Different adsorbents,oxidants,and aeration methods were used to study the chromaticity removal of flotation wastewater.The method of first adding Ca(ClO)2 and then adding activated carbon(40～80 mesh)was determined to jointly treat the chromaticity of flotation wastewater.The results showed that in 200 mL of raw water,the optimal dosage of activated carbon was 1 g,and when the usage of Ca(ClO)2 was reduced to 1 g,the chromaticity treatment of flotation wastewater could effectively remove the chromaticity,and the pH value of the treated solution met the discharge standards.
