Control Strategy 1: Alternative Oxidants and Disinfectants 控制策略1:替代氧化剂和消毒剂
发布日期: 1991-01-01
作者用“氧化副产物”一词代替消毒副产物,概述了问题、原因和一些可能的解决方案。本文的基础是一系列表格、图表和其他图表,比较了几种消毒剂和氧化剂,包括游离氯、氯胺、二氧化氯、臭氧、臭氧/过氧化氢、紫外线和高锰酸钾。全面比较了氧化剂及其在处理常见水质问题(硫化氢等)方面的有效性;同样,还比较了消毒剂及其处理细菌、囊肿和病毒的能力。 列出了54种消毒副产品,并用标记显示了哪种消毒剂/氧化剂导致了哪种副产品的产生。综述了氧化剂副产物的毒性。比较了氯、二氧化氯和氯胺作为残留消毒剂的价值。一张图表根据氧化、初级消毒和残余维护的有效性对许多氧化剂进行了评级和比较。作者得出的结论是,最好的策略是臭氧氧化和初级消毒,以及游离或组合氯气进行剩余维护。
The author substitutes the term "oxidation byproducts" for disinfection byproducts in this general overview of the problem, its causes, and some possible solutions. The basis of the paper is a series of tables, charts, and other graphic comparisons of several disinfectants and oxidants, including free chlorine, chloramines, chlorine dioxide, ozone, ozone/peroxide, ultraviolet light, and potassium permanganate. An overall comparison of oxidants and their effectiveness in dealing with common water quality problems (hydrogen sulfide, etc.) are given; similarly, a comparison of disinfectants and their abilities to deal with bacteria, cysts, and viruses are compared. Fifty-four disinfection byproducts are listed, with markers to show which disinfectant/oxidant leads to the creation of which byproduct. Toxicity of oxidant byproducts is summarized. Chlorine, chlorine dioxide, and chloramines are compared for their value as residual disinfectants. A chart rates and compares a number of oxidants with regard to their effectiveness in oxidation, primary disinfection, and residual maintenance. The author concludes that the best strategy is ozone for oxidation and primary disinfection and free or combined chlorine for residual maintenance.
