【摘要】：针对酸性矿井水地面处理的成本高、常规处理方法效果差等问题,提出以玉米芯为碳源、铁屑协同生物麦饭石固定颗粒为基质填料的升流式厌氧填料床(UAPB)和可渗透性反应墙(PRB)的井下原位处理方法。试验表明,UAPB与PRB反应器均具有较强的pH值提升能力,但PRB反应器抗污染负荷变化的能力更强,出水OD600值小,TFe去除率高,可达99.9%以上,且在70个孔隙体积数之后,PRB反应器中玉米芯缓释碳源(COD)浓度和SO_4~(2-)还原速率仍较高且稳定,平均值分别为1 136 mg/L和1 256 mg/(L·d),对Mn~(2+)的去除率也高出UAPB反应器15%。可见,PRB硫酸盐还原菌固定颗粒反应器更适合并下原位处理酸性矿井水。
[Abstract]:In view of the high cost of surface treatment of acid mine water and the poor effect of conventional treatment methods, the corncob is used as carbon source. In situ treatment of UAPB and PRB with iron chips in combination with biological Mailanshi fixed pellets as substrate fillers, both UAPB and PRB reactors have strong pH value lifting ability, the results show that both UAPB and PRB reactor have strong pH value lifting ability, and the results show that both UAPB reactor and PRB reactor have strong pH value lifting ability. However, the ability of PRB reactor to resist pollution load change is stronger, the removal rate of TFE in effluent is higher than 99.9%, and the concentration of corncob sustained-release carbon source and the reduction rate of SO4 / TFE in PRB reactor are still high and stable after 70 pore volumes. The average values of Mn~(2 were 1 136 mg/L and 1 256 mg/(L 路d0, respectively, and the removal rate of Mn~(2 was higher than that of UAPB reactor 15. It can be seen that the fixed particle reactor of sulfate-reducing bacteria is more suitable for the treatment of acid mine water in situ.
