Printing and dyeing wastewater has the characteristics of high content of organic pollutants, high difficulty in treatment, strong alkalinity, and high chroma. The electrochemical method for treating printing and dyeing wastewater has the advantages of simple equipment, no secondary pollution, thorough degradation, and high chroma removal rate. At present, crystal violet has been widely used as a dye in biological dyeing, medicine, leather and other fields. However, crystal violet is a toxic, high-residue "three-hazard" substance. Crystal violet wastewater discharged into the water without effective treatment will cause serious harm to the environment, which has driven the development of research on the degradation of crystal violet). We used a homemade Ti/Sno 2- Ruo2 ânodo para degradar águas residuais violeta de cristal . Os resultados mostraram que os fatores que afetam a degradação foram: densidade de corrente i, nacl no conteúdo da solução, pH e temperatura . sob as condições de i =2.5} ma/lm 2, pH =7, t =25 grau, a degradação foi de 40 minutos e as taxas de remoção de violeta e bacalhau de cristal nas águas residuais eram tão altas quanto 98 .} 9% e 85. 3%, respectivamente {{}}}} t Usado aM AMEM AMEM AMEM AMOM AMOM A HOMA Um sistema de eletrodo tridimensional para tratar águas residuais simuladas de metileno azul. Concluiu -se que o efeito de descoloração do eletrodo caseiro foi significativamente melhor que o de outros eletrodos. Após 60 minutos de eletrólise, a taxa de descoloração azul de metileno e a taxa de remoção de DQO podem atingir 87,83% e 74,45%, respectivamente.
O multi-componenteânodo de titânio revestido com rutêniohas good treatment effects on organic pollutant wastewater due to its good electrocatalytic activity, low working voltage and long life. From the aspects of electrode preparation conditions, active coating composition, electrolysis conditions, etc., domestic and foreign scholars have carried out in-depth research, among which the rare earth element doped modified ruthenium titanium anode is worthy of further exploration. When using ruthenium-coated anodes to treat high-chlorine heavy metal wastewater, chlorine evolution and oxygen evolution reactions occur simultaneously. The production of chlorine will damage the health of workers on the one hand, and reduce the current efficiency on the other hand, which is not conducive to energy saving. Coating a negatively charged active exchange coating on the surface of the anode coating produces electrostatic repulsion of chloride ions, which can effectively inhibit the production of chlorine. However, the binding force between the electrode and the active exchange coating is often weak, and the exchange coating is easy to fall off and inactivate. Therefore, enhancing the viscosity between the coatings and inhibiting the production of chlorine will become a future development tendência .
