电弧放电等离子体处理苯酚废水的研究

Research Progress on Advanced Oxidation Technology of Ammonia Nitrogen Wastewater

含苯酚废水有毒、难降解,其排放给周边环境带来了严重的污染。本文采用电弧放电等离子体对苯酚进行了处理。通过实验考察了污染物浓度、电压、反应时间和溶液pH值对对苯酚去除的影响。实验结果表明:浓度为100 mg/L,电压为8 kV,放电处理时间为5 min,pH 2~4之间时,苯酚的降解率达到最大。研究结果为工业废水的处理提供了参考。

Phenol wastewater is toxic and difficult to be degraded,which brings serious pollution to the surrounding environment.Phenol was treated by arc discharge plasma.The effects of pollutant concentration,voltage,reaction time and pH value on phenol removal were investigated.The results showed that the degradation rate of phenol reached the maximum when the concentration was 100 mg/L,the voltage was 8 kV,the discharge time was 5 min,and pH was between 2 and 4.The study was proposed to provide technical guidance for their future industrial development.
