海水淡化即利(li)用(yong)(yong)海(hai)(hai)水(shui)(shui)(shui)(shui)(shui)脱盐(yan)工艺生产淡(dan)水(shui)(shui)(shui)(shui)(shui)，反渗(shen)(shen)(shen)(shen)(shen)透(tou)(tou)(tou)法是目前海(hai)(hai)水(shui)(shui)(shui)(shui)(shui)淡(dan)化(hua)主(zhu)要处理技术之(zhi)一(yi)(yi)(yi)，反渗(shen)(shen)(shen)(shen)(shen)透(tou)(tou)(tou)法是利(li)用(yong)(yong)只允许(xu)溶剂(ji)透(tou)(tou)(tou)过(guo)(guo)、不允许(xu)溶质透(tou)(tou)(tou)过(guo)(guo)的(de)半透(tou)(tou)(tou)膜(mo)将海(hai)(hai)水(shui)(shui)(shui)(shui)(shui)与(yu)淡(dan)水(shui)(shui)(shui)(shui)(shui)分隔开，在通(tong)(tong)常情况下，淡(dan)水(shui)(shui)(shui)(shui)(shui)通(tong)(tong)过(guo)(guo)半透(tou)(tou)(tou)膜(mo)扩散到海(hai)(hai)水(shui)(shui)(shui)(shui)(shui)一(yi)(yi)(yi)侧，因受半透(tou)(tou)(tou)膜(mo)的(de)阻力，海(hai)(hai)水(shui)(shui)(shui)(shui)(shui)一(yi)(yi)(yi)侧的(de)液面逐渐升高，直至(zhi)升到一(yi)(yi)(yi)定的(de)高度才停止，这个(ge)过(guo)(guo)程为渗(shen)(shen)(shen)(shen)(shen)透(tou)(tou)(tou)。此时，海(hai)(hai)水(shui)(shui)(shui)(shui)(shui)一(yi)(yi)(yi)侧高出的(de)水(shui)(shui)(shui)(shui)(shui)柱静压称为渗(shen)(shen)(shen)(shen)(shen)透(tou)(tou)(tou)压。如果对海(hai)(hai)水(shui)(shui)(shui)(shui)(shui)一(yi)(yi)(yi)侧施(shi)加一(yi)(yi)(yi)个(ge)大于海(hai)(hai)水(shui)(shui)(shui)(shui)(shui)渗(shen)(shen)(shen)(shen)(shen)透(tou)(tou)(tou)压的(de)外压，那么海(hai)(hai)水(shui)(shui)(shui)(shui)(shui)中的(de)纯水(shui)(shui)(shui)(shui)(shui)将渗(shen)(shen)(shen)(shen)(shen)透(tou)(tou)(tou)到淡(dan)水(shui)(shui)(shui)(shui)(shui)中。反渗(shen)(shen)(shen)(shen)(shen)透(tou)(tou)(tou)法的(de)最(zui)大优点是节约场地和(he)能(neng)耗。反渗(shen)(shen)(shen)(shen)(shen)透(tou)(tou)(tou)法海(hai)(hai)水(shui)(shui)(shui)(shui)(shui)淡(dan)化(hua)系(xi)(xi)统(tong)(tong)(tong)主(zhu)要由超滤系(xi)(xi)统(tong)(tong)(tong)、第一(yi)(yi)(yi)级(ji)反渗(shen)(shen)(shen)(shen)(shen)透(tou)(tou)(tou)系(xi)(xi)统(tong)(tong)(tong)、第二级(ji)反渗(shen)(shen)(shen)(shen)(shen)透(tou)(tou)(tou)系(xi)(xi)统(tong)(tong)(tong)、膜(mo)清洗系(xi)(xi)统(tong)(tong)(tong)、化(hua)学品储存与(yu)加药系(xi)(xi)统(tong)(tong)(tong)组成。
