摘要:
使用UV/H2O2工艺深度处理污水厂尾水,评估对水中有色可溶性有机物(CDOM)的去除效果。基于三维荧光光谱组合平行因子分析,提取出3个有效荧光组分,分别代表C1(色氨酸类蛋白)、C2(类腐殖酸)和C3(酪氨酸类蛋白)。UV/H2O2工艺能有效去除CDOM荧光组分,使用响应面分析对反应条件进行优化,优化后最佳反应条件为:H2O2投加量1.2 m g/L、紫外光强7.1 mW/cm2、反应时间43 min,荧光组分C1预测和实际去除率分别为94.2%和91.8%,说明响应面能够有效描述UV/H2O2工艺降解反应过程,优化降解反应条件,为UV/H2O2氧化工艺工程应用提供技术参考。
Abstract:
UV/H2O2 process was used to treat tail water from wastewater treatment plant. The removal efficiency of colored dissolved organic matter(CDOM)was evaluated. Three dimensional fluorescence combination of parallel factors analysis were to successfully extract three effective fluorescent, including C1(Tryptophan class protein)、C2(Humic acid)and C3(Tyrosine protein).The results show that UV/H2O2 process can effectively remove the fluorescence components. RSM was also used to optimize reaction conditions. Under optimization conditions of H2O2 dosage of 1.2 mg/L、ultraviolet light intensity of 7.1 mW/cm2, reaction time of 43 min, the predict and real removal rate of C1 were 94.2% and 91.8%, respectively. Response surface model can effectively reflect and predict the reaction results and optimize reaction conditions. The research provides reference for UV/H2O2 oxidation process engineering application.
