臭氧氧化含油地下水实验研究

根据淄博市受石油污染的地下水的水化学类型确定单纯臭氧氧化方法，并利用现场动态实验确定臭氧化除油的最佳臭氧投加量８．０ｍｇ／Ｌ，实验表明在最佳运行状况下，臭氧化对地下水中油类物质的去除率参达到５９．０％左右。同时采用色－质联机方法，分析了臭氧化单元进出不中有机物质组分的变化，有机物种类由进水的２５种减少为出水的１７种，并有易生物降解的中间产物积累，为后续生物活性炭处理工艺提供条件。

Study on Ozone Oxidizing Groundwater Containing Petroleum Hydrocarbons

According to petroleum polluted chemical type groundwater in Zibo City, the simple ozone oxidation has been ensured, and through field situation, the optimal ozone load of oxidation unit was 8.0mg/L. Removal rate of petroleum in this unit was 59.0%, the average petroleum content in the influent reduced from 6.51mg/L to 2.67mg/L. At the sametime, adopting GS/MS method to analyze the variation of organic components in the influent and effluent, sorts of organics reduced from 25(influent) to 17(effluent), and accumulated easily degraded median product, which provided conditions for further biological activated sludge treatment process.
