| 摘 要： | 该法电流效率４０％－５０％，除镉速度４０．７ｍｇ／ｍｉｎ，能耗６－１０ｋＷ·ｈ／（ｋｇ·ｄ）。处理后废水中Ｃｄ＾２＋浓度可降至１０ｐｐｍ以下，虽未能达到国家排放标准（０．１ｐｐｍ），但从镉的回收方面来看还是有效的。实验确定了处理酸性含镉废水的适宜条件，同时探讨了从废水中回收金属镉的方法。

| Abstract: | Acid Cd- containing effluent was treated with expanded graphite fluidized electrode effectively. It has advantages of fairly high current efficiency (40-50%), rapid removal of Cd2+ (40. 7mg/ min), fairly low energy consumption (6-10kWh/ kg Cd) and so on. The concentration of cadium ion in treated effluent can be decreased to below 10ppm. It does not comply with national effluent dis charge standard, but it is still effective in the recovery of cadium. Suitable conditions of treating acid Cd- containing effluent and methods for Cd-recovering were also investigated. |
