摘　　要：对燃煤耦合污泥发电系统冷凝液进行了臭氧催化氧化实验研究,分别从催化剂选型、催化剂投加量、体系pH、臭氧投加量及接触时间五个因素入手探究其对难降解有机物去除效果的影响,进一步利用核磁共振技术及质谱技术对体系内蒽醌和萘酚的降解过程进行了监测。实验表明,当选用Fe/γ-Al_(2)O_(3)为催化剂且投加量为6 g/L,体系pH为9.2,臭氧投加量为120 mg/L,接触时间为120 min时,臭氧催化氧化对剩余难降解有机物的去除效果最佳,去除率可达83.2%,核磁共振和质谱监测结果也显示芳香类有机物随接触时间延长而迅速发生降解。The ozone catalytic oxidation experiment was carried out on the condensate of coal-fired coupled sludge power generation system,and its effect on the removal of refractory organic matter was investigated from five factors:catalyst selection,catalyst dosage,system of pH,ozone dosage and contact time.Furthermore,the degradation process of anthraquinone and naphthol in the system was traced by nuclear magnetic resonance and mass spectrometry.The experiments showed that:when Fe/γ-Al_(2)O_(3)is selected as the catalyst and the dosage is 6 g/L,the pH of the system is 9.2,the dosage of ozone is 120 mg/L,and the contact time is 120 min,the removal effect of ozone catalytic oxidation on the remaining refractory organic matter is the best,and the removal rate was up to 83.2%.The monitoring results of nuclear magnetic resonance and mass spectrometry also showed that the aromatic organics degraded rapidly with the prolongation of contact time.
