【摘要】 选用角蛋白为改性主体,考察了pH、用量、絮凝时间和染料初始浓度对直接墨绿染料废水脱色率的影响。当染料废水絮凝剂用量为300 mg/L,PH为3.5,絮凝时间为4 h,染料初始浓度在100 mg/L时,两性角蛋白絮凝剂对制革过程产生的直接墨绿染料废水的脱色率达到96.4394%。在上述最佳条件下测定其他染料的脱色率,如直接红棕、直接湖蓝、直接皂黄、金黄、直接冻黄。其中,直接红棕的脱色率达到92.2456%。实验证实角蛋白絮凝剂对废水处理有良好的效果。更多还原

【Abstract】 The factors affected the flocculation efficiency were investigated,include optimal pH、 dosae、flocculation time and initial dye concentration.The experimental results show that:the self-made amphoteric keratin flocculant has good effect on direct blackish green dye wastewater from leather making process.The flocculant doage 300 mg/L,the esolution pH 3.5,the flocculant time 4 h and the nitial dye concentration 100 mg/L,the removal rate of suspended solids can reached at 96.4394%.Under the best conditions to determine other dye decolorization rate,as red brown,direct lake blue,direct soap directly frozen yellow,golden yellow,and diect yellow,the direct red brown has the higher decolorization rate and can reached at 92.2456%.更多还原
