摘要
以大米淀粉为吸附剂,在微旋流器中吸附亚甲基蓝水溶液模拟的印染废水。通过单因素试验分析淀粉浓度,分流比和进料流量对吸附效率和分离效率的影响规律。运用响应面分析法,对试验参数进行优化。结果表明:淀粉浓度、分流比和进料流量对吸附效率和分离效率均有影响,对吸附效率影响的大小顺序为淀粉浓度>分流比>进料流量,对分离效率影响的大小顺序为分流比>进料流量>淀粉浓度。综合考虑吸附效率和分离效率后得到最佳参数条件为:淀粉浓度1. 0%,分流比19%,进料流量1 080 kg/h,该条件下吸附效率为69. 2%,分离效率为74. 3%。
Rice starch was used as an adsorbent to adsorb the dyeing wastewater simulated by methylene blue in mini-hydrocyclone. The single experiments were used to explore the effect of starch concentration,split ratio and feed flow rate on the efficiency of adsorption and separation. Moreover,the response surface analysis method was used to optimize process parameters. The results showed that the starch concentration,split ratio and feed flow rate all influenced the efficiency of adsorption and separation. The order of effect on adsorption efficiency was as followed： starch concentration split ratio feed flow rate,and the order of effect on separation efficiency was as followed： split ratio Feed flow rate starch concentration. The optimal parameters condition obtained by response surface method was as followed： starch concentration was 1. 0%,split ratio was 19%,and feed flow rate was 1 080 kg/h. Under the control of these conditions,the efficiency of adsorption and separation was69. 2% and 74. 3%,respectively.
