摘要：
This paper investigates the effect of using sodium citrate（NaC6H5O6·2H2O）as sole carbon source for nitrate removal from drinking water.With sodium citrate as sole carbon source, batch experiments have been conducted to study the law of denitrification influenced by pH, C/N and temperature. Results show that a denitrification rate reaching 1.32 g NO-3-N /（g Biomass·d） was obtained when pH was at 7.5,C/N at 1.7（atom ratio）, and temperature from 20 ℃ to 30 ℃. The results also show that denitrification rate with sodium citrate as carbon source approaches to that with methanol as carbon source.
