摘要
应用三相流化床电极反应器(新型电化学反应器)处理制浆废水.研究了曝气量、槽电压、溶液pH值及FeSO4浓度等因素对电解效果的影响.结果表明,该反应器深度处理制浆废水的最佳工艺条件为:槽电压20 V,曝气量为0.3 m3.h-1,FeSO4浓度为1000 mg.L-1,pH值≈2.5,反应时间为90 m in时COD去除率为70.1%.
Treatment of pulping wastewater by using a novel electrochemical reactor, i.e. the three phase fluidized bed electrode, reactor were invesigated. The effects of air flow rate, applied voltage, pH value and FeSO4 concentration on electrolysis efficiency were investigated. It was clearly shown that the 20 V of voltage, 0.3 m^3 h^-1 of air flow rate, 1000 mg L^-1 of FeSO4 concentration and pH≈2.5 were its best conditions. COD removal could be 70.1% under these conditions.
