摘要
养殖水产品需求日益增高,传统水体养殖技术无法满足市场需求,由此诞生了高产低碳的循环水养殖技术,但其作为一个高密度养殖的封闭/半封闭系统对水质要求很高。循环水经处理后残余并积累的重金属污染物会给养殖系统带来安全隐患,不仅会积累于水产品体内对其造成生物毒性或直接导致其中毒死亡,还会通过食物链传递对人类健康造成威胁。如何在保持水产品的高产率下去除循环水中积累的重金属污染物是未来技术发展需要重点解决的问题。对循环水养殖系统中循环积累产生的重金属污染物的持续性危害和处理技术进行了分析和总结,预测了未来研究的突破方向,以期为去除水体重金属技术的发展提供参考。
The increasing demand for aquaculture products and the inability of traditional aquaculture technology to meet market demand have led to the birth of high yield low-carbon recirculating water aquaculture technology.How-ever,as a closed/semi-closed system for high-density aquaculture,it has high requirements on water quality.The residual and accumulated heavy metal pollutants in treated circulating water may cause potential safety hazards to the aquaculture system,which not only accumulate in aquatic products causing biotoxicity or intoxication death,but also be transmitted through the food chain,posing a threat to human health.How to remove heavy metal contami-nants accumulated in recirculating water while maintain efficient aquatic product yield is a key point for future tech-nology development.Therefore,this article analyzed and organized the sustainability hazards and treatment technolo-gies of heavy metal pollutants accumulated in circulating water aquaculture systems,and figured out breakthrough directions for future research,which expected to assist the development of heavy metal elimination technology in wa-ter bodies.
