| Abstract: | Under the operational condition, synthetic wastewater was used in the experiments to investigate the performance of nitrogen removal by the BICT of the reactor.The results of the experimental study can be concluded as follows.The nitrogen removal mechanism of BICTP is sequential nitrification and denitrification.A separte attached growth reactor was adopted to enhance the function of nitrification and increase the efficiency and the stability of nitrogen removal process.Under suitable conditions,the removal rate of TN(total nitrogen) can reach over 80%, and the effluent concentration of TN can be controlled below 15 mg/L. |
