【摘要】 本文提出了用乳化液膜处理含氰废水的方法,研究了不同浓度氰化物废水的液膜萃取速率,讨论了添加剂对除氰的影响。间歇和连续逆流革取试验的结果表明:液膜法除氰效率高,并能回收氰化物,因此是一种理想的氰化物污水处理新技术。更多还原

【Abstract】 The treatment of cyanide with emulsion liquid membrane is presented in this paper, in which not only the extraction rates of cyanide with different concentrations are studied, but the effect of an addifive on extraction is dis- cussed as well. The results from the experiments of both batch extraction and counter-current confact extraction showed that the removal etticiency of cyanide with emulsion liguid membrane is guite high and the cyanide could be recoveried, hence it is a good method for treating the wastewater contai ning cyanide更多还原
