摘　　要：介绍了利用滑动弧放电对印染废水甲基紫进行降解的实验,主要对比了不同气流量、不同载气以及放置不同时间下降解液的COD值,一般来讲,在气流量为0.3 m3/h时,经过三次降解后溶液的COD值已能达到排放标准,四次降解的溶液COD值几乎为零,最后探讨了催化剂(Fe2+)的加入对降解的影响,发现催化剂Fe2+对放置后样品的自行分解有抑制作用,在实际应用过程中不提倡使用。Methyl violet was treated with a new method that can deal with organic wastewater by gas-liquid two phase gliding arc plasma. Several factors impacting the degradation were studied, including the gas feed rate, the type of gas and the variation of COD of wastewater with different standing time. The results showed, in generally, when the gas feed rate was 0.3 m^3/h, the value of COD which is of the third time degradation of Methyl violet could measure up to the emission standard, and the valuation of the fourth time degradation was almost zero. Also, the affection of catalyst ＂Fe^2＋＂ was discussed, which inhibited the self-degradation of the wastewater and was not encouraged to use in practical application.
