Filtering method.
Background technology
With the variation of oil reservoir development mode, the continuous application of oil recovery new technology, the continuous improvement of recovery percent of reserves is caused
Produced Liquid is become increasingly complex, and recovered water is more and more, and intractability is increased, conventional sewage " two-stage oil removing+double-filtration " technique
Flow adaptability need to be improved further.
For current oily waste water treatment flow, filter plant is the key equipment in sewage disposal, is sewage disposal
Last pass, at present based on pressure filter tank, conventional filter has walnut shell filter, Double-filter material filter, is situated between more
Mass filter, silicon carbide filter etc., but these filter effluent qualities are unable to stably reaching standard, and filter inflow requirement is high,
Easily dirty stifled, the backwash and regeneration effect of filtering material is poor, and contamination resistance is poor, and filter material replacement is frequent, a whole set of processing system held stationary
Trouble-free operation difficulty is larger.
Graphene is a kind of two-dimentional carbon material of monoatomic layer, and hexagonal honeycomb structure possesses strong absorption property, superelevation
The characteristics such as electron mobility, high mechanical properties and high-specific surface area.Based on the performance that graphene is excellent, can have it by modification
There is hydrophilic and oleophobic characteristic, modified graphene is combined using special process with nethike embrane base material, the wetting on membrane material surface can be changed
Property, the water-oil separating performance of membrane material is effectively improved, water can be quickly through crude oil and SS are then not easily passed through.Stone
Black alkene film is in field extensive uses such as municipal wastewater processing, river course water process, chemical plant sewage disposals.
At present, the technology is still in exploratory stage, the oil resistant of graphene film in the application study of field of oilfield sewage treatment
Further checking is needed in terms of performance, anti-fouling performance and influent quality requirement, to realize the technology in oil-contaminated water of oil field
Popularization and application in processing.
The content of the invention
It is an object of the invention to：For the defect present in existing filtering oily sewage technology, a kind of resistant is explored
Dye ability is strong, influent quality requires wide in range, can be well adapted for oilfield sewage operating mode, the simple stone of matched processing technology flow
Black alkene membrane filtering method.
This technique is particularly suitable for use in oil content≤100mg/L, suspension content≤50mg/L oily waste water treatment.
The new technical scheme of the present invention is：A kind of graphene film filter method for oily waste water treatment, described step
Suddenly it is：
Oil-polluted water is delivered to graphene-based nethike embrane by about 50 DEG C of oil-polluted water water after water header tank by elevator pump
Filter, pressure 0.05MPa~0.3MPa of elevator pump；
Dosing mouth is set in graphene-based nethike embrane filter back with water inlet line, demulsifier is added by chemicals dosing plant, makes oil in water
It is middle that complete free state is presented；Oil-polluted water is filtered by graphene-based nethike embrane filter, and output water is by delivery port by carrying
Rise pump and be delivered to production water header tank；
Graphene-based supporting positive flushing and the backwash facility of nethike embrane filter, using water after filter, dosing mouth is set on pipeline, is led to
Cross chemicals dosing plant and add cleaning agent, the sewage after flushing enters backwash and reclaims water pot.
Water water pipe is provided with sample point, and oil-polluted water water inlet is oil content≤100mg/L, suspension content≤50mg/
L；Produce water header tank and be provided with sample point, oil-polluted water water outlet is oil content≤15mg/L, suspension content≤5mg/L.
The processing method of the present invention is uses graphene film, and it has good hydrophilic and oleophobic performance, high mechanical strength, resistant
The characteristics of dye, acidproof alkali cleaning, and milipore filter is carried out pickling and alkali cleaning after the pollution such as greasy dirt, suspension, can obtain preferably
Regeneration, recovers good water penetration.Oil content of wastewater≤9.3mg/L, suspension content≤4.6mg/L, suspension after processing
Median particle size≤2.1 μm, meet《Clastic rock reservoir water water quality fertilizer index and analysis method》In SY/T 5329-2012
Three-level water quality requirement：Oil content≤15.0mg/L, suspension content≤5.0mg/L, suspension median particle size≤3.0 μm, can be with
Meet oil-field flooding water quality requirement.
