再生水补给河道中内分泌干扰物壬基酚变化特征分析
|
摘要
通过监测再生水补给河道中壬基酚同分异构体的含量和分布,分析壬基酚在河道中的变化过程并对其进行综合评价,为再生水补给河道的生态风险评价提供科学支撑。结果表明,再生水中NP同分异构体的含量存在差别,其中含量最大的是NP10、NP9、NP4和NP2,含量最高的NP10是含量最低的NP8的6倍左右。再生水补水河道中壬基酚同分异构体的含量波动较大,壬基酚在河道中降解现象明显,但是不存在明显的同分异构体间的转化。河道中壬基酚含量的变化与季节关联性较弱,与补水壬基酚的含量关联性较强。基于因子加权法得出的壬基酚浓度能够较客观地表征河道中壬基酚的危害性,河道断面壬基酚的综合评价结果远小于将同分异构体数值几何相加的结果,直接几何相加检测浓度难免夸大河道中壬基酚的危害。结果为再生水安全回用提供参考。
In this study, the content and distribution of nonylphenol isomers in the reclaimed water supply river were monitored, then the variations of nonylphenol in the river channel was analyzed and its comprehensive evaluation were conducted. This will provide scientific support for the ecological risk assessment of reclaimed water supply rivers. The results showed that there were differences in the content of NP isomers in reclaimed water. Of which NP10, NP9, NP4 and NP2 had the highest content, and NP10 content was about 6 times NP8,which had the lowest content. The content of nonylphenol isomers fluctuated greatly in the reclaimed water supply river, and nonylphenol presented a distinct degradation in the river channel, while no distinct conversion occurred among its isomers. The change of nonylphenol content in the river showed a weak correlation with the seasons and a strong correlation with the content of nonylphenol in the reclaimed water supply. The concentration of nonylphenol based on the factor weighting method could objectively characterize the harm of nonylphenol in the river channel. The comprehensive evaluation results of nonylphenol in the river section were much lower than directly geometric sum of its isomer values, the latter result inevitably exaggerated the hazards of nonylphenol in the river. The results could provide a reference for the safe reuse of reclaimed water.
