摘要
研究生物脱氮工艺在处理低碳氮比工业废水时,低溶解氧(DO)条件下亚硝酸盐积累的情况。试验结果表明,系统在DO为1.0mg/L条件下有效去除氨氮的同时,能够实现稳定持久的亚硝酸盐积累,平均亚硝化率达到82.1%,系统氨氮去除率超过95%。
Nitrite accumulation was studied under the condition of low dissolved oxygen（DO） during the biological nitrogen removal treatment of industrial wastewater with low C/N ratio.As indicated by the experimental results,the system could realize stable and lasting nitrite accumulation with high ammonia removal efficiency at DO = 1.0 mg/L,and the system achieved an average nitrite accumulation ratio at 82.1% and ammonia removal rate of over 95%.
