生态混凝土在城市面源污染控制中的应用初探

An Application of Eco-Concrete for Urban Non-Point Source Pollution Control

生态混凝土是20世纪90年代开始研究的一种崭新的混凝土。具有独特的多孔结构。可以通过综合利用物理、化学及逐渐形成的生物膜的生物作用．清除和降解污水中的污染物，是一种理想的新型环保材料，目前主要应用于城市污水处理和科学研究。文章主要介绍了生态混凝土的特性、净水机理、应用现状及存在的问题．并提出了城市透水性路面和绿地的两种构建模式。利用生态混凝土建设城市透水性路面和绿地。从源头上控制面源污染．将是生态混凝土在城市中应用的一个新途径。

The eco-concrete has been a brand-new concrete material, and began to study in the 1990s. With the particular porous structure, eco-concrete can degrade and eliminate pollutants in wastewater through physical, chemical, and biologic processes. A detailed introduction about the characteristics of the eco-concrete, mechanism of sewage purification, its current application situation and existing problems was briefly given. Meanwhile, the urban permeable pavement and green space, two kinds of construction patterns in application of the eco-concrete to the control of urban runoff pollution were proposed.
