摘要
Abstract
A type of amphoteric chitosan was prepared and characterized. When 100 mg/L of the ampho?teric chitosan was used alone as flocculant for the treatment of activated red X-3B simulated dyeing wastewa?ter (pH=7), the decolorization rate was 94.9%, the removal rate of COD was 76.8%. A type of composite floc?culant of amphoteric chitosan/bamboo charcoal was also prepared, when the dosage of the amphoteric chito?san was 200 mg/L, the dosage of bamboo charcoal was 50 mg/L, the decolorization rate of the composite floc?culant on treatment of simulated dyeing wastewater was 98.2%, the removal rate of COD was 82.6%. More?over,the pH of wastewater showed little influence on the flocculation effect.关键词
