| 摘 要： | 以某实际合成氨化工厂废水为研究对象,进行高氨氮化工废水缺氧/好氧(A/O)工艺高效短程生物脱氮中试研究.试验结果表明:A/O系统经过90 d的运行,实现了稳定的短程硝化,并获得了稳定的有机物和氮去除.亚硝态氮积累率维持在80%以上,COD、NH4+-N和TN的去除率分别达到了95%、99%和80%.此外,机理分析表明,A/O中试系统获得稳定短程硝化的主要因素为较低ρ(DO)、较高ρ(FA)及适宜HRT三者的协同调控.

| Abstract: | A pilot-scale study on shortcut biological nitrogen removal from synthetic ammonia industrial wastewater was researched in an aerobic-anoxic system.The industrial wastewater contained a high NH4+-N concentration with 80-110 mg/L.Experimental results showed that a stable short-cut nitrification and denitrification was achived after a period of 90 d operation.The accumulation nitrite was keeping above 80%.The removal efficiencies of COD、NH4+-N and TN was 95%,99% and 80%,respectively.In addition,the mechanism analysis showed that the main reason for getting the stable short-cut nitrification and denitrification in the pilot system was attributed to the collaboration of low dissolved oxygen(DO),high free ammonia(FA) and appropriate hydraulic retention time(HRT). |
