摘　　要：采用流化态三维电极反应器处理水相2,4-二氯酚,考察了曝气强度、粒子电极密度及溶液的初始pH等因素对电解效果的影响。结果表明,以此反应器处理水相2,4-二氯酚,在表观电流密度为15 mA/cm2、曝气强度为120 m3/(h.m2)、粒子电极密度为30 g/L、pH值为4的条件下,反应120 min后,对2,4-二氯酚的去除率达到98.4%。可见,采用流化态三维电极反应器处理水相2,4-二氯酚是完全可行的。Degradation of 2,4-dichlorophenol （2,4-DCP） in aqueous solution was performed in a fluidized three-dimensional electrode reactor. The effects of operating parameters including the aeration intensity, the density of particle electrode and the initial pH values on 2,4-dichlorophenol removal were investigated. Under the conditions of apparent current density of 15 mA/cm2, aeration intensity of 120 m3/（h · m2） , density of particle electrode of 30 g/L and pH of 4, the removal rate of 2,4-diehlorophenol is 98.4% after 120 min reaction. It is concluded that it is feasible to remove 2,4-dichlorophenol （2, 4-DCP） in aqueous solution in a fluidized three-dimensional electrode reactor.
