膨润土(蒙脱石)在城市环境治理中的应用

The application of bentonite(montmorillonite) in prevention to urban environments

现代城市地质环境日益恶化,环境污染日趋严重。粘土矿物因具有特殊的层间域而具有吸附作用、离子交换作用等性质,在治理城市环境污染、净化城市空间等方面发挥着重要的作用。本文对利用膨润土(蒙脱石)在治理城市垃圾产生的渗滤液污染、修复和净化城市污染水体中的研究现状进行了综述。

The geological environment in modern cities has steadily deteriorated,and the environmental pollutions are growing serious day by day. Because there is a special interlayer region in clay minerals,there are also particular characteristics,e.g. adsorption,cation exchange,etc. Clay minerals have important applications in preventing and controlling the environmental pollutions,and in cleaning the urban environments. In this paper,the current application of bentonite(montmorillonite) is summarized in preventing and controlling refuse percolate from the modern cities,in renovating and cleaning the contaminated water in the cities.
