摘要
[目的]研究文思湖底泥TP的释放规律。[方法]采用室内模拟试验,研究环境因子(水土比、温度、pH、扰动强度、供气量)对文思湖底泥释放总磷(TP)的影响。[结果]水土比越大,底泥释放TP的量越小;水温升高能加速底泥中磷的释放;上覆水pH=6时底泥TP释放量最低;扰动上覆水体会加快磷的释放;溶解氧(DO)较低时,底泥TP释放量更大。[结论]该研究为文思湖的污染治理提供了科学依据。
[Objective] The study aimed to analyze the release of total phosphorous from Wensi Lake sediment into water.[Method] Though simulation experiments in a laboratory,we studied the effects of various environmental factors like water-soil ratio,water temperature,pH,disturbance and dissolved oxygen（DO） on TP release from Wensi Lake sediment.[Result] The higher the water-soil ratio,the less TP released from the sediment;temperature increase sped up TP release from the sediment;when pH of overlying water was 6,the amount of released TP was the lowest;disturbing the overlying water accelerate TP release from the sediment;the lower the DO content,the larger the released TP.[Conclusion] The research provided scientific references for controlling the pollution of Wensi Lake.
