摘要
(CN104787861B) 本​发明​公开​了​种​同时​提取​与​回收​金属元素​以及​功能​有机化合物​的​电​萃取​工艺,其​特征​在于:将​含有​功能​有机化合物​的​废水​和​金属​离子​废水​混合​后​进行​冷凝​回流​反应,使​金属​离子​与​功能​有机化合物​配位,获得​功能​有机化合物​的​金属​络合物​溶液;将​功能​有机化合物​的​金属​络合物​溶液​作为​电渗析​系统​的​浓缩​室​液​和​淡化​室​液​导入​电渗析​系统​中​进行​处理,使​淡化​室中​的​功能​有机化合物​的​金属​络合物​在​浓缩​室中​富集,去除​淡化​室中​的​功能​有机化合物​的​金属​络合物,对​浓缩​室中​的​功能​有机化合物​的​金属​络合物​进行​回收。本​发明​可以​在​处理​两种​废水​的​同时​将​金属​离子​废水​中的​金属​离子​以及​高​TOC​有机​废水​中的​功能化​合物​进行​回收​再利用,无​二次​污染,操作​简单​且​能耗​低。

(CN104787861B) 1. While extracting and recovering metal element with one of the organic compound electrical extraction process function, characterized in: The wastewater and organic compounds containing functional metal ions wastewater mixture obtained by the reaction condensation and reflux, a metal ion coordinated to form a functional organic compound with functional organic compound of the metal complex; between metal ions and organic compound coordinated function upon completion, the reaction was stopped, to obtain a functional organic compound of a metal complex solution; the functional organic compound-containing metal complex solution was cooled to room temperature; The functional organic compound of a metal complex solution as electro dialysis system in the concentrate and serves to introduce the electro dialysis system of the desalination chamber Dilute solution concentrating chamber and processed, so that the function of the metal complexes of organic compounds in the depleting compartment of the concentration chamber enrichment, the function of the metal complex of an organic compound removal-desalination chambers, to the concentrating chamber for recovering the function of the metal complex of an organic compound; Containing a functional organic compound wastewater into a wastewater acetylacetonate; of acetylacetone metal element and at the same time extraction and recovery of the extraction process comprises the steps of electrically: As metal ions with acetylacetone  1:1 molar ratio of, wastewater and wastewater after mixing acetylacetone metal ions, at a temperature of 100 Ć without larger than condensation and reflux reaction, forming a metal ion with an acetylacetonato complex acetylacetone metal complexes; between metal ions and an acetylacetonato complex was completed, the reaction was stopped, acetylacetone metal complexes obtained solution; will acetylacetone metal complexes solution was cooled to room temperature; Acetylacetone metal complex solution to 100-1000 ml/min flow rate of the desalination chamber and a concentrating compartment of the electrodialytic respectively added to the system, the electrolyte solution to 100-1000 ml/min flow rate of the anode and cathode compartments respectively added to the electrodialysis system, control electro dialysis system is a voltage of 0-100V to electrodialytic operation, acetylacetone metal complexes of the desalination chambers to migrate into the concentrating chamber, the concentrating chamber enrichment, detecting fading indoor conductivity, when it is larger than 90% salt rejection desalination chamber, out of service; The concentrated chamber acetylacetone metal complexes obtained in concentrated liquid crystal, acetylacetone metal complex crystal is obtained.
