电镀废水处理方法进展 摘要： 电镀废水中含有大量的重金属离子、无机化合物、有机化合物等有害物质，如果不进行相应的处理，将对人类健康和环境产生重大影响。

本文简述了电镀废水的来源、分类、特点、危害及处理的基本工艺。

介绍了电镀废水处理的传统方法和新方法，比较了其优缺点，举例说明了新方法的研究，并对电镀废水处理技术的未来发展趋势进行了展望。

关 键 词: 电镀废水; 处理技术; 发展趋势;重金属 Research Progress on the Treatment of Electroplating Wastewater Abstract: Electroplating wastewater contains large amounts of heavy metal ions,inorganic compounds,organic compounds and other harmful substances,if it is not treated well,human health and the environment will be affected seriously.In this paper,the origin,classification,characteristics,hazards and basic treating processes of electroplating wastewater were briefly introduced.Traditional methods and new methods for electroplating wastewater treatment were introduced,their advantages and disadvantages were compared,the study of new methods was also illustrated by examples and the future development trend of electroplating wastewater treatment technology was prospected. Keyword: electroplating wastewater; treatment technology; development trend;heavy mental. 1.前言 21世纪,随着中国成为世界制造业的中心之后,也伴随着大量的工业污染。

在各种污染源中电镀废水以其毒性大,排放量大,难治理尤其值得关注。

据不完全统计全国现有1.5万家电镀生产厂,每年排出的电镀废水约40亿m3,其中约有50%未达到国家排放标准。

并且由于电镀厂点分布广,废水中含有重金属离子、有机化合物及无机化合物等有害物质。

这些物质进入环境,必定会对生态环境及人类产生广泛而严重的危害。

电镀废水的治理是一个不可忽视的问题。

1.1电镀废水来源 电镀废水的主要来源电镀废水的主要来源是:1)电镀件清洗水。
