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.
