Ozone-biological activated carbon (O-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 UV were removed by the advanced treatment of O-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 2.5×10-1.1×10 ng·L, respectively. The advanced O-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 O-BAC, the amount of chloroacetic acid slightly decreased, while the concentration of bromoacetic acid slightly increased.
对位于长江三角洲地区J市的P水厂中臭氧 - 生物活性炭（O - BAC）深度去除微污染水源水中有机物的情况进行了研究。结果表明，O - BAC深度处理去除了19.2%的高锰酸盐指数、10.4%的总有机碳和23.0%的紫外线吸光度值。在源水中检测到8种多环芳烃（PAH）、16种有机氯农药（OCP）和5种卤乙酸（HAA），其总浓度分别为53.9 - 100.0、6.5 - 41.8和2.5×10 - 1.1×10 ng·L。O - BAC深度处理去除了32.5%的PAH和25.9%的OCP，极大地改善了常规供水工艺的出水水质。然而，HAA主要在常规工艺中被去除，去除率为33.8% - 87.0%。经过O - BAC深度处理后，氯乙酸的量略有下降，而溴乙酸的浓度略有上升。
