石化碱渣废水处理技术进展

Research Progress in Treatment Technologies for Petrochemical Alkaline Wastewater

石化碱渣废水中含有大量有毒有机物,如酚类物质和含硫有机物,不达标排放会给环境造成了严重污染。文章对石化碱渣废水的来源、危害及特点进行了简述,针对目前炼厂存在的碱渣污水处理技术进行分析论述。认为目前炼厂碱渣废水主要采用氧化处理技术和生物方法,其中催化湿式氧化处理较为常用,生物强化技术在实际中的应用日趋广泛。目前碱渣废水处理研究的趋势是开发高效,经济,环境友好,简单安全的新工艺,并要针对废水中污染物的特点结合多种方法进行治理。

Petrochemical alkaline wastewater contains many toxic and harmful organic materials, such as phenolics, organic sulfide and so on. The wastewater has very poor biodegradability and can cause great pollution to the environment. In this paper, souse, harm and characteristics of the alkaline wastewater were introduced. Catalytic wet air oxidation technology and bio-augmentation technology are common ways to treat the alkaline waste water. The recent advancement in alkaline waste treatment technology was discussed.
