| 摘 要： | 臭氧消毒近年来为各地农村供水工程所广泛采用，但其带来的副产物溴酸盐超标问题却没有引起足够的重视。对北京若干区县的实际水样进行臭氧投加试验，考察了副产物溴酸盐的生成情况，探讨了臭氧消毒的适用性。结果表明：北京地区地下水采用臭氧消毒时溴酸盐超标的风险较高，建议在选择臭氧消毒前首先对原水进行臭氧投加试验，并考察生成溴酸盐的浓度水平；臭氧投加方式对于溴酸盐生成量的影响较大。

A Preliminary Study of the Formation of Bromate By-products During Ozone Disinfection in Rural Drinking Water Supply |
| |
| Abstract: | Ozone disinfection was widely used in many rural drinking water supply projects. However, it was needed to attract more attention that the bromate by-product formed may be over standard in the disinfection process. In this paper, ozone adding experiments towards groundwater samples of different rural drinking water projects from various towns in Beijing were developed, and the bromate formation of the water samples was observed. Results showed that risk of bromate of theses groundwater samples from Beijing exceeding the standard values was rather high after ozone disinfection. Besides, ozone dosing methods had a significant effect on formation of bromate. |
