摘要
对所选定的活性炭 ,吸附苯酚饱和后进行电化学再生。在室温条件下 ,选择 4因素、2水平的正交试验方法进行了相关试验。结果表明 ,再生位置是活性炭再生工艺中最重要的影响因素 ,电解质NaCl浓度是较重要的影响因素 ,再生电流和再生时间对活性炭的电化学再生有一定的影响。
Electrochemical regeneration of activated carbon adsorbed with phenol was investigated in different operative conditions.The effects of several operative parameters on electrochemical regeneration efficiency were measured in room temperature by means of orthogonal experimental method.The experimental results show that it is the key factor to put activated carbon on the cathode not the anode,and other main factors of effecting regeneration efficiency are as follows:the regeneration current intensity is 30mA,regeneration time is 5 hours,electrolyte(NaCl)concentration is 2%.
