| 摘 要： | 通过实验室模拟研究了覆土法对三峡大学文思湖底泥中污染物缓释的可行性.通过监测上覆水体中总氮、总磷和有机质浓度水平监控底泥中污染物释放过程,发现底泥覆土之后上覆水体中总氮、总磷和有机质浓度水平均显著降低,与覆土材料自身向上覆水体释放的氮源、磷源和有机质浓度水平相当.结果表明,覆土可以明显抑制底泥中污染物向上覆水体的释放,因此通过覆土以抑制底泥污染物释放可行.

| Abstract: | The feasibility of pollutant release restraint from sediment of Wensi Lake by covering with soil was studied.The pollutant releasing process was monitored by detecting the concentrations of total nitrogen,total phosphorus and organic matter in the up-covered water.The up-covered soil could depress the releasing ability of nitrogen,phosphorus and organic carbon out of sediment;and the results show that the concentrations of total nitrogen,total phosphorus and organic matter in the up-covered water from sedim... |
