饮用水消毒方法的研究进展

Progress in Drinking Water Disinfection Methods

氯气消毒因其技术成熟,价格低廉,在管道中具有持续消毒作用而被绝大多数水厂应用。但其消毒过程中会产生三卤甲烷等致癌、致突变、致畸性的消毒副产物。新兴消毒技术一定程度减少了有害消毒副产物的生成,但其造价昂贵,氧化性差导致消毒效果不佳,不易保存,没有持续消毒效果,目前难以广泛应用。未来饮用水消毒技术的发展,应在汲取现有技术的优点基础上,探究成本低、危害小、消毒质量优良的组合消毒技术。

Chlorine disihfection because of its mature technology, low price, with continued disinfection in the pipeline and the vast majority of water is applied. But its disinfection process will produce trihalomethanes and other carcinogenic, mutagenic, teratogenic disinfection byproducts. Emerging disinfection technology to a certain extent reduces the formation of harmful disinfection by-products, but its high cost, poor oxidation resistance leading to poor sterilization effect, not easy to save, there is no continuous disinfection, it is difficult to widely used. The future development of drinking water disinfection technology should draw advantage of existing technology to explore the low cost, low hazard, excellent quality combined disinfection disinfection technology.
