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 of toxic organic matter in sudden water pollution, phenol was selected as the representative of toxic organic compounds. By simulating the sudden phenol pollution, the emergency treatment of phenol pollution by ozone-biological activated carbon (O3-BAC) Effect, and analyzed the impact of actual environmental factors such as empty bed contact time (EBCT) and p H value on the emergency response capacity. The results showed that in the emergency treatment of sudden phenol pollution, 0.6 mg / L of ozone could make the initial phenol concentration 5 times of the influent concentration up to the standard concentration of drinking water below 0.002 mg / L and 15.3 min Of the empty bed contact time is to determine whether the critical point of the emergency process of the demarcation point, in order to obtain better emergency response, may be appropriate to increase the value of p H influent.
