摘要
人为生活生产向近岸海域排放的污染物威胁生态环境和人类健康,重金属污染的治理是环境问题的重点和难点。传统工艺存在效率低、成本高和副产品多等局限性。光催化以光为能源,是一种新兴的催化氧化和高效的清洁技术,广泛应用于水中多种污染物的处理。由于光催化在环境修复中具有优异的适应性,可用于重金属的去除。综述海洋等水体各重金属污染现状和对人类健康的影响;相对于其他处理技术,分析探究光催化技术处理海水重金属污染物的反应原理及优势;总结不同催化剂去除水体中各种重金属污染的最新进展及去除效果,并针对光催化重金属现存问题提出相应建议;以期为光催化处理海洋重金属污染的检测及风险防控提供科学指导及理论依据。
The pollutants discharged by human life and production into offshore waters threaten the ecological environment and human health.The control of heavy metal pollution is the key and difficult point of environmental problems.Traditional technology has limitations such as low efficiency,high cost and many by-products.Photocatalysis is a new catalytic oxidation and efficient clean technology and uses light as energy source,which is widely used in the treatment of various pollutants in water.Due to its excellent adaptability in environmental remediation,photocatalysis can be used in the treatment of heavy metals.The status of heavy metal pollution in marine or other water bodies and its effects on human health were systematically reviewed.Compared with other treatment technologies,the reaction principle and advantages of photocatalysis in the treatment of heavy metal pollutants in seawater were analyzed and explored.The latest progress and effect of different catalysts on the removal of heavy metals from water were summarized,and some suggestions on the existing problems of photocatalysis of heavy metals were put forward in order to provide scientific guidance and theoretical basis for the detection and risk control of marine heavy metal pollution by photocatalysis.
