| Abstract: | The effects of decolorization and CODer degradation in treating dyeing wastewater are studied by a combined process of Fenton reagent plus modified attapulgite with polydimethy Idiallyl ammonium ehloride（PDMDAAC）. The results showed that the decolorization rate can meet 99.4% and CODer degradation rate can meet 85.4% under the best conditions of 1.5g/L of the PDMDAAC-attapulgite ,temperature 25℃ ,pH value 8 to 10 and 15 rain of adsorption time. The discharge is up to the first grade standard of china. |
