| Abstract: | A composite process composed of hydrolytic acidification-contact oxidation-air flotation for treatment of printing and dyeing wastewater was applied on the basis of the characteristics of this kind of wastewater.The running result showed that when the raw wastewater has average concentration of 1 100 mg/L, 294.5 mg/L, 197.2 mg/L and 580 times for COD_ Cr,BOD_5, SS and colourity, the technique could achieve a removal efficiency of 89.6%, 89.4%,71.0% and 87.8% respectively.All the quality indexes of the treated water could meet the second-order of “Discharge Standard of Industrial Pollutant of Printing and Dyeing”(GB4287-92). |
