| 摘 要： | 通过一年来对武汉某湖水中COD的监测,分析COD变化规律与趋势,探讨其成因,结果显示:湖水中COD随着季节的变化呈明显变化的规律,其成因主要是:湖水及底泥中微生物的活性受季节的影响较大;天然降水量不同对湖水稀释程度不同;底泥的污染物释放量受温度影响。据此,提出保护湖水的措施。

| Abstract: | COD had been monitored for one year in one lake of Wu Han city,and the change laws of COD and trends were analyzed and the reasons were explored.The result showed that COD in water of lake changed with seasons obviously.The major reasons were that activities of lake water and microorganism in bottom silt were greatly affected by seasons.The different rainfalls had different abilities to dilute the lake water.The released capacity of pollutants in bottom silt was affected by temperature.The measures to prote... |
