Abstract
Cationic polymer flocculant was synthesized using epichlorohydrin, diethanolamine and cross⁃linking agent hexamethylendiamine as materials. The effects of molar ratio, reaction time and temperature on decolorization rate of acid black dye were discussed. Meanwhile, the structure of polymer flocculant was char⁃acterized by FT- IR, and the flocculant was used for treatment of acid black dye flocculation. Under 100 mg/L of dye mass concentration, the effect of flocculant dosing amount, pH of dyeing wastewater and standing time on decoloration of dye were studied. The optimal decoloration process was determined: the dosage of flocculant was 350 mg/L, pH was control ed at 6~7, and maintaining the standing time for 25 min. The rate of decoloration could reach 95.1%. Compared with polyacrylamide and poly aluminium chloride flocculant on the market, under the same conditions, the decolorization rate and COD removal efficiency of cationic polymer floc⁃culant increased notably.关键词
