A study on treating washing & bleaching waste water with electro-chemical oxidation

Electrochemical oxidation reaction with stainless steel electrode was used to treat the washing bleaching waste water, and the optimum process parameters were obtained as follow: space of electrodes 10mm, electric current density 15~ 20mA/cm2, pH neutral, the treating time 4h. Under these conditions the COD removal rate of wastewater is 92%, whereas the removal rate of COD is only 30% with using Ti-PbO2electrode.
