This paper designed experiment installation to study the environmental behaviors of NH~+_4N in the vertical river bank filtration system.The NH_4Cl solution with a steady NH~+_4N concentration(18.27mg/L) served is taken as filtering solution.Through this experiment,the purifying mechanism of nitrogen pollution in the system was revealed.Results indicated that NH~+_4N takes part both in absorption and nitrification processes during the river bank filtration;owing to above effects,about 87 percent of NH~+_4N is cleaned though the river bank filtration system,but the nitrification capability is limited,some measures can be taken to enhance the cleaning capability,they include supplying dissolved oxygen and adding lime in the pollutant water.

采用自行设计的室内土柱实验装置,以恒定氨氮质量浓度为18.27 mg/L的氯化铵溶液为淋滤液,模拟氨氮在垂向河床中的渗滤过程,来探讨氨氮在垂向河床渗滤系统中的环境行为,借以了解河床渗滤系统对氮污染的净化机理。研究结果表明:氨氮在河床渗滤过程中分别参与吸附及硝化作用,主要发生在距离河床1~3 cm处;由于这两种作用的影响,该河床渗滤系统对氨氮的去除率达87%。同时还发现,该河床渗滤系统对氨氮的硝化能力有限,可以考虑向污水中补充溶解氧及添加石灰等强化措施来提高硝化能力。

The soil column was used to model the vertical infiltration of NO~-_3-N in the riverbank.In the experiment,the KNO_3 solution is added to the soil column to study the environmental behaviors of NO~-_3-N in the vertical system of riverbank filtration and the purification mechanism of nitrogen pollution.The results indicate that NO~-_3-N takes part in the dissimilation-deoxidization and de-nitrification during the process of River bank filtration.Under the influence of above processes,the NO~-_3-N is wiped...

The soil column was used to model the vertical infiltration of NO~-_3-N in the riverbank.In the experiment,the KNO_3 solution is added to the soil column to study the environmental behaviors of NO~-_3-N in the vertical system of riverbank filtration and the purification mechanism of nitrogen pollution.The results indicate that NO~-_3-N takes part in the dissimilation-deoxidization and de-nitrification during the process of River bank filtration.Under the influence of above processes,the NO~-_3-N is wiped off though the riverbank filtration,the removal efficiency reaches almost 100 percent.But dissimilation-deoxidization can lead that the rising of concentration of NH~+_4-N,which is the disadvantage of this process.

采用自行设计的室内土柱实验装置模拟硝态氮在河床中的垂向渗滤过程,以阶梯状加大浓度的硝酸钾溶液为淋滤液,研究了硝态氮在河床垂向渗滤系统中的环境行为,借以了解河床渗滤系统对硝态氮污染的净化机理。实验表明,硝态氮在河床渗滤过程中分别参与了异化还原作用及反硝化作用。在以上两种作用的影响下,河床渗滤系统对硝态氮的去除率高达100%。但是,异化还原作用却导致了地下水中氨氮浓度的上升,这是值得注意的不利因素。
