有机物/盐,还有部分由炼化膜用阻垢剂、杀菌剂引入的其它有机物质)、无机物质(Fe、Ca、Mg型硫酸盐、炼化膜用阻垢剂中磺酸钠等组分)及大量微生物粘泥(TGB、FB)。建议重新评选适用的杀菌剂,并对含乙酸脱钙废水单独预处理,在确保装置运行的同时延长滤芯使用周期,降低系统维护费用。
After studying the composition of inlet and outlet water and filter element slime of secondary reverse osmosis cartridge filter,the results showed that the scale sample which caused frequent fouling and plugging of the filter element of the secondary reverse osmosis cartridge filter mainly contained the organic matter intercepted by the filter element(acetic acid organic matter/salt,and some other organic matter introduced by scale inhibitor and bactericide for refining and chemical membrane),inorganic substances(Fe,Ca,Mg type sulfate,sodium sulfonate in scale inhibitor for refining and chemical membrane)and a large number of microbial slime(TGB,FB).It is suggested that the suitable green environment-friendly and efficient bactericides should be re-selected,and the decalcification wastewater containing acetic acid should be pretreated separately,so as to ensure the normal and stable operation of the plant,greatly prolong the service life of the filter element and reduce the maintenance cost of the system.
