我国除了拥有漫长的海岸线，还有众多的内河入海口，海洋和滩涂提供了十分丰富和庞大的海洋淤泥软土资源，为保证海洋航道、港口的畅通，港务部门每年都会大规模进行海洋淤泥疏浚和清淤施工，疏浚出来的淤泥大部分都海上抛弃，少部分用围海造地的方式处理。

　　In addition to China's long coastline, there are many inland river inlets. The oceans and beaches provide very rich and huge marine sludge and soft soil resources. In order to ensure the smooth flow of marine channels and ports, the port authorities carry out marine sludge dredging and desilting every year, and most of the dredged sludge is discarded at sea, A few of them are treated by reclaiming land from the sea.

　　海上抛泥淤泥中大多含有重金属和有机物，会对周边环境和海洋造成二次污染，围海造地可增加土地供给，但需经过专门处理，淤泥固化是有效的方法之一。

　　Most of the mud thrown at sea contains heavy metals and organic matter, which will cause secondary pollution to the surrounding environment and the ocean. Reclamation of land from the sea can increase the land supply, but it needs special treatment. Sludge solidification is one of the effective methods.

　　淤泥固化技术概述

　　Overview of sludge solidification technology

　　▲高含水率淤泥制作

　　▲ preparation of high moisture content sludge

　　淤泥固化土的应用不但改善了海洋环境，而且避免了清淤抛洒对海洋造成的负面影响，使传统的被动海洋清淤转变为主动的淤泥回收。

　　The application of sludge solidified soil not only improves the marine environment, but also avoids the negative impact of dredging and throwing on the ocean, and changes the traditional passive marine dredging into active sludge recovery.
