  • 摘要: 针对城市污水再生处理工艺中卤乙酸类（HAAs）消毒副产物和卤乙酸生成潜能（HAAFP），结合三维荧光光谱，分析HAAs及其前体物的变化规律。结果表明，二级出水经2次加氯过程后，再生出水中的总卤乙酸浓度增加了90%，其中溴代乙酸的增幅最大，占增加量的82%。卤乙酸生成潜能较大的为氯代乙酸类物质，说明水中存在大量的氯代乙酸前体物。从工艺过程来看，总卤乙酸生成潜能与总有机物荧光强度分别下降了32%和28%，表明该再生处理工艺对HAAs前体物有一定的去除作用。
    Abstract: In municipal wastewater reclaimation process, the variation of HAAs and HAAFP was investigated, and the concentration of HAAs precursors was analyzed with 3DEEM. The results showed that the concentration of total HAAs increased by 90% after twice chlorination, while the biggest increasing was bromated HAAs, accounting for 82%. Chlorinated HAAFP was the largest, indicating that there were a lot of chlorinated HAAs precursors. From the process, the total HAAFP and organic matter fluorescence intensity decreased by 32% and 28%, respectively, indicating that the reclaimed treatment had a certain effect on HAAs precursors removal.
