摘要
依据臭氧高级氧化的机理，在实验室反应器中通过实验考察在臭氧氧化处理酸性嫩黄染料废水过程中，控制不同的O3投加量、废水的初始pH值、H2O2与O3摩尔比对酸性嫩黄染料废水的色度和COD去除率的影响。结果显示：O3高级氧化能够有效降解酸性嫩黄染料废水，体系中投加H2O2可以提高降解速率，缩短处理时间，降低O3耗量。在pH=7的条件下，单一臭氧氧化30min时，废水的色度和COD去除率分别为100％和57．1％；而提高废水的pH值有助于提高COD去除率。O3／H2O2氧化工艺，适宜的H2O2与O3摩尔比为0．6，氧化处理30min废水的COD去除率可达73．3％。
The advanced oxidation process of ozonization technique was used in treatment of the acid flavine G dye wastewater. Based on the decolorization efficiency of acid flavine G in dye wastewater, operation parameters such as dosage of O3 , initial pH of the wastewater and molar ratio of H2O2 to O3 were optimized . The results show that the advanced oxidation technique of ozonization has good effect on removal of acid flavine G, addition of H2O2 can improve degradation rate, shorten treatment time and decrease O3 consumption , when pH is 7, color decay and removal rate of COD can reach 100% and 57.1% respectively after 30 min single ozonization ,The removal rate of COD can increase along with increasing initial pH of wastewater. In the O3/H2O2 oxidation process , the suitable molar ratio of H2O2 to O3 is 0.6 ,the removal rate of COD can reach 73.3% after 30 min treatment.
