摘要
Abstract
The efficiency of nitrogen removal from distillation residue of nitric acid was investigated by u-sing SG denitrifying bacteria in A/O system. The results show that when the experimental conditions are: pH in feedstock stream at 0. 36, reaction temperature at 30 ℃ , C, N mass ratio of 3. 0, residence time of denitrifying for 35h, adding amount of SG denitrifying bacteria 5mL/L, adding dosage of sodium hydroxide 1. 8g/L and continuous operation of the unit for 30d, the total nitrogen removed reaches 99% in the distillation residue of nitric acid and the total nitrogen in the effluent stream is not more than 40mg/L, which meets the newest international discharge standard.关键词
