流态化电极电解法处理含氰废水

Treatment of CN￣-Containing Wastewater by Electrolysis With Fluidized Electrode

采用细粒膨胀石墨流态化阳极电解法处理含氰量为８０－９０ｍｇ／Ｌ从的废水，试验选择出的处理条件为：ｐＨ９－１０、废水流速４２－４５Ｌ／ｈ、槽电流２－３Ａ，ＮａＣｌ加入量１．５－３．０ｇ／Ｌ．同样条件下，使用细粒膨胀石墨流态化电极的电解除氰效果较用筒形板状电极好。

The wastewater containing CN￣- of 80-90mg/L was treated by electrolvsis withfluidized anode made of fine grain expanded graphite. The treatment conditions definedby experiments were as follows:pH 9-10, wastewater flow rate 42-45L/h,cell current2-3A, NaCl added l.5-3.0g/L. Under similar circumstances,CN￣-emoval efficiencywith fluidized electrode made of fine grain expanded graphite was better than that withtubular plate electrode.
