植物对黑臭水体底泥中污染成分的吸收降解作用

Analysis of the absorption and degradation of pollutants by plants in black and smelly water sediment

系统地阐述了受污染的河道底泥对河道水体的污染机理,并在前人研究的基础上进行拓展,提出生物与物理联合修复法。抓住受污染的河道底泥中有机物含量高的特点,用底泥作为培养基质开展植生性实验。实验具有绿色环保、费用低廉的优势,实验成果为今后黑臭水体治理工作中底泥的处置问题提供了选择方向和数据支撑。

In this paper,the mechanism of polluted river sediment on river water is expounded systematically,and on the basis of previous studies,the combined biological and physical restoration method is proposed. Based on the characteristics of high content of organic matter in the sediment of polluted river channel,the experiment was carried out by using the sediment as the culture medium. The experiment has the advantages of environmental protection and low cost,and the experimental results provide the choice direction and data support for the disposal of the sediment in the treatment work of black and smelly water.
