海水养殖污染及其治理对策

The pollution of mariculture and It’s countermeasures

我国海水养殖规模越来越大,由此给海水带来了一定的污染。本文分析了海水养殖的主要污染物,包括有机质与营养盐、贵金属、抗生素等,认为其会促使养殖水域富营养化,出现毒害微生物,恶化海洋环境,最终危害人类健康;对比了物理、化学、生物学治理方式,认为采用生物学治理方式下整合浮床技术、微生物技术、藻类修复技术、植物修复技术是最有效的。

The scale of mariculture is becoming increasingly large in China,which results in certain pollution of seawater.This paper analyzes the main pollutants of mariculture,including organic matter and nutrient salts,heavy metals,antibiotics,etc.It’s believed that they will promote the entrophication of aquaculture water、toxic microorganisms、deteriorate the Marine environment,and ultimately harm human health.Comparing the physical,chemical and biological treatment methods,It’s concluded that the combination of floating bed technology,microbial technology,algal remediation technology and phytoremediation technology under the biological treatment method is the most effective.
