活性炭的电化学再生技术研究

Regeneration of Spent Activated Carbon by Electrochemical Method

本文在测定了苯酚于椰壳活性炭上的吸附平衡和添加 2 %NaCl对吸附平衡的影响基础上 ,对用苯酚吸附饱和后的活性炭在一个搅拌槽电化学反应器中进行了再生试验研究。在室温条件下 ,通过改变再生电流的大小 ,在不同的时间间隔内 。

The regeneration of spent activated carbon saturated with phenol was conducted in the stirred electrochemical reactor under different operative conditions. The influences of operative parameters, such as regeneration current intensity and time on regeneration efficiency were systematically investigated.It was found that the electrochemical regeneration technique in the stirred electrochemical reactor is an effective method for activated carbon saturated phenol, and a much higher regeneration efficiency can be reached.
