离子交换净水法是离子交换剂在工业上最早的一种应用,现在仍然是离子交换树脂的最重要的应用之一。依据对水净化深度的不同要求,发展了软化、部分脱盐、完全脱盐等多种离子交换过程。所有工业离子交换过程的水源,都必须予先处理成无悬浮物和胶状物的清水,然后进行离子交换。下面我们的讨论,都从使用这种予处理后的清水出发。 Ion exchange water purification method is the first ion exchanger industry in the application, is still one of the most important ion exchange resin applications. According to the different requirements of water purification depth, the development of softening, partial desalination, complete desalination and other ion exchange process. All industrial sources of water for ion exchange must be pre-treated with water free of suspended solids and jelly and then ion-exchanged. Our discussion below starts with the use of this pre-treated water.
