Study on Start-up of ANAMMOX Bioreactor Using Mixture of Leachate

The feasibility of starting up anaerobic ammonia oxidation(anammox) reactor with the mixture of leachate has been study in the experiment.The results show that anammox reactor can be started up successfully within 161 days with the method of high rate cultivation.The ratio of removal ammonia nitrogen to nitric nitrogen reduces gradually and tends to be steady with the advance of start-up process of the Anammox reactor.The average ratio of removal nitric nitrogen to ammonia nitrogen is 1.19,and alkalinity and pH value of influent and effluent tents to be unanimous under the steady phase of Anammox activity.The ratio of nitric nitrogen removal to ammonia nitrogen as well as the change of alkalinity and pH value in the bioreactor can indicate the status of ANAMMOX bioreactor start-up process.
