Embodiment 1

[0051] Add 100g of quartz sand with a particle size of 0.074-0.085mm to 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 in the quartz sand The surface is covered with a film, and then 0.1g of fine silicon powder with a particle size of 0.015-0.020 microns is added and stirred evenly to make the fine silicon powder adhere to the fluorine-modified epoxy resin, and then 7g of curing agent phenalkamine is added and stirred evenly to promote fluorine For the curing of modified epoxy resin, add 2g of dispersant paraffin before the above-mentioned mixture agglomerates and continue to stir to reduce adhesion. After solidification at room temperature is complete, the obtained mixture is crushed and sieved to obtain coated particles. 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 partic...

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 in the ceramsite Cover the surface with a film, 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 alicyclic amine and stir evenly To promote the curing of the silicon-modified epoxy resin, add 0.5g of dispersant calcium-based grease before the above-mentioned mixture agglomerates and continue to stir to reduce adhesion. After solidification at room temperature is complete, the obtained mixture is crushed and sieved to obtain coated particles. 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 gravel with a particle size of 0.074-0.085mm to the sand mixer and stir, then add 30g polysulfide rubber modified epoxy resin (epoxy resin: polysulfide rubber mass ratio 5:1) to the gravel and mix well Form a mixture, make the polysulfide rubber modified epoxy resin film on the surface of the gravel, then add 9g of a mixture of fine silicon powder and aluminum oxide powder with a particle size of 0.015-0.020 microns, and stir evenly to make fine silicon powder and aluminum oxide powder Adhere to the polysulfide rubber modified epoxy resin, then add 25g curing agent fatty amine and stir evenly to promote the curing of the polysulfide rubber modified epoxy resin. Add 0.3g to disperse before the above mixture agglomerates Lithium-based grease continues to be stirred to reduce adhesion. After solidification at room temperature is complete, the obtained mixture is crushed and sieved to obtain coated particles. The coated particles are calcined at 400-600°C for 2 minu...

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 methods to separate oily wastewater. The commonly used oil-water treatment method is selective filtration, which refers to the use of membrane media or hydrophilic and oleophobic media to selectively allow oil or water molecules to pass through. Blocking another molecule and separating oil and water under a certain external pressure or power. The disadvantage of this method is that the waste water needs to be filtered through multiple cycles and repeated pressure, which has high energy consumption, and the above-mentioned media is easily polluted after use , Making the initial equipment cost and use cost high. [0003] In order to reduce costs, the simple oil-water separation device currently used in the industry mainly separates oil and...
