摘　　要：采用GC-MS分析测定了某石油树脂生产企业的废水原水及经铁碳微电解、铁碳微电解-H_(2)O_(2)、O_(3)/H_(2)O_(2)、O_(3)/H_(2)O_(2)-铁碳微电解等4种工艺预处理后的出水中主要的有机成分。结果显示,废水经预处理后,主要有机物从有机硫化合物、脂肪烃类、含苯基的酯类等转化成醇类、酮类、萜类、含氧烃和有机含氮化合物等较小分子物质。对比4种工艺出水中有机物组成及其他污染指标分析结果可知,O3/H_(2)O_(2)-铁碳微电解工艺综合了其余3种工艺的优点,适用于处理碱性石油树脂废水。GC-MS was used for the characterization of organic materials in petroleum resin production wastewater which collected from a petroleum resin production enterprise and the effluent water pretreated by iron carbon micro-electrolysis,iron carbon microelectrolysis-H_(2)O_(2),O_(3)/H_(2)O_(2) and O_(3)/H_(2)O_(2)-iron carbon microelectrolysis.The results showed that,through the pretreatment,the main organic pollutants in the wastewater were transformed from organic sulfur compounds,aliphatic hydrocarbons,ester compounds that contains phenyl groups etc.into small molecules substances such as alcohols,ketones,terpenoids,oxygenated hydrocarbons,organic nitrogen-containing compounds and so on.Comparing the analysis of the organic composition and other pollution indicators in the effluent water discharged from the above four processes,the results showed that,O3/H_(2)O_(2)-iron carbon microelectrolysis combined the advantages of the other three processes,which was suitable for alkaline petroleum resin wastewater treatment.
