摘　　要：考虑到突发性水污染中有毒有机物的高频现率,选用苯酚为有毒有机物代表,通过模拟突发苯酚污染的情况,研究了臭氧-生物活性炭(O3-BAC)工艺对苯酚污染的应急处理效果,并且分析了工程中实际环境因素如空床接触时间(EBCT)、p H值对该应急能力的影响。研究表明,在突发性苯酚污染的应急处理中,0.6 mg/L的臭氧可将初始苯酚浓度5倍于达标浓度的进水处理至饮用水达标浓度,即低于0.002 mg/L,15.3 min的空床接触时间是判定其是否为该应急过程的关键因素的分界点,为了取得较好的应急效果,可适当提高进水p H值。Considering the high frequency rate of toxic organic compounds in water pollution emergency,phenol was selected as the toxic organic compound. The emergency handling ability of O3-BAC process for phenol was studied by simulating the phenol pollution,and the effects of actual environmental factors in engineering,such as EBCT and p H value were discussed. It was found that 5 times phenol initial concentration can be treated to meet the drinking water sanitary standard by O3-BAC process with 0. 6 mg / L O3 in response to the phenol pollution. 15. 3 min of EBCT is the demarcation point to judge whether it is the key factor of this process. In addition,improving the initial p H value appropriately was needed.
