唐山南堡开发区排污海域沉积物中重金属含量的调查研究

Utilization of Some New Methods of Water Treatement in Shellpish Breeding

本文从唐山南堡开发区污水排海工程建设的需要出发，对排污海域沉积物中Ｃｕ，Ｐｂ，Ｃｄ，Ｈｇ，Ｚｎ和Ｃｒ６种重金属的含量及分布特征进行了调查研究，为污水排海工程的建设及开发区沿海海洋环境保护提供了基础性研究资料。

The utilization of magnetized water, foamed water, ozonized water and absorbents of heavy metallic ions in shellfish breeding was described and the usage, strong points and shortcomings were introduced in this paper so as to create a good water environment for artificial shellfish seed production and get a high and stable yield in shellfish brecding.
