| 摘 要： | 采用酸析—撞击流旋转填料床( IS-RPB)强化Fenton试剂氧化法预处理二硝基甲苯(DNT)生产废水.最佳工艺条件为:酸析工段废水pH 1.0,IS-RPB转速1 500 r/min,FeSO4加入量0.06 mol/L,H2O2加入量0.45mol/L,反应温度40 ℃,反应时间4h.在该条件下处理DNT生产废水,COD去除率可达98.95％,硝基化合物去除率达98.32％,BOD5/COD为 0.65.经该方法预处理后的DNT生产废水可适用于生化法进行后续处理.

| Abstract: | Dinitrotoluene(DNT) production wastewater was pretreated by acid precipitation-enhanced Fenton reagent oxidation in impinging stream-rotating packed bed(IS-RPB).The optimum process conditions are as follows:wastewater pH in acid precipitation process 1.0,IS-RPB rotation speed 1 500 r/min,FeSO4 dosage 0.06 mol/L,H2O2 dosage 0.45 mol/L,reaction temperature 40 ℃,reaction time 4 h.Under these conditions,the removal rates of COD and nitro compounds from DNT wastewater can reach 98.95% and 98.32% respectively,and the BOD5/COD is 0.65.The pretreated DNT wastewater can be further treated by biochemical process. |
