| 摘 要： | 采用UV-Fenton技术光催化氧化高浓度木糖生产废水,确定最佳操作条件为:pH=2.5,H2O2=46.62g/L,H2O2/Fe2+摩尔配比为50∶1,光照反应60min。此条件下废水COD去除率最高可达91.2%。经正交试验确定影响处理效果各因素的重要性顺序为:pH>H2O2浓度>光照反应时间>H2O2/Fe2+摩尔配比。UV的加入与单独的Fenton体系存在正相关的协同作用。经UV-Fenton处理后的木糖废水,可生化性大大改善,B/C指标从0.21升高到0.49。

| Abstract: | UV-Fenton catalysis oxidization process was used to treat high concentration xylose production wastewater,with optimal operation conditions as pH 2.5,H2O2 46.62g/L,mole ratio of H2O2/Fe2+ 50∶1 and illumination reaction time 60min,under which COD removal efficiency of wastewater can reach 91.2%.The addition of UV has positive correlation synergies with independent Fenton system.Biochemical conversion property of xylose wastewater was greatly improved after UV-Fenton treatment and B/C index increased to 0.49 from 0.21. |
