【摘要】：本实验以苯酚为目标污染物,采用自制的气液两相流介质阻挡反应器对苯酚进行处理,研究了放电电压、气体流量、苯酚溶液初始浓度和初始pH对处理效果的影响,通过分析能量密度和降解动力学等因素,对反应条件进行了优化。结果表明,苯酚的去除率随放电电压、气体流量和溶液初始pH的增大而提高,随溶液初始浓度的增大而降低。在放电电压为60 kV、气体流量为60 mL/min、苯酚溶液初始浓度为100 mg/L、初始pH=10.0的条件下处理60min后,介质阻挡放电等离子体对苯酚的去除率可达60.15%,能量密度为2 404.79 J/L。
[Abstract]:In this experiment, phenol was treated with a self-made gas-liquid two-phase flow dielectric barrier reactor. The effects of discharge voltage, gas flow rate, initial concentration of phenol solution and initial pH on the treatment effect were studied. The reaction conditions were optimized by analyzing the energy density and degradation kinetics. The results show that the removal rate of phenol increases with the increase of discharge voltage, gas flow rate and initial pH of the solution, and decreases with the increase of the initial concentration of the solution. When the discharge voltage is 60 kV, the gas flow rate is 60 mL / min, the initial concentration of phenol solution is 100 mg / L, and the initial pH is 10.0, the removal rate of phenol by dielectric barrier discharge plasma can reach 60.15 and the energy density is 2 404.79 J / L.
