Background

In recent years, with the continuous development of membrane technology, particularly the appearance of organic membranes, inorganic membranes and composite membranes, the oil-water separation membrane has more and more advantages in water treatment. The oil-water separating film first entraps particles, bacteria and other pollutant from the gas phase and liquid phase suspension, and then oil or water is used for purification, separation, concentration and other purposes. In daily life, a filter screen used for a household sink, particularly a sink in a kitchen, has no function of separating greasy dirt, so that a large amount of oily wastewater is discharged into a sewer, and flows into a river to cause serious pollution of water resources, thereby causing harm to health of human beings, animals and plants.

When the existing film filtering device is used, if larger particles exist in materials, the flowing materials carry the particles to easily break the film, so that the film is damaged, and the filtering cost is improved. When the membrane filtration device is used under different conditions, the required length is different, devices with different lengths are required to be customized, and the applicability is low. When the material on film surface piles up certain degree, the filter effect reduces, needs to change the film, but general film is fixed with the device mutually, needs to change together when changing, has improved use cost.
