| 摘 要： | 通过对臭氧-活性炭工艺和活性炭吸附等温线的研究,探讨了臭氧-活性炭工艺去除饮用水中微量典型内分泌干扰物的可行性.壬基酚(NP)、辛基酚(OP)和双酚A(BPA)被选作目标物质.研究发现臭氧氧化能去除30%以上的NP、OP和BPA;活性炭对NP、OP和BPA也有良好的去除效果,在空床停留时间4～12 min条件下能完全去除水中未被臭氧氧化的NP、OP和BPA;吸附等温线的数据可以用Freundlich公式拟合,并用来估算活性炭的饱和时间.试验证明臭氧-活性炭工艺是去除饮用水中微量典型内分泌干扰物的有效方法.

| Abstract: | This study investigated the feasibility of using ozone-GAC process to remove typical endocrine disrupting chemicals from drinking water through a batch-scale study and adsorption isotherms.Nonylphenol (NP), Otylphenol (OP) and Bisphenol A (BPA) were selected as the representative of endocrine disrupting chemicals.Results indicated that ozonation remove more than 30% of NP, OP and BPA, GAC absorbed all the NP, OP and BPA that had not been oxidized by ozone at the condition of the empty bed contact time from 4 to 12 minutes.The isotherms for GAC were successful correlated by Freundlich equation and the data was used to estimate GAC service time.The results indicated that ozone-GAC process is a feasible way to remove NP, OP and BPA from drinking water. |
