摘　　要：某氮肥企业排放的废水中有机物与氮素的比值只有1-2，利用现有的脱氮方法与工艺处理很难使废水达标排放。采用缺氧-厌氧-微氧-好氧新工艺对氮肥厂低碳氮比废水进行生物脱氮，在进行第一阶段的影响因素试验研究表明，当水温20℃、好氧区溶解氧1．8mg／L、污泥龄20d时，出水水质可达到《污水综合排放标准》（GB8978-1996）的一级排放标准。The ratio of organic matter to nitrogen is low in the wastewater of a certain nitrogenous fertilizer enterprise, only 1 -2 and it is difficult to reach the discharge standard with existing methods. To the Low C/N wastewater,having the denitrification experiment and study with anoxic -anaerobic -micro oxygen - aerobic process, and the influence factors of first stage experiment result indicate that the effluent quality can achieve the I - class criteria in integrated wastewater discharge Standard （ GB 8978 - 1996） when the temperature is 20 ℃ , DO of aerobic zone is 1.8 mg/L and sludge age is 20 d.
