Sediment dredging can effectively lower the contents of nutrient,heavy metals and persistent organic pollutants in sediment,but resuspensiou of sedi- ment during dredging will induce the release of pollutants from sediment to the water column.
底泥疏浚的效果至今仍存在很大争议,其中之一是疏浚后所产生的环境效果有可能偏离人们的期望,疏浚能够有效的削减沉积物中营养物、重金属和持久性有机物等污染物含量,但疏浚过程中会引起污染物向水体释放,疏浚后的界面过程有可能对疏浚效果产生较大影响,底泥疏浚对水体富营养化的控制有成功的经验也有失败的教训,不同的湖泊疏浚后对营养盐释放的控制效果不同。
Results show that the water quality of Nanhu lake in Changchun is significantly improved after sediment dredging from 2000 to 2002,and the indices of water quality in water lily area even reach or approach to the third level of GB3838-2002.
结果显示,南湖在经过2000~2002年的底泥疏浚治理后,水质状况有了显著的改善,特别是荷花区水域的一些监测指标已经达到或接近GB 3838—2002Ⅲ类水体标准值;但游泳区和湖心区的水质仍表现出富营养化,水体中TP,TN超标现象较为严重。
