Phenol Wastewater Treatment by High Voltage Pulse Discharge Combined with Nanometer Catalyst
摘要
Abstract
The discharge of industrial waste water is increasing year by year.We adopted high-voltage pulse discharge combine with two types of nanometer catalyst TiO2 and Fe-TiO2 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 degradation 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-TiO2 degraded phenol best;when 0.05 g Fe-TiO2 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 TiO2;the peak concentration of the other three materials will increase and then decrease faster,compared with high-voltage pulse discharge combined with TiO2,resorcinol decompose completely and the peak concentration of hydroquinone and benzoquinone decrease when treated by high voltage pulse discharge combined with Fe-TiO2;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-TiO2 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.关键词
