| 摘 要： | 试验研究了UV/H2O2工艺处理模拟城市污水处理厂尾水中低浓度的DBP,考察了工艺参数和水质参数对DBP降解效果的影响。结果表明,单独UV光照或单独H2O2对DBP的降解效果远低于两者的协同作用。DBP的降解效率随着H2O2投加量的增加而增大,随着DBP初始质量浓度的增大而减小,且其光降解速率常数与其初始质量浓度成拟一级反应动力学关系。在DBP初始质量浓度为1～100μg.L-1,H2O2投加量为0.10 g.L-1,UV辐射强度为24.26μW.cm-2的条件下,反应进行30 min后,DBP降解率均可达到90%以上,且pH对其降解效果影响小。UV/H2O2工艺对于浊度低、成分复杂的城市污水处理厂尾水中低浓度的DBP去除率为85%,比去离子水中配制的DBP原水降解率低14%。 |

| Abstract: | UV/H2O2 process was used for advanced treatment of low concentration DBP in the tail water of municipal sewage plant,the removal of DBP and the influence factors were investigated.It was found that the decomposition efficiency of UV alone or H2O2 alone was worse than that of the synergetic.The decomposition efficiency increased with the increase of H2O2,and decreased with the initial concentration of DBP.The reaction between DBP and UV/H2O2system can be regarded as pseudo-first order kinetics.When the initial concentration of DBP was 1 to 100 μg·L-1,the concentration of H2O2 was 0.10 g·L-1,the UV radiation intensity was 24.26 μW·cm-2,and the removal rate of the DBP all can reach 90% after 30 min.The degradation rate of low concentration DBP in the tail water of municipal sewage plant was 85% by UV/H2O2,which lower than in distill water. |
