| Abstract: | In this paper, a method of treating dyeing wastewater is introduced. It is based on the principle of galvanic raicro cell can be formed by corrossion of iron scrap in agueous solution. The experimental results indicated that the removal rates of COD were up to 50%～75%; the decolorization rates were above 90% and colourities were met the national standard for discharge. This method has many advantages: simple eguipment: convenienr for operation and management; lesser investment and land reguired; low operation cost etc. It is possible to he widely used in the treatment of dyeing wastewater. |
