Abstract
The invention belongs to water-oil separationg film Industrialized processing technique fields, more particularly to a kind of hydrophilic film material oily water separation technique, for membrane material oily water separation technique there are problems that film is easy to pollute, cleaning and regeneration is difficult, membrane flux compared with, be not able to satisfy large-scale engineering applications need, film it is poor the suitability of heterogeneity oily wastewater using a kind of film surface construct hydrophilic polymer play " bullet oil " effect and film is cross-linking modified solves the problems, such as membrane swelling and fouling membrane caused by flux decline and regeneration difficulty.
Description
Technical field
The invention belongs to water-oil separationg film Industrialized processing technique fields, and in particular to a kind of hydrophilic film material grease point
From technology.
Background technique
Currently, well known domestic and international use membrane material oily water separation technique Problems are: due to the lipophilicity of film, causing
Film is easy to pollute, cleaning and regeneration is difficult, membrane flux is lower and decaying is very fast, is not able to satisfy large-scale engineering applications needs, film is not to
The suitability of congeniality oily wastewater is poor.
Summary of the invention
The technical problems to be solved by the present invention are: being reduced using a kind of efficient hydrophilic film material oily water separation technique
Or eliminate the lipophilicity of film, reach antipollution, convenient for cleaning, membrane flux is big, length leads life, efficient function.
The present invention specifically solves the problems, such as that the scheme in above-mentioned background technique is:
A kind of efficient hydrophilic film material oily water separation technique, the technical solution: reduces or eliminates the lipophilicity of film, mentions
The hydrophily of high film, hydrophily is better, and resistance tocrocking is better；
Further, film surface constructs hydrophilic polymer or polyelectrolyte molecules brush configuration, can play " bullet oil " effect；
Further, hydrophilic membrane swelling mainly is realized to solve caused by membrane swelling and fouling membrane using cross-linking modified
The problem of flux decline and regeneration difficulty.
The beneficial effects of the present invention are:
1, the present invention uses hydrophilic film material oily water separation technique scheme, can increase substantially membrane material water-oil separating
Ability is calculated and is compared with existing lipophilic traditional membrane material oily water separation technique, and production capacity can be improved 3-5 times.
2, the present invention can be improved the effect of water-oil separating and reduce production cost.
3, the present invention has the advantages that process flow is short, high-efficient, equipment investment is small.
Attached drawing
Attached drawing is hydrophily water-oil separating schematic illustration of the invention
Appended drawing reference meaning of the present invention: 1, oily wastewater；2, oily phase；3, moisture film；4, water phase.
Specific embodiment
The invention will be further described with specific embodiment with reference to the accompanying drawing.
Hydrophilic film uses copper mesh material, to be soaked in advance before water-oil separating, enable water to the capillary canal in film
Interior generation sticks pull effect and forms liquid bridge, while forming continuous moisture film in coarse Nanosurface.
In oil water separation process, when oily wastewater 1 touches moisture film 3,3 pairs of moisture film oily phases 2 play the work of isolation mass transfer
With, the surface of film can not be touched by making oily phase 2 at all, it is even more impossible to permeate to penetrate copper mesh film, and the water phase 4 in oily wastewater 1, base
Water is transmitted continually in the effect of mass transmitting of liquid bridge, be very easy to diffusion and penetrates copper mesh film, to realize grease point
From purpose.
Claims (3)
1. a kind of hydrophilic film material oily water separation technique, it is characterised in that: use a kind of efficient hydrophilic film material, film uses
Copper mesh material.
2. a kind of hydrophilic film material oily water separation technique according to claim 1, it is characterised in that: before water-oil separating
It is soaked in advance, enables water to generate in the capillary canal of film and stick pull effect and form liquid bridge, while thick
Rough Nanosurface forms continuous moisture film.
3. a kind of hydrophilic film material oily water separation technique according to claim 1, it is characterised in that: in water-oil separating
Cheng Zhong, when oily wastewater touches moisture film, moisture film plays the role of oil mass transfer is isolated, and makes oil that can not touch film at all
Surface, it is even more impossible to permeate to penetrate copper mesh film, and the water in oily wastewater, the effect of mass transmitting based on liquid bridge pass water continually
It passs, be very easy to diffusion and penetrate nethike embrane, to realize the purpose of water-oil separating.
