【Abstract】 Simulated wastewater of reactive light_yellow K 4G dyes was treated by multi_electrodes method in the research. Various factors influencing decoloration rate and removal rates of COD Cr were discussed. The result showed that decoloration rate and removal rates of COD Cr were improved when we added quantity of activated carbon, extended duration of electrolysis or magnified density of electric current, added iron filings. Decoloration rate and removal rates of COD Cr were varied when electrical conductivity was varied,and the influence level of experimental factors on decoloration rate and removal rates of COD Cr were compared by orthogonal experiment.更多还原
