本文综述了关于二氧化氯(Cl O2)在饮用水处理中的应用,最先建立在欧洲国家长期稳定的试验基础之上。饮水供应主要来源地表水及其中有关微生物污染可能导致的疾病(如霍乱,伤寒,痢疾),不仅在发展中国家,而且在完全工业化的国家如美国,也是一个大问题。在饮用水处理中,二氧化氯已成功使用多年。这是一种强氧化剂和强活性消毒剂:这些特点使它非常适用于无论是在预氧化,还是在最后阶段进行消毒的常规饮用水处理。在预氧化阶段,它能够除铁除锰,同时,减少了不良气味和和恶臭的问题,也控制了系统中藻类的生长。在最后的消毒阶段低剂量的二氧化氯,短时间接触,才能保证不断贡献给社会的可靠控制的微生物供水质量。二氧化氯不产生卤化副产物及其他含氯化合物。 This article summarizes the application of chlorine dioxide (Cl O2) in drinking water treatment, first established on the basis of long-term, stable tests in European countries. Surface water, the main source of drinking water supply, and the diseases (such as cholera, typhoid and dysentery) that may result from microbial contamination, are also a big issue not only in developing countries but also in fully industrialized countries such as the United States. Chlorine dioxide has been used successfully for many years in drinking water treatment. This is a strong oxidizing agent and a strong active disinfectant: these features make it ideal for routine drinking water treatment, either in the pre-oxidation or in the final stages of disinfection. In the pre-oxidation stage, it is capable of removing iron and manganese and, at the same time, reduces the problem of bad odors and malodors and also controls the growth of algae in the system. In the final stage of disinfection low-dose chlorine dioxide, short-term exposure, in order to ensure continuous contribution to society’s reliable control of microbial water quality. Chlorine dioxide does not produce halogenated by-products and other chlorine-containing compounds.
