Effect of Carbon Source Type Selection on Nitrogen Removal Efficiency in Denitrification System of Sewage Treatment Plant
In this paper,the effects of different carbon source types on nitrogen removal efficiency in denitrification system of sewage treatment plant were studied.The effect on nitrogen conversion during denitrification was evaluated by comparing the results of experiments using different carbon sources,such as ethanol,formic acid,and lactic acid.It was found that there were differences in the performance of denitrification systems among different carbon source types,and ethanol exhibited higher nitrogen removal efficiency.Therefore,the influence of carbon source type on nitrogen removal efficiency should be fully considered when designing and optimizing the denitrification system of sewage treatment plants.
