火力发电厂的脱硝系统经常因为控制不好，氨逃逸浓度会增加，进而导致排放废水氨氮浓度超标。针对内蒙古某电厂氨氮超标问题，通过对系统全面分析诊断，经过化验分析，查明超标原因，采取了调整脱硝系统运行方式和折点氯化法除氨氮的处理措施，解决了氨氮超标问题。该方案效果明显，操作灵活，投资小，基本不占用场地，维护方便，有较高的经济效益，降低了环保风险，值得借鉴和推广。

Not well controlled denitration system in thermal power plant can cause ammonia escape concen-tration increase, which leads to ammonia nitrogen concentration in discharged wastewater exceed the standard. The reasons caused the ammonia nitrogen concentration in the wastewater discharged from a thermal power plant in Inner Mongolia exceeded the standard were found through the analysis and diagnosis on the wastewater treat-ment system. Adopting the measures such as adjusting operation mode of denitration system and using break-point chlorination process to treat ammonia nitrogen, the problem was solved. The said process had advantages of obvious effect, flexible operation, small investment, basically no space occupation, convenient maintenance, high-er economic benefit and lower environmental risk, which was worthy of being referenced and popularized.
