河道底泥中的重金属分析及其制砖研究

Analysis of Heavy Metal in the River Sediments and of its Brick Making Performance

实验主要分析了河道底泥中的重金属分析及制砖效果。实验以南方某城市的3条河道的底泥作为研究对象,分析了河道底泥中4类常见污染金属(Cu,Pb,Ni,Cr)的质量比及形态分布。同时实验探究了2种混掺条件下的环境影响容量底泥砖的制备与性能。实验结果表明,环境容量控制下的底泥砖具有极高的经济效益与环境效益,为有效实现底泥资源化提供了好的借鉴。

Abstract： In this paper, we mainly analyzed the heavy metal in fiver sediments and its brick making performance. We took sediments in three rivers of one city as targets and analyzed weight ratio and form distribution of four frequently polluted heavy metal （Cu,Pb,Ni,Cr）. At the same time, we studied the brick making performance of the sediments, under environmentally limited concentration, as resource by two brick making methods. The results indicated that the new brick obtained high environmental and economic benefit, which could make reference for river sediment utilization.
