高级氧化技术应急处理炼化企业水体污染物的研究

RESEARCH ON EMERGENCY TREATMENT OF REFINING WATER POLLUTION BY ADVANCED OXIDATION TECHNOLOGY

炼化企业在突发事故中产生的高浓度难降解废水对环境的危害较大,这类污染物具有排放浓度高、污染面广、生物毒性大的特点。该类废水用常规的生物处理技术难以奏效。近年来高级氧化技术处理废水具有氧化性强、反应时间短、见效快等优点。介绍了几种高级氧化技术的基本原理及在废水处理中的研究进展,分析比较了各自的优缺点,探讨了它们在应急处理中应用的可行性。

Wastewater with high concentration which is hardly degradable produced from sudden accidents in petrochemical enterprises does more harm to the environment. Such pollution has the characteristics of high concentration of pollutant emissions,wide pollution area and high biological toxicity. The conventional biological treatment technology doesn't work for such kind of wastewater. Recently advanced oxidation technology has the advantages of strong oxidation,short reaction time and quick results in treating wastewater. This paper introduces the basic principles of several advanced oxidation technologies and their research progress in wastewater treatment. It analyzes and compares the advantages and disadvantages of these technologies. The paper also discusses the feasibility of the application of several advanced oxidation technologies in emergency treatment.
