摘要
在自然界中,重金属易在冶金、采矿、化工、制革、纺织等工业废水中积聚并造成环境污染.重金属具有难降解、易富集、毒害大以及隐蔽性等特点.汞、镉、铬、铅、砷、镍等重金属在水中的存在会对人类生存和健康以及自然环境保护构成严重威胁.基于此,文章对重金属污染废水的来源、危害性、治理现状及其在处理中的研究进展与治理方法展开了综合分析,并揭示了不同处理方式的治理原理和作用效果.
Abstract
In nature,heavy metals are easy to exist in industrial wastewater of metallurgy,mining,chemical industry,tannery,textile and cause environmental pollution.Refractory to degradation,easy to enrich,highly toxic,and concealment are the prominent characteristics of heavy metals.Heavy metals,such as mercury,cadmium,chromium,lead,arsenic and nickel,can pose risks to the natural environment and human survival and health.Based on this,the paper comprehensively analyzes the sources,harmfulness,treatment status,research progress and treatment methods of heavy metal polluted wastewater,and reveals the treatment principles and effects of various treatment methods.
