摘　　要：牡蛎壳对重金属具有良好的吸附效果。为提高人工鱼礁对重金属的吸附能力和功能性效应,本研究对比分析不同牡蛎壳配比的人工鱼礁材料对水体中Cu、Zn、Pb、Cd、Cr、As六种重金属的吸附性能,制备了一种新型功能性人工鱼礁材料,将废弃牡蛎壳作为重金属吸附材料用于海洋生态环境修复,以期实现“以废治废”的目的。结果显示,牡蛎壳颗粒掺比为50%的混凝土试块对6种重金属离子的去除率均较高;新型人工鱼礁试块对6种重金属离子的吸附趋势几乎相似,在5 min内重金属去除率均有较大幅度提升,之后上升趋势趋于平缓;新型人工鱼礁试块对重金属离子吸附能力的大小顺序是Zn>Cu>Pb>Cd>Cr>As。In order to prepare a functional artificial reef,oyster shells with different proportions were added into the experimental new artificial reef materials.The adsorption performance of the new artificial reef materials with different contents of oyster shells for Cu,Zn,Pb,Cd,Cr and As in water was investigated at different concentrations of heavy metals and different adsorption times.Oyster shell is used as heavy metal adsorption material to improve the adsorption capacity of artificial reef to repair the marine ecological environment,and fully realize the purpose of using waste to treat waste.The results showed that the concrete sample with 50% oyster shell particles has a higher removal rate of six heavy metal ions.The removal rate of the concrete sample to 6 kinds of heavy metal ions is almost similar.The removal rate increased significantly within 5min,and then the increasing trend tended to be gentle.The order of adsorption capacity of concrete samples to heavy metal ions is ZnCuPbCdCrAs.
