| 中文摘要: |
| 选用4种方法测试污水处理厂的沉砂池、初沉池、曝气池、二沉池工艺段的氨气浓度、污水指标和氨气排放因子，结果表明：氨气排放浓度与污水中氨氮浓度及总氮浓度有较好的线性关系，氨气很大程度上来自水中氨氮或总氮的转化；其中挥发速率模型法现场实测获得的氨气排放因子最高，为0.919 g/m3。 |
| 英文摘要: |
| Four test methods were chosen for determining ammonia concentration, sewage index and ammonia emission factors from grit chamber, primary settling tank, aeration tank and secondary settling tank of the sewage treatment plant. The results showed that the ammonia emission had good linear relationship with the concentration of ammonia nitrogen and total nitrogen in the wastewater. Most ammonia was transformed from ammonia nitrogen or total nitrogen in the tap water. The ammonia emission factor obtained from ammonia volatilization rate model was 0.919 g/m3, which was the highest among the four methods. |
