摘要:
用介质阻挡放电(DBD)产生的低温等离子体对含苯胺的废水进行了处理,研究了电极与溶液间距、输入功率、溶液初始pH值、无机阴离子(Cl-、SO24-、CO23-)和Fe2+等对苯胺降解的影响.试验结果表明,苯胺浓度为100mg/L时,电极距液面0mm苯胺处理效果最好,输入功率480W、反应10min时去除率达84.32%.苯胺降解率随输入功率和反应时间的增加而增加,弱酸和弱碱性条件下有利于苯胺的降解.NaCl、Na2SO4和Na2CO3对DBD降解苯胺有一定的协同作用,去除率最高可提高至94.52%.溶液中存在Fe2+时,可协助DBD提高对苯胺的去除,Fe2+为50mg/L时去除率最高可达98.03%
Abstract:
The nonthermal plasma technology using dielectric barrier discharge (DBD) was investigated for the treatment of aniline wastewater. The effects of the distance between electrodes and solution, input power, plasma-treatment time, different initial pH of wastewater solutions, addition of inorganic anions (Cl-、SO42-、CO32-) and Fe2+ on the decomposition were studied. The experimental results indicated that abatement of 100mg/L aniline wastewater increased with the input power. Under the same conditions, higher abatement was obtained when the distance between electrode and solution was zero mm. About 84.32%of aniline was removed after 10 min plasma-treatment time, at an input power of 480W.The initial pH had a significant impact on the removal of aniline. Weak acid and weak alkaline conditions were conducive to the aniline treatment. It was found that the extent of degradation increased with the addition of certain NaCl、Na2SO4、Na2CO3 and Fe2+. The removal of aniline could be increased to 94.52% while 50mg/L NaCl (calculated by the concentration of Na+) was added to the solution. About 99.72%of aniline was removed after 10min plasma-treatment time with concentration of 50mg/L initial Fe2+
