摘要
近年来,电镀、金属冶炼和制革等行业快速发展,越来越多的含Cr(Ⅵ)废水直接或间接排放到自然环境中,对生态环境和人类健康造成极大危害.因此,有必要对含铬废水处理技术进行研究.含Cr(Ⅵ)废水的处理方法包括吸附法、沉淀法、电化学法和生物法等.在查阅和分析国内外相关文献的基础上,对目前含Cr(Ⅵ)废水的处理方法进行了提炼和总结.未来,联合处理技术、新材料开发和以废治废技术将成为推动废水处理发展的重要方向.
Abstract
In recent years,industries such as electroplating,metal smelting,and tanning have developed rapidly,and more and more Cr(VI)containing wastewater is directly or indirectly discharged into the environment,causing great harm to the ecological environment and human health.Therefore,it is necessary to study the treatment technology of chromium containing wastewater.The treatment methods for wastewater containing Cr(VI)include adsorption,precipitation,electrochemical,and biological methods.On the basis of reviewing and analyzing relevant literature at home and abroad,the current treatment methods for Cr(VI)containing wastewater were refined and summarized.In the future,joint treatment technology,new material development,and waste treatment technology will become important directions to promote the development of wastewater treatment.
