摘要
工业废水中含有大量重金属,对人类健康、水生生物和生态系统有害。本综述的重点是评估废水的来源和处理方法,重点是技术、优缺点和创新。传统的废水处理方法已显示出良好效果,但也存在一定的局限性,例如产生大量污泥、去除率相对较低等。纳米技术、光催化和电化学混凝等新技术比传统的重金属去除方法具有显著优势,包括更高的去除率、更高的能源效率以及对特定污染物的更大选择性。然而,与这些先进方法相关的高成本仍然是这些技术的主要缺点。因此,我们建议废水处理技术的未来发展重点是降低成本和减少废物产生。
Industrial wastewater contains a large amount of heavy metals,which are harmful to human health,aquatic organisms,and ecosystems.The focus of this review is to evaluate the sources and treatment methods of wastewater,with a focus on technology,advantages,disadvantages,and innovations.Traditional wastewater treatment methods have shown good results,but also have certain limitations,such as generating a large amount of sludge,relatively low removal rates and so on.The new technologies such as nanotechnology,photocatalysis,and electrochemical coagulation have significant advantages over traditional heavy metal removal methods,including higher removal rates,higher energy efficiency,and greater selectivity for specific pollutants.However,the high cost associated with these advanced methods remains a major drawback.Therefore,we suggest that the future development focus of wastewater treatment technology should be on reducing costs and waste generation.
