Abstract

Under the optimum combination conditions, the degree of nitrate contamination of groundwater has been investigated by column test to research the various effects of different filling modes towards denitrification. The research shows that under the environment of pH value is 7, with the temperature of 30°C and influent nitrate concentration 30mg/L, mixed filling of the hybrid filling has obvious advantages compared with sectional filling. In mixed filling, the nitrate removal effect is better and more stable with the removal rate being maintained at 95%. The accumulation of nitrite nitrogen mixed filling has been maintained at a low level, while nitrogen accumulation has been kept at a high level with the pH of the reaction system maintaining between 7 and 8
