Abstract
Patent of the present invention is related to a kind of pretreatment method of refinery waste water, its effect is that refinery(waste) water is pre-processed, ultrasonication is carried out to waste water in Transverse to the flow direction, oil content, COD and the suspension of waste water is greatly reduced, it is downstream units influent quality requirement to meet, and mitigates downstream units treatment load.
Description
Technical field
The invention belongs to field of waste water treatment, combined sewage pretreating process is more particularly to refined oil.
Background technology
China is the poor country of a water resource, as the fast-developing and population of social economy is sharply increased, water money
Source shortage and environmental pollution are on the rise and have turned into undisputable fact, it is desirable to which industrial enterprise carries out reusing sewage and improves sewage row
The cry for putting standard grows to even greater heights.Meanwhile, as crude oil in poor quality and the crude resources trend of globalization increase, petroleum chemical enterprise's processing
Crude oil with poor quality is in rapid increase trend, further increases biochemical wastewater treatment difficulty, causes the reduction of biochemical treatment apparatus efficiency,
Water outlet is not even long-term up to standard, also brings bigger difficulty to reusing sewage.According to statistics, using " oil removal-flotation-biochemistry "
The petroleum chemical enterprise of " old three sets " PROCESS FOR TREATMENT oil refining sewerage, the externally discharged waste water pollutant concentration for only accounting for total release 30% can
Relatively stable reaches national grade one discharge standard, and other 70% sewage do not reach national grade one discharge standard.Therefore, some are new
Build or reorganization and expansion enterprise, sewage disposal takes shunting of removing contamination, dirty dirt to divide and rule measure, high-concentration and low-concentration waste water is respectively obtained treatment,
Overall treatment effect is preferable；Some enterprises are further added by one-level biochemistry or materializing strategy after " old three sets " technique, make effluent quality
Further improve, it is ensured that sewage stably reaching standard, also for reusing sewage creates conditions.However, being divided and ruled work using shunting of removing contamination, dirty dirt
Skill is not suitable for " long-established enterprise ", and is further added by that one-level is biochemical after " old three sets " technique or materializing strategy has that equipment investment is big, fortune
The problems such as row high cost.In addition, new technology is all distinctly claimed to water inlet index, such as oil content, COD, suspension, such as
Really these indexs are too high, cannot just ensure final process result, and the deterioration step by step of sewage quality cannot ensure that these refer to
Mark, be this just propose one how tentatively to reduce oil refining sewerage oil content, COD, indicator of suspended solids with meet subsequent technique will
The problem asked.
The content of the invention
The present invention is pre-processed using ultrasonic wave to oil refining sewerage, plays demulsification, cohesion and the Accelerated subsidence of ultrasonic wave
Effect, reduce the index such as oil content, COD, suspension of oil refining sewerage, meet subsequent treatment process requirement.
It is transported to from cistern in refinery(waste) water and supersonic generator is installed on the pipeline of downstream processing unit.Ultrasonic wave is sent out
Certain frequency that raw device Transverse to the flow direction is launched and the ultrasonic wave of intensity are so that the suspension in waste water obtains rapid subsidence
Filtered；It is smooth by isolation waste-oil scavenger below that the small oil droplet being emulsified in waste water is accumulated larger oil droplet after ultrasonic dehydration
Go out.
Treatment effect of the present invention：
Waste water oil content, COD, suspension are greatly reduced, subsequent cell treatment load is alleviated, meeting its influent quality will
Ask, improve final process effect.Meanwhile, the present invention implements simple and convenient, and equipment investment is few, it is easy to operate.
Brief description of the drawings
Accompanying drawing is process flow diagram of the invention.
Specific embodiment
The present invention is expanded on further below in conjunction with the accompanying drawings.
Refinery(waste) water enters conveyance conduit through water tank, and supersonic generator, vertical waste water water are installed at conveyance conduit A
The ultrasonic wave of stream direction transmitting certain frequency and intensity, the waste water being ultrasonically treated reaches B and removes by filtering and oil removal treatment
Equipment go out polymerization after larger oil droplet and sedimentation after suspension subsequently into next stage processing unit.
Claims (6)
