Abstract
Waste water containing oil is passed through filter, high-pressure pump and reverse osmosis membrane pipe to realize water-oil separation. When waste water is passed through membrane, the hydrophilic and oleophylic balances of particles are destroyed, and emulsion particles are demulsified and aggregated into coarse grains to be separated. The method may be used to replace conventional chemical method, is suitable for treatment of various oil containing waste water, and has high water-oil separating efficiency.
Description
The present invention relates to a kind of method that wastewater containing oil is handled, especially adopt the reverse osmosis membrane technology method to handle wastewater containing oil.
Present conventional oil-contaminated water processing method, generally all need and the chemical agent use that cooperatively interacts, but used chemical agent is of a great variety, cost an arm and a leg, versatility is not strong, has brought many difficulties and problem for oil field sewage disposal work, the present invention is directed to existing problem, develop a kind of with physical method, the method for not using chemical agent that wastewater containing oil is handled.
The object of the invention is; the method that the wastewater containing oil of development is handled; this method with source of sewage through twice strainer; high-pressure pump; carry out oily water separation after entering reverse osmosis membrane; utilize membrane separation technique to realize that physical method is to oily water treatment; its core is according to oil in water emulsion in the sewage; dispersed oil; the character of the surface chemistry of particulate; surperficial deep layer grafting or modification at the solid-state polymer material make it have the hydrophilic of chemical demulsification performance; oleophobic or oleophylic; hydrophobic functional group; thereby make mould material have oil in water emulsion in the sewage of destruction; the function of dispersed oil microparticle surfaces; when sewage is surperficial by film; various particulates hydrophilic; oleophylic; balance is destroyed; sewage is finished the breakdown of emulsion of emulsion particle simultaneously in the film pipe is advanced; reassociate; coarse, and then reach separate stage.This method is applicable to various types of wastewater containing oils processing, easy construction, and floor space is little, and is easy to operate, and oily water separation efficient height has remarkable economic efficiency.
The method that wastewater containing oil of the present invention is handled, it is through filter, high-pressure pump, reverse osmosis membrane pipe etc. with source of sewage, with oil, water sepn, it mainly is to have adopted the reverse osmosis membrane pipe to act in wastewater containing oil is handled to destroy oil in water emulsion, dispersed oil microparticle surfaces in the sewage; The reverse osmosis membrane pipe is opened the organic polymer compound film sheet by 5-10 and is formed employing scroll-type system film forming pipe; This organic polymer compound film sheet is to be made with the aromatic polyamides of high-crosslinking-degree by polysulfone plastic.
It is as follows that the present invention adopts this method that temperature effect and stability time have been carried out its result of test: 20 ℃ 40 ℃ of temperature tests

Referring to accompanying drawing
Fig. 1 is a schema of the present invention
The method that wastewater containing oil of the present invention is processed in process chart, is by source of sewage Enter high-pressure pump, and then enter instead by gate valve through 10 μ filters, 5 μ filters by gate valve Permeable membrane namely gets and processes water and dope.
Embodiment:
At first wastewater containing oil is handled to enter and opened gate valve in the source of sewage case and filter by 10 μ strainers, 5 μ strainers; by high-pressure pump sewage is pumped into again and open the organic polymer compound film sheet by 5-10 and adopt in the reverse osmosis membrane pipe that scroll-type makes; when in the dirt by film various particulates of when surface hydrophilic, lipophilic balance is destroyed; sewage carries out in the film pipe; finish the breakdown of emulsion of emulsion particle simultaneously; reassociate, coarse, and then reach separate stage.
Claims (3)
1, a kind of method of wastewater containing oil processing, it is through filter, high-pressure pump, reverse osmosis membrane pipe etc. with the water source, with oil, water sepn, it is characterized in that, in wastewater containing oil is handled, adopt the reverse osmosis membrane pipe to act on and destroyed oil in water emulsion, dispersed oil microparticle surfaces in the sewage.
2, the method for sewage disposal according to claim 1 is characterized in that, the reverse osmosis membrane pipe is opened the organic polymer compound film sheet by 5-10 and formed employing scroll-type system film forming pipe.
3, according to right 1, the 2 described methods that contain the crude oil sewage disposal, it is characterized in that this organic polymer compound film sheet is to be made with the aromatic polyamides of high-crosslinking-degree by polysulfone plastic.
