感潮河道生物膜吸附重金属性能及迁移规律研究
Study on Adsorption and Migration Regularity of Heavy Metals by Biofilm in Tidal River
摘要
Abstract
[Objective] The aim was to study the adsorption and migration regularity of heavy metals by biofilm in tidal rivers. [Method] By using ICP-AES method, the content of heavy metals (Mn, Zn, Cu, Pb, Ni and Cd) in biofilms (natural and artificial) , its adjacent surface sediment and river water was determined, then the absorption of heavy metals by biofilm was studied, and the migration regularity of heavy metals between biofilm and surface sediment was discussed further. [ Result ] In tidal rivers, the content of heavy metals in biofilms usually corresponded to that in nearby surface sediment; the adsorption capacity of heavy metals by biofilms showed certain limitation, which were impacted by several factors, such as biofilm characteristics, types and existing forms of heavy metals, content of heavy metals in the surface sediment, hydrological conditions and geological forms of the river, forming time of biofilm, etc. The migration of heavy metals between biofilm and surface sediment through the body of water in tidal rivers showed certain regularity, and reached dynamic balance finally. [ Conclusion] The research could provide some references for the remediation of heavy metal pollution in tidal rivers by using biofilm in the future.关键词
