摘　　要：结合上海市金海水厂80万m^(3)/d臭氧—生物活性炭系统的调试案例,研究不同洗炭模式、累计过滤时间、活性炭浸泡时间对不合格水水质的影响。结果显示,水质不同的不合格水应选择不同的排放途径。延长单次连续过滤和前期活性炭泡炭时间,有利于尽快降低出水pH和浑浊度。单侧滤池后期大水量同时过滤对出水pH下降作用更为明显,单侧过滤水质达标后单组滤池过滤出水水质稳定。并网后深度处理系统运行稳定,出水水质符合《生活饮用水卫生标准》(GB 5749-2006)。Based on the test data of 800 000 m^(3)/d O_(3)-BAC system of Jinhai water treatment plant in Shanghai, the effects of different carbon washing modes, cumulative filtration time and carbon soaking process on the effluent quality were introduced. It is considered that unqualified water with different water quality should be discharged in different ways. Prolonging single continuous filtration and carbon soaking time can reduce the pH and turbidity of effluent. Filtration with large amount of one side later has obvious effect on the decline of pH of effluent. After the water quality of one-side filtration reached the standard, the water quality of filtration of one filter is stable. O_(3)-BAC system operates stably after the effluent is supplied to the municipal pipe network. The water quality of effluent meets the Standards for drinking water quality(GB 5749-2006).
