摘要
近岸海域表层沉积物中重金属污染主要包括Cu、Ni、Zn、Cr,重金属污染对生态破坏力较大,建立近岸海域表层沉积物中重金属污染检测模型,指导近岸海域表层沉积物中重金属污染处理,结合显着正相关检测方法进行污染检测模型设计,建立近岸海域表层沉积物中重金属含量分布的统计回归分析模型,采用关联分析方法进行各种重金属物质的特征分解,采用单样本非参数K-S检验方法进行分组样本检测,实现对近岸海域表层沉积物中重金属的检测和处理。
The pollution of heavy metals in the surface sediments of the coastal waters mainly includes Cu,Ni,Zn,Cr,and the heavy metal pollution is more destructive to the ecological environment.The heavy metal pollution detection model in the surface sediments of the coastal waters is established to guide the treatment of heavy metals in the surface sediments of the coastal waters,and the pollution detection model is carried out with the explicit positive correlation detection method.A statistical regression analysis model for the distribution of heavy metals in the surface sediments of the coastal waters is designed,and the characteristics of various heavy metals are decomposed by the correlation analysis method.The detection and treatment of heavy metals in the surface sediments of the coastal waters are detected and processed by the grouping sample detection method.The test results show that the method is used in this method.The accuracy of detection of heavy metals in surface sediments of coastal waters is relatively high.
