摘要:
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18.27mg/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1~3cm 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。
Abstract:
This paper designed experiment installation to study the environmental behaviors of NH+4N in the vertical river bank filtration system. The NH4Cl 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 clean- ing capability, they include supplying dissolved oxygen and adding lime in the pollutant water.
