| 摘 要： | 用臭氧对含溴化物的饮用水进行消毒时会生成溴酸盐副产物，溴酸盐被国际癌症研究机构定为2B级（具有较高的致癌可能性）潜在致癌物。臭氧氧化溴化物生成溴酸盐要经过多步反应，控制溴酸盐生成的方法有加氨、降低pH值、投加活性炭、投加高锰酸盐和增加臭氧投加点的数量等。用臭氧消毒的最终目的是杀灭致病菌，因此如何找到臭氧、致病菌、溴酸盐消毒副产物之间的最佳平衡点还有待进一步研究。

| Abstract: | Ozonation of drinking water containing bromide may lead to the formation of bromate, which is considered to be a potential 2B-level carcinogen by International Agency for Research on Cancer (IARC). Bromate is formed through multiple reactions during ozonation of drinking water containing bromide. Methods of control the formation of bromate include ammonia addition, pH decreasing, dosing activated carbon or permanganate, and increasing the number of dosing position, etc. The critical objective of ozone disinfection is inactivation of pathogenic bacteria. Therefore, further investigation to find the optimal balance among ozone, pathogenic bacteria and bromate should be conducted. |
