复极性三维电极-电芬顿耦合法处理苯酚废水的实验研究

Study on Treatment of Phenol Wastewater by Bipolar Three-dimensional Electrode and Electro-Fenton Method

为了降解苯酚废水中有毒有害污染物质,本研究利用复极性三维电极-电芬顿耦合法处理苯酚废水。研究通过控制p H值、进水苯酚浓度、极板间距、曝气量等影响因素对苯酚废水处理效果的影响研究得出,当p H为3、进水苯酚浓度为300 mg/L、极板间距为6 cm、曝气量为0.8 L/min时,复极性三维电极-电芬顿耦合反应器处理苯酚废水的效果最好,对苯酚的去除率可达到92.34%。

In order to degradate poisonous and harmful pollutants in phenol wastewater, bipolar three-dimensional electrode- electric Fenton method was used to treat phenol wastewater. Influence of p H value, phenol wastewater concentration, plate spacing, aeration intensity and other factors on phenol wastewater treatment effect was investigated. The best treating conditions were determined as follows： p H 3, phenol wastewater concentration 300 mg/L, the plate spacing 6 cm, aeration intensity 0.8 L/min. Under above conditions, the phenol removal rate can reach to 92.34%.
