摘要:水体中存在的微量持久性有机污染物对人类的正常生命活动构成了严重威胁。电催化氧化技术因具有适应性广,氧化性强,无二次污染,反应迅速,设备及其操作简单等优点而日益成为难降解有机废水处理领域的研究热点[1]。本实验采用电催化氧化法对高浓度有机制药废水进行处理, 探究了废水的状态、种类、PH 值、电压、时间、无机盐的投加等因素对COD、吸光度去除率的影响。 结果表明, 这种方法能有效去除废水中的COD, 特别是时间、无机盐的投加、废水的种类这三个因素对COD 的去除率影响较大。同时也采用了物理吸附法与电催化组合的方法,实验结果表明,在适宜的条件下,COD的去除率可以达到80%以上,由此可见,开展电催化氧化法处理难生物降解有机废水的研究开发工作很有必要。21096

Abstract
The presence of trace water POPs pose a serious threat to human normal life activities. Electro catalytic oxidation technology has wide adaptability, strong oxidation, no two pollution, rapid response, the advantage of equipment and simple operation and become refractory organic wastewater treatment field. This experiment adopts the electro catalytic oxidation method for treatment of high concentration organic wastewater, researched the influence of state, types, PH values of voltage, time, water, inorganic salt dosage and other factors on the removal rate of COD. The results show that, this method can effectively remove COD in wastewater, especially time, inorganic salt type, investment and waste of these three factors on the removal rate of COD influence. At the same time, the method of physical adsorption and catalytic combination is also used, the experimental results show that, under appropriate conditions, the removal rate of COD can reach more than 80%,, electro catalytic oxidation process to carry out research and development work on biodegradation of organic wastewater is necessary.
Key Words: electro catalysis, pharmaceutical wastewater, anodic oxidation, refractory organic wastewater
