摘　　要：采用微电解耦合低温等离子体处理对苯二甲酸(PTA)废水,研究铁碳比、放电时间、放电电压、PTA废水初始pH值等对PTA废水净化的影响。实验表明,净化PTA废水的最优条件:微电解铁碳比为3∶1,废水pH值为6,放电反应时间为50 min,放电电压为30 kV。采用微电解1 h后,低温等离子体放电1 h,在此条件下,PTA废水COD降解率为90.87%。PTA wastewater was treated by micro electrolysis coupled low temperature plasma.The effects of Fe/C ratio,discharge time,discharge voltage and initial pH value of PTA wastewater on PTA wastewater purification were studied.The results showed that the ratio of iron to carbon in micro-electrolysis is 3∶1,the discharge reaction time is 50 min,the discharge voltage is 30 kV,and the pH value of PTA wastewater is 6.Under these conditions,the COD degradation rate of PTA wastewater is 90.87%.
