| 摘 要： | 就给水深度处理中臭氧副产物的产生及其化学过程、控制臭氧副产物生成的技术措施等问题进行了探讨。采用臭氧深度处理时,会产生以甲醛为代表的有机副产物,以溴酸根为代表的无机副产物。副产物的形成与溴离子浓度、水中有机物种类和浓度、pH值、臭氧投加量、温度和碱度等因素有关。在应用臭氧进行深度处理时,应根据不同条件,采取适宜的措施,以减少臭氧副产物的生成。

| Abstract: | The generation and chemical process of ozonation by-products in drinking water advanced treatment were studied. The technical measures to control the generation of ozonation by-products were discussed. It was shown that there would be inorganic by-products (formaldehyde) and organic by-products (bromate) when using ozone. The formation of ozonation by-products was connected with the concentration of bromine ions, the kinds and concentrations of the organics in the water, pH value, the dosage of ozone, temperature, and alkalinity. When using ozone in drinking water advanced treatment, the formation of ozonation by-products should be reduced by suitable measures on the basis of different conditions. |
