摘　　要：This paper presents lab-scale experiment carried out to evaluate the correlation between ammonia nitrogen （NH3-N） and p-toluidine using sequencing batch reactor treating synthetic p-toluidine wastewater. The profiles of NH3-N and p-toluidine were traced under the concentration of sucrose in the influent varied from 0 to 500 mg/L, aerated airflow varied from 0.6 to 1.2 L/min and temperature varied from 10 to 25℃, respectively. The results showed that the concentration of NH3-N turned from increase to decrease when p-toluidine was nearly completely biodegraded, so the profile of NH3-N could clearly indicate the endpoint of p-toluidine biodegradation. And the profile of NH3-N was not influenced by the sucrose in the influent, aerated airflow and temperature. It is showed that using ammonia nitrogen as monitoring and control parameter is feasible and reliable and has promising application in amine wastewater treatment by SBR.This paper presents lab-scale experiment carried out to evaluate the correlation between ammonia nitrogen （NH3-N） and p-toluidine using sequencing batch reactor treating synthetic p-toluidine wastewater.
