%X The simultaneity nitrification and denitrification (SND) was studied in a loop reactor. In the experiment, the research of biological nutrients removal was carried by changing carbon source and the method of adding carbon source, and the concentration of NOx--N and the dissolved oxygen(DO) level were also inspected. The results indicated that the removal of NH4+-N could be enhanced by adding carbon source with COD 800mg/L+800 mg/L. And the concentration of NH4+-N in outlet was lower than 3mg/L; Lower DO level in the reactor could be made easily by using difficultly reduced carbon source. It was useful to improve the biological nutrients removal. When using ethanol or glycerol as carbon source, the removal efficiency of NH4+-N was better than using glucose.
