| 摘 要：通過(guò)浸沒(méi)沉淀相轉化法和附加磁場(chǎng)制備了一種磁誘導復合碳納米管-四氧化三鐵（CNTs-Fe3O4）的聚砜酰胺（PSA）超濾膜，使用該膜處理橄欖油、花生油、葵花籽油、大豆油四種自制含食用油廢水。結果表明，四種自制含食用油廢水的油滴粒徑大小順序為：橄欖油>花生油>葵花籽油>大豆油，此膜對不同濃度梯度的含橄欖油、花生油、葵花籽油、大豆油廢水均可截留90.00%以上，對含花生油、葵花籽油、大豆油、橄欖油廢水通量分別為74.47、84.74、54.01、84.74 L/（m2·h），且經(jīng)四種含油廢水污染后的磁誘導復合CNTs-Fe3O4的PSA超濾膜可逆通量恢復率（FRR）分別為73.86%、71.98%、72.21%、74.35%。 |

| Abstract：A magnetically induced PSA composited CNTs-Fe3O4 ultrafiltration membrane was prepared by immersion precipitation phase transformation method and additional magnetic field. This membrane was used to treat four kinds of self-made edible oil wastewater including olive oil, peanut oil, sunflower oil and soybean oil. The results showed that the order of particle size of oil droplets in four kinds of self-made wastewater containing edible oil: olive oil>peanut oil>sunflower seed oil>soybean oil. This membrane could intercept more than 90.00% on wastewater containing olive oil, peanut oil, sunflower oil and soybean oil with different concentration gradient. The fluxes of the ultrafiltration membrane on wastewater containing peanut oil, sunflower oil, soybean oil and olive oil were 74.47, 84.74, 54.01 and 84.74 L/(m2·h), respectively. Moreover, FRR of the ultrafiltration membrane polluted by four kinds of oil-bearing wastewater was 73.86%, 71.98%, 72.21% and 74.35%, respectively. |
