| 中文摘要: |
| 本次实验在室内静态模拟条件下，研究不同的温度和溶解氧浓度水平下巢湖市东环城河底泥COD、NH3-N、TN和TP释放特性。结果表明：温度为20℃时，COD释放量最大，10℃时最小。厌氧状态下COD释放量远大于好氧状态；随着温度的升高，底泥NH3-N、TN、TP释放量不断增大，上覆水中溶解氧浓度逐渐降低，底泥NH3-N、TN、TP释放量逐渐增加；上覆水体NH3-N含量与TN浓度呈正相关。 |

| Under the condition of indoor static simulation，this experiment researches the properties of sediment in the east of the round-the-city river in Chao Hu release COD、NH3-N、TN and TP， at different temperatures and dissolved oxygen concentration levels. Results show that: when the temperature is 20℃，the quantity of sediment release COD reaches a maximum，the 10℃ is minimum. And the quantity of releasing COD in anaerobic condition is far greater than the aerobic condition. With the increase of temperature，the release of NH3–N、TN、TP in sediment continuously increased，and when the overlying water dissolved oxygen concentration decreases gradually，the quantity of Sediment release NH3-N、TN、TP is gradually increasing.The correlation with NH3-N content and concentration of TN are positively significant. |
