膜技术在含油废水中的应用及概况

Application and General Situation of the Membrane Technology in Oily Wastewater Treatment

含油废水中具有难降解的有机物,用传统的物、化以及生物方法进行处理去除效果不明显而且导致巨大的经济损失。膜处理技术具有截留能力可以有效地去除有机物而且运行费用低。但在不同因素条件下膜处理技术以及不同的膜组合工艺对有机物的去除能力不同。因此,探讨各类因素对膜处理技术的影响以及不同类型膜在实际中的应用具有实际意义,为膜处理技术广泛应用于含油废水提供依据。

Oily wastewater contains refractory organic matter, using traditional physical-chemical methods and biological treatment methods cannot effectively remove the organic matter, and can cause huge economic loss. The membrane treatment technology has intercept ability for organic matter, and can effectively remove organic matter, and its low operating cost is low. But the film processing technology and different membrane combination technology have different ability to remove organic matter under different conditions. In this paper, the influence of valious factors on the membrane treatment technology was discussed as well as practical application of different types of membranes.
