摘要
没有其他资源比水更为生命所需,以安全、可靠和经济的方式处理废水是21世纪最大的挑战之一。随着工业的发展,工业废水中的重金属离子因其严重的环境毒性和潜在的致癌性对环境和人类造成了巨大损害。与此同时,经过国内外许多科研工作者的共同努力,目前已发展出许多成熟或尚待成熟的技术,其可以在实际工程中有效地处理重金属废水。废水中重金属的去除主要有物理、化学、生物三种方法。本文着眼于这三个方面,介绍近年来应用于重金属废水处理领域的技术方法。
No other resource is more necessary for life than water,and treating wastewater in a safe,reliable and economical manner is one of the greatest challenges of the 21st century.With the development of industry,heavy metal ions in industrial wastewater have caused great damage to the environment and humans due to their severe environmental toxicity and potential carcinogenicity.At the same time,through the joint efforts of many scientific researchers at home and abroad,many mature or yet to be mature technologies have been developed,which can effectively treat heavy metal wastewater in actual projects.There are three main methods for removing heavy metals in wastewater:physical,chemical,and biological methods.This paper focuses on these three aspects and introduces the technical methods applied in the field of heavy metal wastewater treatment in recent years.
