河道疏浚问题一直是我国河道整治的重要难题。为保证河道正常运行国内近年来进行了大量的河道清淤工程从而产生了大量的工程淤泥，而对于大面积的淤泥常采用修剪排泥堆场的方法集中收集淤泥使淤泥自然干化，但这种方法由于底泥与周围环境直接接触易造成二次污染，存在着较大弊端。
River dredging has always been an important problem in river regulation in China. In order to ensure the normal operation of the river, a large number of river dredging projects have been carried out in China in recent years, resulting in a large number of Engineering sludge. For a large area of sludge, the method of trimming and discharging the sludge yard is often used to collect the sludge and dry the sludge naturally. However, this method is easy to cause secondary pollution due to the direct contact between the sediment and the surrounding environment.
淤泥固化技术近年来被广泛应用于河道清淤疏浚工程中，常用的淤泥固化技术主要包括物理方法、热处理方法和化学方法。前两类由于其投资较大阳雕刻 手套生产设备 果树反光膜 北京纯水设备 保定网站制作 排水槽模具，导致应用受限，淤泥固化技术的主要原理是通过在高孔隙率的淤泥中加入固化材料，使固化材料与淤泥之间发生化学反应，最终形成胶凝结构使淤泥变为土工材料，达到资源再利用的目的。
Sludge solidification technology has been widely used in river dredging projects in recent years. The commonly used sludge solidification technology mainly includes physical methods, heat treatment methods and chemical methods. The application of the first two types is limited due to their large investment. The main principle of sludge solidification technology is to add solidified materials to the sludge with high porosity to make the chemical reaction between the solidified materials and the sludge, and finally form a cementitious structure to turn the sludge into geotechnical materials, so as to achieve the purpose of resource reuse
