一、概述Overview

反渗透技术是六十年代初问世的一种先进的膜分离技术。这种技术是使欲分离溶液的某些成分（如海水中的水）在压力的作用下，透过一种具有选择透过性的半透膜——反渗透膜，在膜的低压侧和在常温下收集透过物，而在膜的高压侧为被阻留的其他成分的浓溶液。它是一种节能、高效、无污染和实用性强的高新技术。

Reverse osmosis technology is a advanced membrane separation technology coming out at the beginning of sixties. The technology is to make some composition (as the water in the sea water) of the solution wished to separate to be affected under the pressure, to penetrate the reverse osmosis membrane—a half mirror having selection penetration, in the low pressure side of the membrane and normal temperature to collect penetrator, and in the high pressure side of the membrane is the dense solution of blocked other composition. It is a high and new technology of energy saving, high effect, no pollution and strong practicality.

水通过一种半透膜进入一种溶液或从一种稀溶液向一种比较浓的溶液的自然流动称作“渗透”，如图1（A）所示。这种对水或溶质具有选择透过性的膜谓之半透膜。但是，在浓溶液一边加上适当的压力则可使渗透停止，当稀溶液向浓溶液的渗透停止时的压力称为溶液的“渗透压”， 如图1（B）所示。反渗透则是在浓溶液一边加上比自然渗透压更高的压力，扭转自然渗透的方向，把浓溶液中的水压到半透膜的另一边，这和自然界的正常渗透过程相反，因此称为“反渗透” ， 如图1（C）所示。这种特制的半透膜称为反渗透膜。

The water’s natural flow through a half mirror enters a solution or from a dilute solution to a dense solution is called penetration.(as picture 1 “A” )the membrane having selection penetration for water and dissolved matter is called half mirror. But, put in suitable pressure on dense solution side that may stop the penetration, and the pressure during the penetration from dilute solution to dense solution stop is called solution penetration pressure. (as picture 1 “B” ) Reverse osmosis is that on dense solution side is added pressure higher than natural penetration pressure, to turn round the direction of natural penetration, let the water pressure is dense solution to affect other side of the half mirror, it is reverse to the normal penetration process in the nature,

so is called reverse osmosis. This is special half mirror is called reverse osmosis membrane. (as picture 1 “C” )

这一技术的发展起源于海水或苦咸水的淡化，因此，通常也称为淡化技术。

The development of this technology originates from the desalination of the high brackish and seawater, so normally is called desalination technology.

海水淡化是利用反渗透原理将淡水从海水中分离出来，由于反渗透膜是一种半透性隔膜，能使水分子顺利通过而阻止盐分子通过的薄膜。假如有足够的压力作用在渗透膜一侧的海水上，当加压超过海水的渗透压力时，水分子从海水侧反向通过隔膜进入淡水侧，而盐分子被隔膜所阻挡,如图2a。当然由于浓度差的关系，仍有极少一部分盐分子会渗透过去，从而影响淡水水质。由于反渗透膜透水量与驱动压力成正比，因此设计反渗透海水淡化的压力就非常重要，除了克服海水渗透压外，还需考虑流量、给水浓度变化、产水量、水质等因素，通常反渗透海水淡化装置的操作压力为3.5～6.7MPa左右，系统示意图如图2b。当高压泵达到足够的作用压力时，将有一部分淡水透过反渗透膜，剩余的部分仍处于高压的浓缩水将通过一个减压针形阀而被排出装置外。

The principle of reverse osmosis desalination is the use of fresh water from sea water to separate, as

the reverse osmosis membrane is a semi-permeable membrane and enable the smooth passage of water molecules and prevent the salt molecules to pass through the film. If there is sufficient pressure in the permeable membrane on the side of the sea, when the pressure over the infiltration of sea water pressure, water
