浅水湖泊生态清淤施工影响分析OA

Taking Changdang Lake as an example,the impact of ecological dredging construction is studied.Through a combination of on-site sampling and simulation experiments,the scope of impact of dredging construction,the degree of impact on water quality,and the timely removal of sediment pollution are analyzed and evaluated.The results indicate that the construction impact range of the 200 m3/h type environmentally friendly cutter suction dredging ship in Changdang Lake does not exceed 50 m.The concentration of suspended solids and pollutants in the water body can recover to near the background level about 0.5 hours after disturbance stops,and the sediment pollution is effectively removed after dredging.
