Effects of Solid Organic Carbon on Nitrate Remove in Groundwater

Abstract:

In groundwater, the lack of carbon source is a key problem of in-situ denitrification. It is very important to choose appropriate solid carbon-source materials. In this work, wheatstraw and sawdust were selected as potential carbon sources to evaluate the performance for in-situ biological denitrification in groundwater by column experiments. The results showed that sawdust was a suitable corbon source with less release of nitrogen compounds and relatively stable release of organic carbon, compared with wheatstraw, and was applicable for further use as a filling material in in-situ ground water bioremediation.
