二氧化氯消毒剂在饮用水处理中的应用

近年来,饮用水源污染日趋严重,传统消毒剂Cl2将与水中的有机物合成大量的致癌或致诱变的副产物.ClO2作为氯系消毒剂的最佳替代品,它高效广谱杀菌、作用持久、安全可靠,在饮用水消毒方面表现出巨大的发展潜力,目前已经在美国等一些发达国家得到了大力推广.但在我国广泛应用还存在着发生器运行不稳定、设备材质耐腐蚀强度不足以及消毒成本较高等问题.

The Application of ClO2 as a Disinfectant in Drinking Water Disposal

In recent years, drinking water has been increasingly contaminated. Traditional disinfectant chlorine combines with organic matter in water to form a large quantity of by-products, some of which are known causing cancer or aberrance. Chlorine dioxide is believed to be a best substitute for chlorine, which is effective in broad-spectrum sterilization, capable of long-term disinfection and safe to use. For its powerful potential in disinfecting water, it has found wide applications in the United States and other developed countries. In China, however, equipment of chlorine dioxide is flawed with operational instability, poor corrosion resistance and high cost in disinfection.
