It is difficult to treat printing and dyeing wastewater, for printing and dying wastewater features complex composition, high chromaticity and many toxic substances.The paper studied the effect of the compound of inorganic and organic coagulant with Fenton reagent on the treatment of printing and dyeing wastewater. The effect of other factors were also investigated, including pH value, flocculants, Fenton reagent and reaction time. The results showed that, under the conditions of room temperature, pH 9, PAFCS dosage 100mg/L, PAMC 4mg/L, pH 4, H2O2 dosage 1.0mL/L, FeSO4•7H2O dosage 150 mg/L, the reaction time 60 min, the CODCr removal was high over 91%, and the color was also significantly removed.
