摘    要：文中综述了从洗相废定影液中回收银采用的物理法、化学法及生物法,分析了各种处理方法的优缺点以及废液再利用的途径。从经济、环保的角度出发,提出了采用金属置换法与活性炭吸附法联合回收废定影液中的银,更为合理、有效。

Abstract: The technologies to recover silver from the fixative wastewater,such as physical technology,chemical technology and biological technology,are introduced. The advantages and disadvantages of these technologies and the recycle approaches of the wastewater are analyzed. Moreover,the combining method of metal replacement and active carbon adsorption is more reasonable and effective,which will meet the environmental and economical requirements better.
