摘要
臭氧氧化法在废水处理中有广泛的应用,鉴于酚类化合物在实验室废水中存在的普遍性及其对环境污染的严重性,选用了苯酚作为模型污染物,考察了臭氧氧化法的处理效果,研究了废水初始pH值和气体流量对苯酚的降解效率和臭氧利用率的影响规律。实验结果表明,废水初始pH值对臭氧氧化去除废水中苯酚和臭氧利用率的影响均很大,综合考虑各方面因素,确定出臭氧氧化处理实验室苯酚废水的最佳pH值为10．3,最佳气体流量为1．6L／MIn。为臭氧处理实验室废水打下基础。
Oaonization is widely used in wastewater treatment. Phenol was chosen as a model pollutant to determine the oxidation efficiency of ozone, whereas it is ubiquitous in lab and serious pollution to environment. The influence of original ph value and the gas flux on both the efficiency of phenol removal and the efficiency of ozone consumption was studied in this thesis. The results showed that original pH of the wastewater had a great influence on both the efficiency of phenol removal and the efficiency of ozone consumption, the initial concentration of phenol was 10 mg/L and the initial pH value was 10.3. It grounded for dealing laboratory waste water with ozone .
