| 摘 要： | 采用间歇式泡沫分离法处理含Cr~(6+)废水,考察了各因素对Cr~(6+)去除效果的影响。通过正交实验分析确定的废水处理最佳工艺条件:废水pH 4.00,气体流量0.90 L/min,阳离子表面活性剂加入量300 mg/L。进水Cr~(6+)质量浓度为10 mg/L时,间歇运行的Cr~(6+)去除率为97.80%,连续运行的Cr~(6+)去除率为95.89%,出水均可达标排放。动力学实验结果表明,泡沫分离法去除Cr~(6+)的过程符合一级动力学的特征。对泡沫分离柱放大后的废水连续流实验分析结果表明,泡沫分离Cr~(6+)的效果比较稳定,但分离设备对废水处理效果有一定的影响。

| Abstract: | Cr~(6+)-containing wastewater was treated by intermittent foam separation process.The factors affecting the Cr~(6+)removal efficiency were researched.The optimal operating conditions determined by orthogonal experiments are as follows:wastewater pH 4.00,gas flow 0.9 L/min,cationic surfactant dosage 300 mg/L.When the mass concentration of Cr~(6+)in the influent is 10 mg/L,the effluent can meet the national discharge standard with 97.80% of Cr~(6+)removal rate for intermittent running and 95.89% for continuou... |
