摘要:
以太湖竺山湖清淤工程中的气力泵清淤与绞吸式清淤施工为对象，分析清淤工程中2种船型对周围水体的悬浮物、总磷、总氮以及氨氮等指标的影响，比较分析了绞吸式与气力泵清淤船清淤中余水污染物以及含水率质量浓度变化趋势，研究了2种船型清淤后对底泥界面层理结构的影响。结果表明，气力泵清淤船扰动距离、扰动强度均小于绞吸式清淤船，气力泵式清淤中淤泥含固率较高，余水量小，对底泥界面层位结构影响小。
Abstract:
Taking the pneumatic pump dredging and cutter suction dredging construction in the dredging project of Zhushan Lake in the Taihu Lake as the object, the influence of two ship types in the dredging project on the suspended solids, total phosphorus, total nitrogen, ammonia nitrogen and other indicators of the surrounding water body was analyzed, and the change trend of residual water pollutants and water content mass concentration in the dredging of cutter suction and pneumatic pump dredgers was compared and analyzed, and the influence of two types of dredging ships on the bedding structure of the sediment interface layer after dredging was studied. The results showed that the disturbance distance and intensity of the pneumatic pump dredging ship were smaller than those of the cutter suction dredging ship. The solid content of the sludge in the pneumatic pump dredging was higher, the residual water was smaller, and the impact on the interface layer structure of the sediment was smaller.
