| 中文摘要 |
| 以长三角地区J市典型有机微污染水源P水厂为研究对象，考察了臭氧-生物活性炭深度处理工艺对微污染水源水中有机物的去除效果.结果表明，臭氧-生物活性炭深度处理使高锰酸盐指数、总有机碳（TOC）和UV254的平均去除率分别提升19.2%、10.4%和23.0%.水厂原水中检出8种多环芳烃（polycyclic aromatic hydrocarbon，PAHs）、16种有机氯农药（organochlorine pesticides，OCPs）、5种卤乙酸（haloacetic acids，HAAs），其总浓度分别为53.9~100.0、6.5~41.8、2.5×103~1.1×104 ng·L-1，臭氧-生物活性炭深度处理对多环芳烃和有机氯农药的平均去除率分别为32.5%和25.9%，比常规处理工艺出水的水质有显著提升.卤乙酸的去除率为33.8%~87.0%，主要通过常规处理工艺去除；臭氧-生物活性炭深度处理对氯代乙酸略有去除，溴代乙酸有少量生成. |
| 英文摘要 |
| Ozone-biological activated carbon (O3-BAC) was studied for the advanced removal of organics from micro-polluted source water in the water supply plant P located in J City in the Yangtze Delta Region. The results show that 19.2% of the permanganate index, 10.4% of total organic carbon, and 23.0% of UV254 were removed by the advanced treatment of O3-BAC. Eight types of polycyclic aromatic hydrocarbon (PAH), 16 types of organochlorinated pesticides (OCPs), and five types of haloacetic acids (HAAs) were detected in the source water. The total concentrations were 53.9-100.0, 6.5-41.8, and 2.5×103-1.1×104 ng·L-1, respectively. The advanced O3-BAC treatment removed 32.5% of PAHs and 25.9% of OCPs, greatly improving the effluent of the conventional water supply process. However, HAAs were mainly removed with the conventional process, with a removal rate of 33.8%-87.0%. After the advanced treatment with O3-BAC, the amount of chloroacetic acid slightly decreased, while the concentration of bromoacetic acid slightly increased. |
