Problems solved by technology

[0003] There are usually two principles for oil-water separation in the prior art. One is to use the difference in mass density between oil and water to separate the two through physical external force; the other is to adsorb through hydrophobic and lipophilic or oleophobic and hydrophilic materials. To separate the two, their common disadvantage is that they must go through multiple separation processes, the separation efficiency is low, and the separation is not complete.

preparation example Construction

[0039] In the present invention, the preparation method of the environment-friendly functional membrane material preferably includes the following steps:

[0040] mixing the preparation raw materials and performing plasticizing treatment to obtain a mixed material;

[0041] Extruding and granulating the mixed material to obtain pellets;

[0042] The pellets are extruded and blown to obtain an environment-friendly functional film material.

[0043] In the present invention, the preparation raw materials are preferably mixed and plasticized to obtain a mixed material. In the present invention, the mixing of the preparation raw materials is preferably carried out in a high-speed mixer; the stirring speed of the mixing is preferably 60-80 rpm. In the present invention, the temperature of the plasticizing treatment is preferably 40-60°C, more preferably 50°C; the time of the plasticizing treatment is preferably 60-120min, more preferably 90-100min. The plasticizing treatment of th...

Embodiment 1

[0058] use figure 2 The shown oil-water separation device separates the oil-water mixture and is composed of a separation chamber 1, a clean water chamber 3 and a support net 4; the separation chamber 1 is nested inside the clean water chamber 3; the separation chamber 1 Both the bottom and side walls are environmentally friendly functional membrane materials 2, and the bottom and side walls of the separation chamber 1 are covered with support nets 3; the separation chamber 1 is a closed structure with an internal pressure of 0.1 MPa; the separation The top of the chamber is provided with a feeding port 5; the periphery of the separation chamber is a clean water chamber 3, which is a closed structure; the bottom of the clean water chamber 3 is provided with a water outlet 6.

[0059] The support net is a stainless steel wire mesh, the cross section of the mesh is circular, the diameter of the mesh is 0.8 mm, and the mesh aperture of the support net is 30 mm.

Embodiment 2

[0066] Adopt the oil-water separation device of embodiment 1, according to image 3 Process flow chart for oil-water separation.

[0067] Mix 100g of pure water and 100g of edible oil to obtain an oil-water mixture; transport the oil-water mixture to the separation chamber through a sewage pump, and a metering valve is arranged on the delivery pipeline to control the delivery amount of the oil-water mixture.

[0068] After standing at 25°C for 48 hours, the water in the separation chamber is discharged into the clean water chamber, and discharged after passing the water quality test; the oil phase blocked in the separation chamber is recycled and reused.

[0069] The test results prove that the oil-water mixture can be separated by 100% by using the oil-water separation device provided by the invention.

Abstract

The invention provides an oil-water separation device and an oil-water separation method, and relates to the technical field of wastewater treatment devices. By utilizing an environment-friendly functional membrane material, a water phase can be discharged out of a separation chamber, and an oil phase is blocked in the separation chamber, so that thorough separation of oil and water is realized; and water flowing out of the separation chamber is recycled through a clear water chamber. The oil-water separation device provided by the invention is simple and easy to operate, has high oil-water separation efficiency, and can realize a 100% separation effect on an oil-water mixture.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an oil-water separation device and an oil-water separation method. Background technique [0002] Oil-water separation technology plays a vital role in people's production. For example: in industrial production, it is necessary to separate oil and water from oil-water mixtures, especially in non-ferrous smelting, catering, petrochemical and other industries; in order to protect rivers, lakes and seas from pollution, the oil-water mixture produced in the bilge machinery of ships must pass through Only after processing can it be discharged into rivers, lakes and seas. [0003] There are usually two principles for oil-water separation in the prior art. One is to use the difference in mass density between oil and water to separate the two through physical external force; the other is to adsorb through hydrophobic and lipophilic or oleophobic and hydrophilic materials.
