The results show that, the nitrate-N concentration in groundwater in the reed area was 0.2~0.8mg/L and significantly lower than that in surrounding wells (more than 20mg/L), and the reed wetland can remove nitrate pollution in shallow groundwater. The distribution of denitrifying bacteria showed obvious rhizosphere effect, and the higher biodenitrification in natural reed wetland was related to the distribution of denitrifying bacteria. There was a negative relationship between the nitrate-N concentration and the number of denitrifying bacteria in groundwater.
