摘要：考察了多种因素对高压脉冲放电低温等离子体降解水中苯酚效果的影响。降低放电电极直径、放电距离、废水的电导率和提高废水的pH值以及向废水中通气体和加入硫酸亚铁等均可提高废水中苯酚的降解速率 ,而加入碳酸钠则会降低苯酚的降解速率。初始质量浓度为 10 0mg/L的苯酚废水经放电处理 180min后降解率达 5 0 9%。
Effects of various factors on the degradation of phenol in aqueous solution by pulsed high voltage discharge plasma were studied.Degradation rate of phenol could be raised considerably by decreasing the diameter of discharge electrode,the discharge distance between discharge electrode and grounded electrode and the conductivity of wastewater,and by increasing the pH of wastewater.Addition of FeSO 4 and bubbling of gases such as O 2 and N 2 into wastewater could also increase the degradation rate of phenol.However, addition of Na 2CO 3 to wastewater could decrease the degradation rate of phenol.After discharging for 180 min,degradation rate of 100 mg/L phenol reached 50 9%.
