沉积物疏浚是削减富营养化湖泊内源负荷的最为直接和有效的手段。分析了沉积物疏浚的效果和可能引起的风险;从外源污染、作业区域和深度、沉水植物3个方面探讨了影响沉积物疏浚效果的关键因素。最后指出,富营养化湖泊沉积物疏浚的重要原则是截断外源污染、划分作业区域、合理控制挖掘深度、创造适宜生境、恢复沉水植物、重构生态系统等。 |

Sediment dredging could remove the nutrients and pollutants accumulated in sediment,so it was considered to be the most direct and effective technology for reducing the endogenous pollutant load in eutrophic lake.The performance of sediment dredging and the possible risk it might lead were analyzed;the key factors that may influence the sediment dredging performance were discussed from 3 aspects of exogenous pollution,operational area and depth,submerged plant.Finally,the paper point out that the application principles of the sediment dredging were diverting sewage water discharge,locating removal areas,optimizing operation depths,creating suitable habitat,recovering submerged macrophyte and reestablishing the ecosystem. |
