| 以甲基橙染料配置成模拟牛仔服水洗废水,考察PAC、FeCl3、PAM、FeSO44种絮凝剂对该废水的脱色处理效果,并研究了每种混凝剂的反应最佳pH条件.实验结果表明,PAC在pH值7.5时,最大脱色率为61.8％;FeSO4在pH值为11.4时,最大脱色率为43.3％;FeCl3在pH值为7.5时,最大脱色率为68.8％,而PAM在不同pH下的脱色率最高仅为23.8％.4种絮凝剂在中性条件下,FeCl3对甲基橙染料模拟废水处理效果最好,最高脱色率为78％;对COD去除率低,最高去除率仍小于60％;对浊度去除率较高,最高去除率均可达到80％～93.88％. |

| This paper configured to simulate with methyl orange dye jeans washing wastewater,and investigate the PAC,FeCl3, PAM,FeSO4four decolorizing flocculant for the waste water treatment effect,and examined the effects of each coagulant optimum pH conditions. Pick to: this paper configured to simulate with methyl orange dye jeans washing wastewater,and investigate the PAC,FeCl3,PAM,FeSO4four decolorizing flocculant for the waste water treatment effect,and examined the effects of each coagulant optimum pH conditions. Experiments demonstrate: in neutral conditions,effect of FeCl3on simulation of methyl orange dye wastewater treatment is best,the highest decolorization rate was 78%,the COD removal rate is low,the highest removal rate is still less than 60%,the turbidity removal rate is higher,the highest removal rate can reach 80% ~ 93. 88%. At pH7. 5,the biggest decolorization rate of PAC is 61. 8%; FeSO4in the pH value of 11. 4,the biggest decolorization rate is 43. 3%; FeCl3in the pH value of 7. 5,FeCl3get biggest decoloring rate is 68. 8%,and PAM under different pH has the highest decolorization rate is just only 23. 8%. |
