| 摘 要： | 采用高压脉冲等离子体处理富里酸溶液,结果表明:由于等离子体的热解及氧化作用.随着脉冲电压峰值及富里酸溶液浓度的增加,溶液的pH、ORP逐渐减小,溶液的温度、浊度逐渐增加,体系中加入硝酸后能够放大等离子体作用.作为水中NOM浓度的替代参数,Uv254在等离子体作用下缓慢增加,而TDC的降解符合准一级反应规律,在35kV高压脉冲电场作用之后,TDC去除率由22.6%增至33.4%,加入硝酸后,由25.6%增至36.7%.

| Abstract: | High-voltage pulsed discharge plasma can remove natural organic matter(NOM) and produce no production of toxic by-products.Fulvic acid solution was treated by high voltage pulsed discharge plasma in this paper.It was shown that because of the thermolysis and oxidation,with the increase of peak voltage and fulvic acid solution concentration,the pH and ORP of solution decreased gradually,meanwhile the temperature and turbidity of solution increased gradually.Adding nitric acid in the treatment could amplify t... |
