Abstract

In this study, the characteristic of CODCr distribution in hydraulic loom wastewater was investigated. The results show that most of CODCr materials exist in mesocolloid and suspending forms. Suspending and mesocolloid organics accounted for 31.5% and 46.9% of the total CODCr, respectively. The hydraulic loom wastewater was treated by the method of coagulation- ozonation- flotation process, and the results show that the optimal dosage of Al2(SO4)3 and ozone is 250 mg/L and 30 mg/L, in which conditions the removal efficiency of CODCr can reach to 87.0% . When the CODCr and turbidity of influent were 214mg/L and 63.9NTU, the corresponding effluent indexes can be reduced to 27.8mg/L and 2.5NTU, and the turbidity removal rate was 96.1%.
