摘要：

采用自制反应器氧化降解苯酚废水,通过试验分析反应时间、pH、电解电压、Fe²⁺投加量对三维电极氧化降解苯酚废水中苯酚去除效果的影响,并确定最佳反应条件。试验结果表明,三维电极氧化降解苯酚废水有较好的去除效果,在最佳反应条件下,即反应时间为90 min,pH=3,电解电压15 V,Fe²⁺投加浓度为1 mmol/L,对苯酚质量浓度为300 mg/L的模拟废水的最大苯酚去除率达到91.2%。

Abstract:

A self-made reactor has been used for the oxidation degradation of phenol wastewater. Through experimentation,the effects of its reaction time,pH,electrolyte voltage and dosage of Fe²⁺ on the phenol removal efficiency from phenol wastewater by three-dimensional electrode oxidation degradation are analyzed. The optimum reaction conditions are determined. The results show that it has a better removal effect. The highest removal rate of simulated phenol wastewater （mass concentration is 300 mg/L） reaches 91.2%， when the optimum conditions are as follows： reaction time is 90 min,pH is 3,electrolyte voltage is 15 V,concentration of Fe²⁺ is 1 mmol/L.

Key words: three-dimensional electrode, Fenton reagent, phenol wastewater, electrochemistry
