3,5,6-三氯吡啶-2-醇钠废水处理研究

Research on Treatment of Sodium 3,5,6-Trichloropyridin-2-ol Wastewater

3,5,6-三氯吡啶-2-醇钠生产过程中产生的废水具有污染性强和难降解的特性。采用铁碳微电解工艺对其进行处理,考察了废水p H、铁碳质量比、铁碳加入总量、停留时间等因素对COD的影响。结果表明,在最优工艺条件下,COD总去除率可达52.8%。

There is a large amount of wastewater from the production of 3, 5, 6-triehloropyridin-2-ol, which is of characteristics of high pollution and difficult to be treated.Here, the processes of iron carbon micro-electrolysis was used to treat wastewater.The influences of several parameters such as pH of wastewater, mass ratio and dosage of FedC, residence time on COD have been studied.It was revealed that under the optimal eunditions, the total removal rate of COD reached 52.8%.
