Embodiment 1

[0051] Add 100g of quartz sand with a particle size of 0.074-0.085mm into the sand mixer and stir, then add 10g of fluorine-modified epoxy resin to the quartz sand and stir evenly to form a mixture, so that the fluorine-modified epoxy resin is mixed with the quartz sand Cover the surface with a film, then add 0.1g of silicon micropowder with a particle size of 0.015-0.020 microns, and stir evenly to make the silicon micropowder adhere to the fluorine-modified epoxy resin, then add 7g of curing agent phenalkamine and stir evenly to promote fluorine For the curing of the modified epoxy resin, add 2g of dispersant paraffin before the above-mentioned mixture is agglomerated and continue to stir to reduce adhesion. After the normal temperature curing is complete, the obtained mixture is crushed and sieved to obtain coated particles, and the coated particles are calcined at 400-600°C for 2 minutes to form a micro-nano composite structure on the surface of the coated particles to obta...

Embodiment 2

[0053] Add 100g of ceramsite with a particle size of 0.085-1.18mm to the sand mixer and stir, then add 1g of silicon-modified epoxy resin to the quartz sand and stir evenly to form a mixture, so that the silicon-modified epoxy resin is mixed with the ceramsite Surface coating, then add 0.4g of alumina powder with a particle size of 0.015-0.020 microns, and stir evenly to make the alumina powder adhere to the silicon-modified epoxy resin, then add 0.5g of curing agent cycloaliphatic amine and stir evenly , to promote the curing of silicon-modified epoxy resin, add 0.5g of dispersant calcium-based grease before the above-mentioned mixture is agglomerated and continue to stir to reduce adhesion. After the normal temperature curing is complete, the obtained mixture is crushed and sieved to obtain coated particles, and the coated particles are calcined at 400-600°C for 2 minutes to form a micro-nano composite structure on the surface of the coated particles to obtain the final produ...

Embodiment 3

[0055] Add 100g of gravel with a particle size of 0.074-0.085mm into the sand mixer and stir, then add 30g of polysulfide rubber modified epoxy resin (epoxy resin: polysulfide rubber mass ratio 5:1) to the gravel and stir evenly Form a mixture, make the polysulfide rubber modified epoxy resin film on the surface of the gravel, then add 9g of a mixture of microsilica powder and alumina powder with a particle size of 0.015-0.020 microns, and stir evenly to make the microsilica powder and alumina powder Adhere to polysulfide rubber modified epoxy resin, then add 25g curing agent aliphatic amine and stir evenly to promote the curing of polysulfide rubber modified epoxy resin, add 0.3g dispersion before the above mixture is agglomerated Add lithium-based grease and continue stirring to reduce sticking. After the normal temperature curing is complete, the obtained mixture is crushed and sieved to obtain coated particles, and the coated particles are calcined at 400-600°C for 2 minut...

Abstract

The invention discloses an oil-water separation system. The oil-water separation system comprises an oil-water separation board, an oil storage tank and a water storage tank, wherein the oil-water separation board is arranged on the top of the oil storage tank and comprises an oleophylic and hydrophobic material; the oleophylic and hydrophobic material comprises aggregates and an oleophylic and hydrophobic resin film coating the aggregates, and the oleophylic and hydrophobic resin film is formed by modified resin from one or more of fluorine, silicon and sulfur; and the side wall, away from the water storage tank, of the oil storage tank is higher than the side wall, close to the water storage tank, of the oil storage tank; and the oil-water separation board covers the top of the oil storage tank and forms an included angle with a horizontal plane. According to the oil-water separation system, as comprising the oleophylic and hydrophobic material, the oil-water separation board has oleophylic and hydrophobic performance; and when oily sewage flows through the oil-water separation board, oil seeps into the oil storage tank through the oil-water separation board, and water flows away from the oil-water separation board, thus realizing oil-water separation.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an oil-water separation system for separating oil and water in sewage. Background technique [0002] In traditional technology, there are many ways to separate oily wastewater. The commonly used oil-water treatment method is selective filtration. This method refers to the use of membrane media or hydrophilic and oleophobic media to selectively let oil molecules or water molecules pass through. Block another molecule and separate oil and water under a certain external pressure or power. The disadvantage of this method is that the wastewater needs to go through multiple cycles of repeated pressure filtration, which consumes a lot of energy. At the same time, the above medium is easily polluted after use. , so that the cost of the initial equipment and the cost of use are very high. [0003] In order to reduce costs, the simple oil-water separation device currently used in ...
