Abstract

Abstract:

The waste water in oil production in Liaohe Oilfield is treated by Fenton method. It is proved by using UV-Vis spectroscopy, infrared spectroscopy (FTIR) and X-ray diffraction method (XRD) that the poly ferric compounds are generated in the system. The Ferron-complexation timed spectrophotomctric method is used to confirm the species distribution of the newly-formed ferric. At the same time, the process research of Fenton's oxidation and flocculation are studied. The results show that Fenton method has a dual function of oxidation and flocculation, and both of them have synergistic effect. The dual function makes the efficiency higher than that of the separate poly ferric flocculation, and also far greater than separate oxidation of itself.

Key words: newly-formed ferric, poly ferric, Fenton reagent, oilfield wastewater

摘要：

利用Fenton法处理辽河油田采油废水时,通过紫外可见光谱法、红外光谱法(FTIR)及X射线衍射法证明了体系中有聚铁生成,并用逐时络合比色法确定了新生态铁中Fe(Ⅲ)的形态分布,同时对Fenton的氧化和絮凝作用做了分步研究,结果表明,Fenton法具有氧化和絮凝双重作用,二者具有协同效应,其功效大于单纯的聚铁絮凝,也远大于自身的单纯氧化。
