Problems solved by technology
[0010] Advantages of gravity separation method: simple structure and convenient operation; disadvantages: only oil in free state can be separated, but oil in emulsified state cannot be separated
[0024] Disadvantages of physical separation method: the oil-water separation effect is not complete, the separation takes a long time, and the equipment occupies a large area
[0025] Disadvantages of chemical separation method: easy to introduce new impurities, causing secondary pollution
[0026] Disadvantages of electric floating separation method: large power consumption and high separation cost
[0027] Disadvantages of the adsorption material method: it also absorbs water while absorbing oil, which greatly reduces the efficiency of oil-water separation, and there are also unfavorable factors such as secondary environmental pollution, recycling rate, and high price

The invention relates to a preparation method of an oil-water separation device. A copper mesh is used as a material, and a carbon black film is used as a template. A microscopic surface is constructed on the copper mesh by a chemical reaction, and then hydrophobic treatment is carried out to obtain a special invasive surface for oil-water separation. Before modification, the copper mesh is super-hydrophilic and superoleophobic. After modification, the copper mesh is super-hydrophobic and superoleophilic. Thus, different oil-water separation purposes can be achieved according to different actual situations. By different surface tension properties of water and oil, pollutants in dissolved state and emulsification state can be effectively separated. Thus, separation efficiency is greatly increased. The preparation method is simple to operate and consumes short time.
Description
technical field [0001] The invention relates to an oil-water separation device in sewage treatment technology, in particular to a preparation method of the oil-water separation device. Background technique [0002] With the continuous development of modern industrial technology, the pollution of water resources is becoming more and more serious. Faced with the increasingly difficult situation of oil-water separation, a variety of oil-water separation technologies have emerged based on different working principles and for different separation objects. [0003] The oil-water system is divided into the following states according to the state of pollutants (oil in oily wastewater or water in water-containing oil): 1. Dissolved state, water molecules exist in the molecular gaps of hydrocarbons and are homogeneous with hydrocarbons. At this time, the oil The water content in the oil is below the saturation, when the water content exceeds the saturation, the excess water will appe...
