摘　　要：以某炼油厂废碱液为碳源,采用短程硝化-反硝化法处理低碳高氨氮废水。实验结果表明,在反应温度为(25±1)℃、废水pH为7.7～8.3、DO小于0.5 mg/L、运转周期为6 h(曝气时间4 h、缺氧时间2 h)的条件下,反应7 d后,出水ρ(NH_3-N)约为0.2 mg/L,TN约为1.69 mg/L、出水COD降至156 mg/L。The wastewater containing low carbon and high ammonia nitrogen was treated by shortcut nitrification-denitrification process with waste lye from refinery as carbon source. The experimental results indicate that under the conditions of reaction temperature （ 25±1 ）℃, wastewater pH 7.7 - 8.3, DO less than 0. 5 mg/L, running period 6 h （aeration time 4 h, anoxiating time 2 h） and running time 7 d, the p（ NH3-N）, TN, COD of the effluent are 0.2, 1.69, 156 mg/L, respectively.
