水垢防治技术研究进展

Research progress on the prevention and control of scale

简要介绍了水系统的成垢机理及几种典型的化学、物理防垢方法,总结了各防垢方法的发展情况与存在问题:化学法简单易行、稳定高效,但对环境易造成危害,物理法控制简便、经济环保,但效果不稳定、原理复杂。指出开发环境友好型阻垢剂及高效的物理防治方法将是水垢防治的发展方向。

Scale forming mechanism of water systems and several typical chemical and physical scale-controlling methods are discussed briefly. The development state and existing problems of various prevention and control methods are summarized as follows ： chemical methods are simple, stable and efficient, but apt to cause hazards to the environment;physical methods are simple and convenient in control, economic and environmental friendly, but unstable in effect and complex in principle. It is pointed out that the development of environmental friendly scale inhibition and highly efficient physical scale-controlling methods are the developing direction of scale-controlling.
