摘要:
以硝酸蒸馏尾液为研究对象,考察了SG反硝化菌在A/O系统中的脱氮效果。研究结果表明:在进水pH为0.36、反应温度30 ℃、C、N质量比为3.0、反硝化停留时间为35 h,SG反硝化菌种投加量为5 mL/L、氢氧化钠投加量为1.8 g/L的实验条件下,装置连续运行30 d,硝酸蒸馏尾液TN去除率达99%,ρ(出水TN)≤40 mg/L,达到国标新排放标准。
Abstract:
The efficiency of nitrogen removal from distillation residue of nitric acid was investigated by using 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 35 h, adding amount of SG denitrifying bacteria 5 mL/L, adding dosage of sodium hydroxide 1.8 g/L andcontinuous operation of the unit for 30 d, 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 40 mg/L, which meets the newest international discharge standard.
