  • 摘要: 针对贵阳市朱昌镇茶饭村废弃石硐煤矿废水Fe、Mn浓度超标的问题，通过构建多级复氧反应-垂直流人工湿地系统对废水进行综合治理，并在多级复氧反应池内添加立体弹性填料对系统进行优化；研究系统优化前后对Fe、Mn、SO42-及重金属的去除效果。结果表明：pH从进水的5.60~6.58上升到出水的6.37~7.45，系统能有效去除Fe、Mn，Fe的去除率在99.10%以上，Mn去除效率为69.80%~100%，对Cu、Zn、Cd、As、Pb、Cr也具有较好的去除效果，但对SO42-的去除率仅为3.06%；添加立体弹性填料后沉淀池中SS浓度显著降低，Fe、Mn的去除率均可达到100%，Cu、Zn、Cd、As、Pb、Cr的去除率均有所提高，但对SO42-的去除效果仍不明显。多级复氧反应-垂直流人工湿地系统对煤矿废水具有良好的处理效果，添加立体弹性填料是优化系统的一项有效措施。
    Abstract: In view of the problems of excessive Fe and Mn in the wastewater from abandoned Shidong coalfield in Chafan Village, Zhuchang Town, Guiyang City, a multi-stage reoxygenation reaction-vertical flow constructed wetland system was built for the comprehensive management of wastewater, and the stereo elastic filler was also added in multi-stage reoxygenation reaction tanks to optimize the system. The removal efficiencies of Fe, Mn, SO42- and heavy metals were compared between the systems before and after optimization. The results showed that the pH increased from 5.60~6.58 for system influent to 6.37~7.45 for system effluent. The system had good performances on Fe and Mn removal, and their removal efficiencies were above 99.10% and 69.80%~100%, respectively. The relative good removal performance also occurred for Cu, Zn, Cd, As, Pb and Cr, but the removal efficiency of SO42- was only 3.06%. The addition of stereo elastic filler in the reaction tank could significantly reduce SS concentration in the sedimentation tank, the removal efficiencies of Fe and Mn could reach 100%, and the removal efficiencies of Cu, Zn, Cd, As, Pb and Cr could also be improved, but SO42- removal effect was still not satisfactory. The multi-stage reoxygenation reaction-vertical flow constructed wetland system has good performance on the treatment of coal mine wastewater, and stereo elastic filler addition in the reaction tank is an efficient measure for system optimization.
