Abstract

본 발명은 유화된 오일폐수의 농축방법에 관한 것으로서, 더욱 상세하게는 유화된 오일폐수를 한외여과막을 사용하여 농축하는 과정에서 발생되는 유리오일을 계면활성제를 첨가하여 유화시켜 투과성능을 유지시킴으로써 농축효율을 높이고 막성능을 최대한 발휘시킬 수 있는 오일폐수의 농축방법에 관한 것이다.The present invention relates to a method for concentrating an emulsified oil wastewater, and more particularly, to concentrate emulsified glass oil generated by the process of condensing emulsified oil wastewater using an ultrafiltration membrane by adding a surfactant to maintain permeability. The present invention relates to a method for concentrating oil wastewater, which can increase efficiency and exhibit maximum membrane performance.

Claims (4)

수분산된 유화오일농도가 1% 이상인 오일폐수를 한외여과막을 사용하여 농축함에 있어서, 오일폐수에 계면활성제를 첨가하여 농축과정에서 발생하는 유리오일을 유화시키면서 농축시키는 것을 특징으로 하는 유화된 오일폐수의 농축방법.In concentrating oil wastewater having a concentration of 1% or more of the dispersed oil emulsion using an ultrafiltration membrane, a surfactant is added to the oil wastewater to concentrate emulsifying the free oil generated during the concentration process. Method of concentration. 제1항에 있어서, 상기 계면활성제는 오일폐수에 대하여 0.01~5중량% 사용함을 특징으로 하는 유화된 오일폐수의 농축방법.The method of claim 1, wherein the surfactant is used in an amount of 0.01 to 5 wt% based on the oil wastewater. 제1항에 있어서, 상기 계면활성제로는 음이온성 계면활성제, 양이온성 계면활성제, 양성 계면활성제 또는 비이온성 계면활성제를 사용하는 것을 특징으로 하는 유화된 오일폐수의 농축방법.The method of claim 1, wherein the surfactant is an anionic surfactant, a cationic surfactant, an amphoteric surfactant, or a nonionic surfactant. 제1항에 있어서, 상기 계면활성제 첨가전에 1차적으로 협잡물질 및 오일물질을 기계적 방법으로 제거하는 것을 특징으로 하는 유화된 오일폐수의 농축방법.The method of claim 1, wherein the contaminants and oils are first removed by mechanical methods prior to the addition of the surfactant. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
