摘　　要：采用自制三维电极废水净化装置,以活性炭为粒子电极,电极为片状铁电极,固定两极间距。控制电解电压、粒子电极活性炭投加量、电解时间、废水初始pH,探究在不同条件下,对邻苯二甲酸二辛酯(Dioctyl phthalate,DOP)废水净化效果,正交试验获得影响DOP废水化学需氧量(Chemical oxygen demand,COD)去除率因素主次:废水初始pH>其他因素变量>电解时间>活性炭投加量。优化方案:电解电压为36 V,活性炭投加量14 g/L,废水初始pH=4,电解时间80 min。经验证此时COD去除率为81.41%。同时也研究了影响DOP废水浊度去除率因素,在电解电压36 V、活性炭投加量10 g/L、废水初始pH 5、电解时间90 min时,DOP废水水样的浊度去除率达84.21%。In this study,a self-made three-dimensional electrode wastewater purification device is adopted.Activated carbon is used as the particle electrode,and the plate iron electrode is used to fix the distance between the two poles.Electrolytic voltage,particle electrode activated carbon dosage,electrolytic time and initial pH of wastewater were controlled to explore the purification effect of DOP(dioctyl phthalate)wastewater under different conditions.The main and secondary factors affecting the COD(chemical oxygen demand)degradation rate of DOP wastewater were obtained by orthogonal test:initial pH of wastewater>other factor variables>electrolytic time>activated carbon dosage.Optimal solution:electrolytic voltage is 36 V,activated carbon dosage is 14 g/L,initial pH of wastewater is 4,electrolytic time is 80 min.The COD degradation rate is then 81.41%.At the same time,the factors affecting the turbidity removal rate of DOP wastewater are also studied.When the electrolytic voltage is 36 V,the dosage of activated carbon is 10 g/L,the initial pH of wastewater is 5,and the electrolytic time is 90 min,the turbidity removal rate of DOP wastewater sample reaches 84.21%.
