吸附法是废水处理工艺中常用的方法,主要介绍了改性生物类吸附剂、改性矿物类吸附剂和改性工业废物类吸附剂对废水中六价铬离子的吸附处理,并对它们的未来发展进行了展望。三种改性吸附剂的原料大部分来源于自然,价格低廉,比表面积大,可以有效处理废水中的铬离子。
Adsorption method is common method in wastewater treatment process.Three kinds of modified adsorbents,including modified biological adsorbent,modified mineral adsorbent and modified industrial waste adsorbent,were introduced for the adsorption treatment of hexavalent chromium ion(Cr6+) in wastewater.Most of these modified adsorbents were from natural sources,with low price and large specific surface area,which can effectively treat Cr ions in wastewater.The future treatment of Cr ions in industrial wastewater was prospected.
