对四川什邡市某水厂臭氧-生物活性炭（O3/BAC）深度处理工艺进行分析，阐述了O3/BAC工艺的工程经验和措施，具体工艺方案为：在有空气分离制氧企业的城市，当臭氧耗量Q≤60 kgO3/h时选择外购液氧，反之可考虑现场空气分离制氧；预臭氧氧化效果与O3加注量Q的相关性大于接触时间T的影响，若原水需杀藻，T建议≥5 min；主臭氧接触池三段式最佳投加比例为4∶3∶3，控制CT值（CT≥4 min? mg/L）对杀灭“两虫”有表征意义；活性炭吸附与结构性能的关键指标建议值为：碘值≥900 mg? g-1，亚甲兰值≥150 mg? g-1，比表面积≥1000 m 2?g-1，总孔容积≥0.6 cc? g-1；炭滤池上设透光密封罩，炭层下增加500 mm砂层，并降低设计滤速对保障运行安全、降低微生物穿透滤层的风险有利。

Ozone-Biological Activated Carbon (BAC/O3 ) process design was introduced in one first bulited water treatmen plant in Shifang Shichuan China.This paper discussed the experience and measures for O 3/BAC technology project.If the thecholgy for separa-ting oxygen from air was provided in project location , when the ozone consumption Q o3≤60 kgo3/h , purchase of liquid oxygen as the raw material would be more economical , when Qo3 >60 kgo3/h, adopting the separated oxygen from air whould be better .In pre-ozona-tion reactor, O3 charging quantity Q had more effect on the ozone oxidation effect than contact time T ,but if the raw water needed to kill alga, adviced T≥5 min;In post-ozonation reactor,usually divided into three phases , the best dosing ratio was 4∶3∶3,and the CT value (CT≥4 min? mg/L) had representation meaning to kill “two bug”.The key indicators value of the Activated carbon adsorption and structure properties were introduced:iodine value was 900 mg? g-1 , and JiaLan value was 150 mg? g-1 , or specific surface area of 1000 1000 m 2? g-1 , total pore volume was 0.6 cc? g-1 , etc.; The light seal cover should be bulited above carbon filter , 500 mm sand was added under the carbon layer and design filter speed should be reduced to ensure safety operation and reduce the risk of mi -crobial penetration filter layer.
