铜银离子化水消毒技术的发展及应用

Development and application of copper-silver ionization in water disinfections

介绍了铜银离子化水消毒技术的历史和发展及其在水处理工业上的应用。铜银离子化水消毒技术就是用电解的方法产生铜银离子用于水消毒。科学研究发现并证明铜银离子和氯等消毒剂具有协同消毒作用。铜银离子结合其它低浓度消毒剂可以有效控制肺炎军团菌等致病微生物,并具有低浓度有效、作用速度快、可长时间维持残留浓度、消毒副产物少、毒性低等优点。英美等国家已经制定了有关铜银离子化的技术标准,并广泛用在游泳池、建筑物热水系统等公共用水工程上。

This article illustrated the history and development of copper-silver ionization as well as its applications in the water treatment industry. Copper-silver ionization is the term given to the electrolytic generation of copper and silver ions for use in water treatment. Studies have shown the synergetic effects existing between copper-silver ions and other chemical disinfectants. Combined with other disinfectants in low concentration, the electrolytic generated copper-silver ions can control waterborne pathogensas Legionella, etc., and have a number of advantages over individual substances in fast inactivation, reduced dosage, long lasting residual effects, low disinfecting byproduct and low toxicity of its components. Standards and technical guidelines have already been set up for the application of copper-silver ionization in water treatment in USA and other European countries.
