| 摘 要： | 通过对油田压裂废水的系列实验,研究了H2O2预氧化对Fe/C微电解处理油田压裂废水的作用.研究结果表明,H2O2预氧化可显著促进Fe/C微电解处理工艺对压裂废水污染物的降解,提高反应效率,其主要原因在于H2O2预氧化能够降低压裂废水的粘度,提高Fe/C微电解的传质速度,并能利用Fe/C微电解反应中产生的Fe2+以激发氢氧自由基(·OH).研究还对不同浓度压裂废水进行了处理评价,结果指出H2O2/Fe/C反应体系能够有效降低压裂废水中的COD,控制其中的污染物质,该结果对于压裂废水的在实际生产中的合理处理具有指导价值.

| Abstract: | This paper mainly studied the effect of H_2O_2 preoxidation on fracturing fluid wastewater treatment by micro-electrolysis of Fe/C. The results showed that H_2O_2 preoxidation can dramatically improve the treatment efficiency of fracturing fluid wastewater by micro-electrolysis of Fe/C. The main reason is that the viscosity of fracturing fluid wastewater can be decreased by H_2O_2 preoxidation and the radical hydrogen can be excited by using Fe~(2+) which produced in the process of micro-electrolysis. The paper also studied the different concentration of fracturing fluid wastewater by the process of H_2O_2/Fe/C, and the results can guide the on-site treatment of fracturing fluid wastewater. |
