  • 摘要: 在中试条件下，考察了地下水中二价锰离子（Mn2+）对成熟石英砂表面滤膜去除氨氮（NH4+-N）的影响。结果表明，当进水Mn2+浓度不大于3.5 mg·L-1时，NH4+-N去除率随进水Mn2+浓度增大而增大。相应地，Mn2+的存在使得进水NH4+-N的浓度上限由2.51 mg·L-1提高到2.83 mg·L-1，且NH4+-N和Mn2+可实现同步去除。此外，进水Mn2+的存在（（2.1±0.1）mg·L-1）使得去除NH4+-N所需要的温度下降，这说明Mn2+对石英砂表面复合氧化膜催化NH4+-N氧化具有一定的促进作用，从而提高了NH4+-N在滤柱中的去除速率。
    Abstract: The effect of Mn2+ on the removal performance of NH4+-N by co-oxides film coated on silica sands was studied in a pilot-scale filter column. The experimental results showed that the removal of NH4+-N increased with the addition of Mn2+, while the influent Mn2+ concentration was below 3.5 mg·L-1. In the presence of Mn2+, the maximum limit of NH4+-N concentration in the influent increased from 2.51 to 2.83 mg·L-1. In addition, NH4+-N and Mn2+ can be simultaneously removed. When the influent concentration of Mn2+ was (2.1±0.2)mg·L-1, low temperatures were required with the effluent concentration of NH4+-N up to the standard compared with the case in absence of Mn2+, indicating that the existence of Mn2+ may increase the catalytic activity of co-oxides film for NH4+-N oxidation and consequently increase the NH4+-N removal rate.
