乳化油废水处理技术研究进展
|
摘要
随着乳化油废水的日益增多,高效分离其中的乳化油对于环境保护与资源的有效利用颇具意义。本文综述了絮凝法、吸附法、膜分离法和磁分离法在乳化油废水处理中的研究进展与主要优缺点,并提出了今后乳化油废水处理技术的一些建议与展望。
With increasing discharge of emulsified oil wastewaters,efficient separation of emulsified oil from the wastewater is significant for environmental protection and oil resources recovery. This paper addressed the research progress of the emulsified oil wastewater treatment with various methods such as flocculation,adsorption,membrane separation and magnetic separation;moreover,the separation efficiency of various methods,as well as their advantages and disadvantages,in emulsified oil wastewater treatment were analyzed in detail. On this basis,to develop efficient and eco-friendly materials or techniques for treating emulsified oil wastewater,some effective and feasible technical proposals were prospected.
