摘　　要：本文进行了凤眼莲对三种不同形态银净化的静态试验研究,得出去除速率K值,24h内为K_(Ag)^+(0.136)>K_(Ag(S_2O_3))^(3-)(0.054)>K_(AgBr)(0.030)。对络合态银的净化做了动态模拟试验,揭示了凤眼莲对银的净化率R与停留时间t呈指数函数R=Ac^(B/t)(B<0)关系,表面去除负荷Ps与t呈幂函数Ps=At^B(B<0)关系。Three forms of silver (Ag+, [Ag (S2O3)2]3-, AgBr) have been selected in the static experiment of purification of silver-bearing waste water from cinefilm processing factory by water hyacinth. The results indication that silver removal rates from SBWW within 24 hours were 0. 136, 0. 054 and 0. 030 for Ag+, [Ag (S2O3)2]3- and AgBr respectively. The purification rate relate mainly with detention time(t),original silver concentration,silver form,tempera ture and pH. In addition, the results of dynamic simulated experiment with [Ag (S2O3)2]3- indicate that the relationship between purification rate (R) and detention time (t) is R=AeR/t (B<0), Relationship between surface purification rate (Ps) and detention time (t) is Ps=AtR (B<0).
