This paper studied a cheap and environmental electrode with high stability and good treatment effect for phenol wastewater. It is a kind of composite-material electrode that is made of expansion graphite and attapulgite powder. The experiment investigates the stability of composite-material electrode and its ability to remove phenol. The result shows that removal rate of phenol reaches to 90% when the current density is 10 mA/cm2 ;temperature is 25 ℃ and pH is controlled at 7. After carrying on electrochemical degradation experiment for half a year ,the surface of composite-material electrode is corroded slightly. It shows that this electrode has good stability and corrosion resistance. This method reduces the cost of wastewater treatment and improves utilization rate of the electrode .
