Study on the Selected Lignite Using as Organic Carbon in the Treatment of Nitrate Contaminated Groundwater

Abstract:

Twelve kinds of lignite from different areas of China were used for the study of solid-phase biodenitrification. The amount of released carbon, rate of nitrate removal and acute toxicity were examined for all the lignite samples. The results showed that the averaged nitrate removal rates of lignite from Wangniutan and Zhangjiakou were higher than the others, which can reach above 30%. The averaged removal rates of lignite from Zhaotong, Aksu and Faku were more than 20%, and others were less than 10%. Lignite from Wangniutan, Zhangjiakou, Aksu and Faku were more suitable fillers as biodenitrification carbon for its less luminescent bacteria acute toxicity.
