高压脉冲放电等离子体处理含偶氮染料活性红195废水

摘要

采用高压脉冲放电等离子体处理含偶氮染料活性红195 废水,实验结果表明:当电极间距为10 mm、空气流量为0.10 m3 / h、溶液初始pH 为3.05,放电反应时间为21 min 时,活性红195 去除率为98.72%;废水中加入Cu2+时,随Cu2+加入量的增加,活性红195 的去除率先减小后增大;加入自由基抑制剂可使活性红195 去除率减小.%The wastewater containing azo-dye reactive red 195 was treated by high voltage pulsed discharge plasma. The experimental results show that: When the electrode distance is 10 mm, the air flow is 0. 10 mVh, the initial pH is 3. 05 and the reaction time is 21 min, the removal rate of reactive red 195 can reach 98. 7% ; With the addition of Cu 2+ into the wastewater, the removal rate of reactive red 195 will reduce at first and increase later; The addition of free radical inhibitor can make the reactive red 195 removal rate decreased.
