| Abstract Scope |
Electroplating industry is one of the surface treatment industries with strong versatility and wide application range. Electroplating process mainly includes pretreatment, electroplating and post-treatment. In order to achieve specific effects, additives such as brightener, sub brightener, surfactant and others are indispensable in the electroplating process. These organics usually have poor biodegradability. In addition, due to the high toxicity of electroplating wastewater, biological treatment has great limitations on their decomposition. These organic compounds cause the increase of COD in electroplating wastewater, which seriously pollutes the membrane system and hinders the development of electroplating wastewater reuse process. In this study, ozone is investigated for the oxidation of organics and the results are discussed. |
