海上拋泥淤泥中含有重金屬我國除了擁有漫長的海岸線,還有眾多的內河入?,海洋和灘涂提供了十分豐富和龐大的海洋淤泥軟土資源,為保證海洋航道、港口的暢通,港務部門每年都會大規模進行海洋淤泥疏浚和清淤施工,疏浚出來的淤泥大部分都海上拋棄,少部分用圍海造地的方式處理。 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. 海上拋泥淤泥中大多含有重金屬和有機物,會對周邊環境和海洋造成二次污染,圍海造地可增加土地供給,但需經過專門處理,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. 淤泥固化技術概述 Overview of sludge solidification technology ▲高含水率淤泥制作 ▲ preparation of high moisture content sludge 淤泥固化土的應用不但改善了海洋環境,而且避免了清淤拋灑對海洋造成的負面影響,使傳統的被動海洋清淤轉變為主動的淤泥回收。 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. |
