金属流化床电沉积研究(Ⅰ)

Electrodeposition of Metals in Fluidized Bed

用流化床电沉积设备处理酸性含铜废水,在适当操作条件下,效率高,能耗低,治理污染和回收金属都取得令人满意的结果。(一)实验装置流化床电沉积设备的实验装置如图1所示。电解槽为高1米内径0.15米的有机玻璃管,铜粒阴极、钛钌阳极与多孔塑料隔膜松成。

A fludized cathode was employed to treat waste water containg copper in which the electrodeposit copper concentration were in 0-5kg/m^(3) range and the waste water was acidified to pH≤1.5.Superficial current densities were 280A/m^(2),while the copper was deposited about 0.12 kg per hour.Current efficiency could be over 93%,and power consumption per kilogram of copper deposited was 2.7-3.0 kW·h.It has both benefit public and economic.
