An Experimental Study of Microbial Removal of Nitrogen Pollutant from Groundwater
地下水氮污染治理的探索试验

Nitrogen pollution has widely occurred in the groundwater of Shijiazhuang piedmont plain in front of the Taihang Mountain. The authors added microbial nitrogen_removing solvent and ethanol carbon to the seepage media in a sand flume resembling the prototype of seepage field. This means conducting an experimental study of microbial removal of nitrogen under different hydrodynamic conditions. The results show that the microbial nitrogen_removing technique could effectively eliminate nitrogen pollution in the groundwater adjacent to the injection well and in a certain distance of the lower reach in a certain period of time. This may provide a scientific basis for in situ treatment of nitrogen_polluted groundwater.
