摘　　要：采用好氧污泥协同微氧颗粒污泥技术对焦化废水中的氨氮进行处理,研究了其去除效果及影响因素,结果表明,微氧颗粒污泥+好氧污泥工艺对焦化废水中的氨氮有很好的去除效果,去除率可达80%以上;好氧阶段曝气时间和pH值对氨氮去除效果的影响较大,而整个系统运行稳定后停止运行1个月,对氨氮的去除效果无明显影响。The paper processes the ammonia nitrogen in coking wastewater with granular sludge＋ aerobic sludge,and studies its demolishing effect and influencing factors. Results show that：granular sludge＋ aerobic sludge technology has good effect for demolishing ammonia nitrogen in coking wastewater,and its demolishing effect reaches 80%;aeration time and pH value has great impact upon ammonia nitrogen demolishment at aerobic phase,and will have no impact upon ammonia nitrogen after one-month stable system operation.
