Abstract:

Metal ions have been one of the main pollutive sources. The treatment methods, such as chemical precipitation, ion exchange, adsorption, biological treatment, and membrane separation for treating wastewater with low concentrated metal ions are summarized. The advantages and disadvantages of various methods are compared comprehensively. It is pointed out that using ion exchange for treating wastewater with low concentrated mental ions is prone to realizing industrialization and automation,which is the trend of the future development. The synthetic of high performance chelating resin and the study of ion exchange equipment will be two research topics in the future. At the end, the current problems and the research direction of future development are prospected.

Key words: wastewater with low concentrated metal ions, chemical precipitation; ion exchange, adsorption, membrane separation
