摘要
反渗透水处理技术是当今先进、节能、环保的分离技术,其原理是在高于溶液渗透压的压力作用下,借助于只允许水透过而不允许其他物质透过的半透膜的选择截留作用将溶液中的溶质与溶剂分离。利用反渗透膜的分离特性,可以有效地去除水中的溶解盐、胶体、有机物、细菌、微生物等杂质,具有能耗低、无污染、工艺先进、操作维护简便等优点。通过对引入反渗透水处理技术在中国华电集团富拉尔基发电总厂锅炉补给水处理中的应用与传统的离子交换除盐水处理系统的经济性的对比,阐述了反渗透水处理技术的原理及应用优势。
The reverse osmosis water treatment technology is the most advanced,energy-saving and environment protecting separation technology today. The principle is that under the pressure higher than the solution infiltrating pressure,the semipermeable membrane will allow the water to pass and prevent other materials to pass,and by using this selection feature of semipermeable membrane,the solute and solvent can be separated. Utilizing the filtering features of semipermeable membrane,the dissolved salt,colloid,organic matter,germ and some other impurity can be efficiently removed from water. This technology has advantages of lower energy consumption,pollution free,advantageous technology,simple for operation and maintenance and so on. The economical efficiency of the reverse osmosis water treatment technology applied in boiler make up water treatment system of Huadian Fularji General Power Plant of China Huadian Corporation and that of the traditional ion exchange desalination water treatment system were compared,the principle and application advantage of the reverse osmosis water treatment technology were expounded.
