| 摘 要： | 采用湿式氧化(Wet Air Oxidation,WAO)工艺处理高浓度磷霉素制药废水,并对磷霉素制药废水WAO过程中总有机磷(TOP)和CODCr去除的动力学特征进行研究,定量表征了反应温度、氧分压对TOP和CODCr去除的影响。结果表明:WAO过程中TOP和CODCr的去除分为快反应和慢反应2个阶段,其去除过程较好地符合分段一级动力学模型,总体而言,TOP和CODCr的去除随着反应温度和氧分压的增加而增大,慢反应阶段TOP和CODCr的去除对反应温度和氧分压呈现较弱的依赖性。在氧分压为1.0 MPa条件下,TOP去除的表观活化能Eafast和Easlow分别为68.6和44.7 kJ/mol,COD去除的表观活化能Ea和Ea分别为41.0和24.5 kJ/mol。

| Abstract: | High concentration of fosfomycin pharmaceutical wastewater was treated by wet air oxidation(WAO).The kinetic characteristics of the removal of total organic phosphorus(TOP) and chemical oxygen demand(CODCr) in WAO of fosfomycin pharmaceutical wastewater were investigated.The effects of reaction temperature and oxygen partial pressure on TOP and CODCr removal were quantified.The results showed that the removal of CODCr and TOP in WAO was divided into fast and slow reaction steps and the removal process was w... |
