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. 1×104ng·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.Ozone-biological activated carbon （03-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 polyeyelie 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 ×10^3- 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 chloroacetie acid slightly decreased, while the concentration of hromoaeetic acid slightly increased.
