摘要：本文闡述了電化學作用下印染污水處理降低COD的具體操作方法和機理。實驗采用不同的處理條件進行分析，從而選擇最佳的處理條件，使廢水處理效果達到較好的水平。同時，本文還將電化學法去除COD與通過加入Fe2SO4去除COD的方法進行對比，分析兩種方法的可行性和效果，得出的具體結果如下：電流密度=2020mA/cm2，t=4h，r=150min/min。COD降解率為62.5%。污水顏色由墨黑色變為透明無色。而Fe2SO4在加入量為4.2g/50ml達到極值，其COD降解率為43.75%。污水顏色由墨黑色至微綠色。

Electrochemical treatment of dyeing the optimization of sewage

Abstract ：In this paper,the electrochemical treatment of the dyeing wastewaters are investigated in detail of the way to reduce the COD,The different operating conditions of the treatment process were studied.Also,this paper compared the quality of the electrochemical treatment and the chemical treatment by adding the FeSO4 to the wastewaters,anlaysing the reality and compatibility of both method.The result are showed below:With the  is 2020mA/cm2，t=4h，r=150min/min,the effort of the electrochemical treatment is in the best way,COD reduction is about 62.5%,the color turns from black to none.While adding is FeSO4 reached the peek date,the reducion is 43.75%.The color tunrs from black to green.
