The discharge of industrial waste water is increasing year by year. We adopted high-voltage pulse discharge combine with two types of nanometer catalyst TiO

2

and Fe-TiO

2

to degrade phenol to treat industrial waste water

investigated the degradation of the phenol affected by the catalyst calcination temperature and the additive amount

and analyzed the phenol intermediate products

the rate of mineralization

and total organic carbon（TOC）. The results show that there is a certain influence on the phenol degradatio

n rate of the calcination temperature and additive amount

with the increase of temperature and adding dosage

the Phenol degradation rate would increase and then decrease; compared with single-high voltage pulse discharge

coordination catalyst discharge can effectively improve the degradation rate of phenol

particularly treated by high-voltage pulse discharge combined with Fe-TiO

2

degraded phenol best; when 0.05 g Fe-TiO

2

catalyst is added

the calcination temperature is 450 ℃

and discharged 140 min

degradation rate of solution is as high as 98.75%; the concentration of intermediate will increase then decrease as the time changes

compared with single pulse discharge

resorcinol no longer appears continuously when treated by high-voltage pulse discharge combined with TiO

2

; the peak concentration of the other three materials will increase and then decrease faster

compared with high-voltage pulse discharge combined with TiO

2

resorcinol decompose completely and the peak concentration of hydroquinone and benzoquinone decrease when treated by high voltage pulse discharge combined with Fe-TiO

2

; the mineralization rate is increased by a big margin when a catalyst is added

compared with single high-voltage pulse discharge

when treated by high-voltage pulse discharge combined with Fe-TiO

2

for 140 min

it increases over one time. The results can provide some theoretical supports for the treatment of phenol waste by pulsed discharge synergistic catalyst.
