摘要
采用新型工艺UV/H2O2/微曝气对水中内分泌干扰物（EDCs）4-叔丁基苯酚（BP）的降解进行研究.结果表明,UV/H2O2/微曝气工艺比UV/H2O2工艺可以更为有效地去除水中BP;UV/H2O2/微曝气联用工艺降解BP受BP初始浓度值、UV光强、初始H2O2投加浓度以及溶液初始pH影响较大.随着光强的增大,BP的降解速率呈线性增长;在329-882μg/L浓度范围内,k1随着浓度的增大而逐步降低;随着初始H2O2投加浓度从1mg/L上升到20mg/L,k1几乎呈线性增长;当BP溶液pH值为3.94时,UV/H2O2/微曝气对BP的降解速率最大.
The degradation of EDC 4-tert-butylphenol （BP） in water was studied adopting a new model technique. UV/H2O2/micro-aeration could remove effectively BP in water than UV/H2O2. UV/H2O2/micro-aeration combined use technique, degrading BP was influenced more greatly by BP initial concentrations, UV light intensity, initial H202 adding concentration and initial pH of solution. The BP degradation rate appeared linear growth; in the range of 329-882μg/L; concentration k1 decreased gradually with increase of concentration; with initial adding concentration of H2O2 raised from 1mg/L to 20mg/L; k1 almost appeared linear growth; when the pH of BP solution was 3.94, the BP degradation rate by UV/H2O2/Micro-aeration was the greatest.
