摘要
以中国通济桥水库环保疏浚及泥处理利用工程作为典型案例,研究在工程过程中泥的物理、化学性质变化规律,同时也分析了疏浚泥饼的力学性质。基于对泥的基本性质分析,梳理了该典型工程在疏浚、处理及利用中存在的关键问题:疏浚泥浆浓度低;泥浆浓缩效率低;疏浚与泥浆处理工效不匹配;处理后泥饼碱性高等。这些问题同样也是中国河湖库底泥疏浚、处理及利用中存在的共性问题,问题的梳理为该领域的科研及施工人员提供指导及借鉴。
With the burgeoning water environment treatment in China, a large number of environmental dredging projects are being implemented. Dredging, treatment and utilization of sediments all need to be considered. Based on the typical case of the environmental dredging, treatment and utilization project of Tongjiqiao reservoir in China, the change laws of physical and chemical properties of mud are studied, and the mechanical properties of dredged mud cake are analyzed. Through the analysis, the key problems in the typical project are pointed out: the concentration of dredged mud is low, its concentration efficiency is low, the dredging and treatment work efficiency is not matched, and the mud cake is of high alkaline property after treatment. They are also the common problems in the dredging, treatment and utilization of sediments in China. The investigation of the problems may provide guidance and inspiration for the scientific research and construction in this field.
