摘要
用自制金属氧化物粒子电极在三维电极反应器中降解酚类,试验分析曝气流量、进水pH、电解电压、粒子电极填充量及反应时间对三维电极氧化降解炼油废水中酚类去除效果的影响,得出最佳反应条件:曝气流量为0.5 L/min,不调节进水pH 6.5,电解电压12 V,粒子电极投加量为100 g,反应时间为60 min,在此条件下对酚类浓度为15～20 mg/L炼油废水的最大酚类去除率达97.54%,COD的去除率为81.59%。
The refinery wastewater was experimentally investigated using a three - dimensional electrode reactor（TDER）with metal composite oxide as particle electrode. The effects of operating parameters such as airflow, pH value, cell voltage, particle dosage and electrolysis time on the removal efficiency of phenolic compounds were studied. The optimal experimental condition were obtained as follows： airflow was 0.5 L/min, pH value was 6.5, cell voltage was 12 V, amount of particle electrode added was 100 g, wastewater treatment time was 60 minutes. The removal efficiencies of phenolic, COD compounds were 97. 54%, 81.59% respectively for refinery wastewater containing 15 - 20 mg/L phenolic compound.
