| 摘要: |
| 为控制臭氧氧化含溴离子水源水时溴酸盐的产生,对影响溴酸盐生成的各因素做了系统研究.开展系列小试试验和中试试验,结果表明:溴酸盐的生成大部分发生在臭氧氧化的前10 min,当pH值大于8时,溴酸盐的生成量会显著增加,当pH值小于7时,溴酸盐的生成量小于10μg/L,氨氮和有机物的存在会抑制溴酸盐的生成.当有机物的质量浓度大于40 mg/L时,溴酸盐的产生量可以降低到10μg/L以下. |

| Abstract: |
| To control the formation of bromate in the treatment of drinking water with bromide by ozone,the influencing factors on bromate formation were studied in detail.Results of pilot test and pilot scale test show that,most of bromate are generated in the first 10 minutes of ozonation,;and when pH>8,the bromate formation is increased evidently;when pH<7,the bromate formation is limited under 10 μg/L.The existence of and NOM could inhibit the generation of bromate.When the concentration of NOM gets to 40 mg/L,the amount of bromate will be under 10 μg/L. |
