| 摘 要： | 将中空纤维膜反应器和芬顿试剂结合脱除烟气中的Hg0。研究了不同参数以及SO2、NO和O2等杂质气体对Hg0脱除的影响。结果表明：随着H2O2浓度、Fe2+浓度、溶液初始pH和温度的增加，Hg0脱除率先增加后降低，其最佳工作条件是H2O2浓度为6 mmol/L，Fe2+浓度为9 mmol/L，溶液初始pH为2.5，温度为20℃；增大液气比和通过减小气相流量增大停留时间均对Hg0脱除有增强作用，当液气比超过0.11时，Hg0的脱除率不再增加；当气相流量为0.6 L/min时，Hg0脱除率超过85%；SO2、NO对Hg0的脱除有抑制作用，O2对Hg0的脱除几乎没有影响；还测定出温度20℃下中空纤维膜反应器的比相界面积a=270.29 m-1和传质动力学参数kL=8.13×10-4 m/s，kG=0.786×10-6 mol/（m2·s·Pa）。
