摘要
采用内循环管式光催化反应器,考察不同的温度、有机物底物浓度、光照强度、曝气强度等因素对水中喹啉的降解效果影响,在此基础上进行降解动力学研究。实验结果表明:温度、喹啉初始浓度、光照强度、曝气强度等因素与喹啉的催化降解呈现良好的相关关系,喹啉的表观吸附平衡常数为0.0244 L/mg,溶解氧表观吸附平衡常数为2.11,反应活化能为16.734 kJ/mol,光照强度修正指数为0.525。
Foam-nickel photocatalytic reactor was applied to investigate me eilect of temperature intensity,organic substrate concentration, irradiation intensity and aeration intensity on the degradation rate of quinoline,degradation kinetics was also investigated. Experimental results indicate that temperature, the initial concentration of quinoline, irradiation intensity, aeration intensity are the main factors associated with catalytic degradation of quinoline and show good relations. The quinoline adsorption equilibrium constants, dissolved oxy- gen adsorption equilibrium, reaction activation energy and irradiation intensity correction index were 0. 0244 L/ rag,2.11,16. 734 kJ/mol and 0. 525, respectively.
