电催化氧化处理苯酚废水

Electrocatalytic Oxidation Treatment of Phenol Wastewater

采用固定尺寸的铱钌镀层钛电极作阳极、不锈钢电极作阴极、锰炭复合材料作粒子电极,利用三维电极对苯酚模拟废水进行电催化降解,并考察了电压、电解质种类及加量、反应时间等因素对降解效果的影响。得到最佳反应条件为:电压15 V、氯化钠加量2.0 g、反应时间120 min。在最佳条件下,填充10 g粒子电极的三维电极处理100 mL 10000 mg·L^-1的苯酚模拟废水,苯酚转化率为96.10%,COD降解率达83.97%。

Using a fixed-size iridium-rhodium-coated titanium electrode as an anode,a stainless steel electrode as a cathode,and a manganese-carbon composite material as a particle electrode,we performed the electrocatalytic degradation of phenol simulated wastewater by using the three-dimensional electrode,and investigated the effects of voltage,type and dosage of electrolytes,and reaction time on the degradation efficiency.The optimum reaction conditions are determined as follows:the voltage of 15 V,the sodium chloride dosage of 2.0 g,and the reaction time of 120 min.Under the optimum conditions,when 100 mL 10 000 mg·L^-1 phenol simulated wastewater is treated by the three-dimensional electrode filled with 10 g particle electrode,the phenol conversion rate will reach 96.10%,and the COD degradation rate will reach 83.97%.
