Abstract: The study discusses the different performance of nitrate removal from groundwater with extra carbon source adding or not, which is carried out by using Hat Creek Coal and Bio-ceramic as filter bed in two separated processes. The experimental results indicated that both stuffing can be used as biological denitrification carrier filter with extra carbon source and removed the nitrate effectively. The extra carbon source does not affect the nitrate removal effect of Bio-ceramic. On the contrary, Hat Creek Coal played the role as both carbon source and biofilm carrier. For treating groundwater with low nitrate pollution, the quality of effluent could achieved GB/T14848-93Ⅲ standard of ground water.
