Textile processing wastewater treatment by high voltage discharge

Textile processing wastewater requires various treatment methods. A high voltage discharge was used to treat some typical types of textile processing wastewater using two kinds of electrode systems, a multineedle to plate system and a needle to needle system. The results show that the treatment reduced the chromaticity of the samples while increasing the total chemical oxygen demand (COD) of the samples. The ozone, ultrasound and ultraviolet radiation produced by the high voltage discharge effectively destroys the chromophoric group of the dye and the naphthalene or benzene rings. The results were to some degree influenced by the electrode shape. The study shows that high voltage discharges can effectively treat textile processing wastewater.
