Based on the characteristics of dye-containing wastewater, the effectiveness of chromaticity and COD removal from dye containing wastewater by means of chemical oxidation flocculation has been studied. The two factors (pH and flocculant quantity) have been studied. The results show that the COD and chromaticity removal rate are 97% and 86% respectively under the conditions that pH is greater than 10, flocculant dosage is 0.03% of the wastewater, flocculation and deposition time are 6 min and 35 min respectively. It has proved that the technology is feasible for dye-containing wastewater. The process is characterized by simple equipment, stable operation, easy control and low operation cost.
Key words: oxidation-flocculation; dye-containing wastewater; removal ratio
