SBR法厌氧氨氧化脱氮的研究

The anaerobic ammonium oxidation (ANAMMOX) process is an economical and highly-effective nitrogen-removal technology. The experiments show that ：1) when the water inlet concentration is between 200 mg/L and 496.3mg/L, the nitrogen removal rate is 80% , the optimal water inlet concentration is 347.7mg/L . The optimal HRT should be 17h-24h and the optimal PH is 7-8.5, the optimal inner cycle flow velocity could be 24-96ml/min. The lower concentration of organic compounds is, the less effect on the reactor is. When the ratio of C/N is 2 , the nitrogen removal ratio can reach the maximum. 2)On this condition ,the reactor runs steadily and the nitrogen removal rate reaches around 80%., the TN volumetric charge rate is 588.00 mg/L•d and the maximum TN volumetric removal rate is 448.57mg/L•d.
