| 摘 要： | 利用纳米TiO2进行超声协同光催化处理焦化废水实验,探讨了其协同作用机理,考察了TiO2加入量、超声功率、pH值对CODCr和NH4+-N去除效果的影响。分析了曝气、H2O2或Fenton试剂与超声和光催化的协同作用机理,研究了对CODCr和NH4+-N去除效果的影响。结果表明利用超声协同光催化处理焦化废水,CODCr和NH4+-N的去除率显著提高,许多难生物降解有机物被降解去除。

| Abstract: | Photocatalytic treatment of coking wastewater by nano-TiO2 synergized with ultrasonic was examined,and the synergistic effect mechanism was discussed.Effect of amount of TiO2,ultrasonic powder and pH value on removal of CODCr and NH+4-N was investigated.The synergistic mechanisms of ultrasonic,photo-catalysis with aeration,H2O2,or Fenton reagent were analyzed,and the effect on removal of CODCr and NH+4-N was discussed.Experimental results show that when coking wastewater was treated by photocatalysis synerg... |
