The invention discloses a kind of biological reinforced processing unit of oily wastewater, device is designed to pot type, is divided into air-dissolving air-float area and microbial reaction area Liang Ge functional areas.Air-dissolving air-float area is located at the central tube of tank.Including water inlet, water distributor, dissolved air release.Air flotation zone effect is to remove oil slick most of in sewage by molten gas mixing water.Microbial reaction area includes microbe stuffing region, aerated portion.Effect is that the channel of air flotation zone middle and upper part from top to bottom enters microbial reaction area, and under the action of microorganism, oil emulsion detaches removal after being demulsified, and water flows automatically after the collection of lower part collector pipe after processing enters downstream processing unit；The crude oil of collection enters oil storage tank by collection tank through flowline；Sludge is periodically discharged into recycling pond in station through sludge pipe.The problem of present invention can effectively solve the problem that the complicated oily wastewater sedimentation time is elongated, and processing capacity declines.
Description
Technical field
The present invention relates to sewage treatment fields, and in particular to a kind of biological reinforced processing unit of oily wastewater.
Background technology
With putting more effort for tertiary oil production in oil field exploitation, the development modes such as high concentration, ternary composite driving cause current original
Water water-quality constituents is complicated and is difficult to handle, and water drive is higher and higher containing poly- concentration, and oil field oil-containing dirt is given in the variation of this raw water quality
Water treatment system causes huge impact.It is mainly manifested in：1st, the sedimentation time extends, popularization：Tertiary oil recovery exploitation
After containing the chemical substances such as polymer, surfactant in recovered water, aqueous viscosity increases, and oil-water emulsion is serious, leads to water-oil separating
Time lengthening.The sewage sedimentation time by 6 hours of water drive increase to ternary composite driving 18 hours, sinks when sewage plant designs at present
The extension of drop time, which directly results in sewage plant sedimentation tank volume, to be increased, and floor space increases.2nd, filtering velocity declines, and filter tank quantity increases
Add：The filtering tank filtering velocity design parameter of oily waste water treatment experienced after water drive to poly- drive raw water quality constantly variation,
It is driven from early stage pure water（16/8）M/h is gradually shown in after gathering to the nineties later stage raw water and is adjusted to（12/8）M/h 2005 is
Preferably ensure water quality, reduce the injury to stratum, filtering velocity is adjusted to again（10/6）M/h considers to see in raw water for 2008
Poly- concentration is likely to be breached 350 mg/L, and to ensure effluent quality, design filtering velocity is reduced to again（8/4）M/h, to 2009 due to
Filtering velocity reduces the problems such as occupation of land brought is big, construction investment is high, and design filter tank is restored to（12/8）M/h, but construction scale considers
20% water more than needed, the ternary sewage plant of tertiary oil recovery and the design filtering velocity at high-concentration sewage station are（7/5）m/h.Design filter
The reduction of speed causes filter tank quantity in sewage plant to increase, and occupation of land is big, investment is high, while operating cost is high.
In order to cope with the situation of water degradation, need to develop a kind of new technical matters, the solution sedimentation time is elongated, filtering
Slow, processing capacity decline the problem of.
Invention content
It is transformed in view of the structure of settling tank convenient for old station, the present apparatus is designed to pot type, is divided into air-dissolving air-float area and micro- life
Two functional areas of object reaction zone.Air-dissolving air-float area is located at the central tube of tank.Including water inlet, water distributor, dissolved air release.Air supporting
Area's effect is to remove oil slick most of in sewage by molten gas mixing water.Microbial reaction area include microbe stuffing region,
Aerated portion.Effect is that the channel of air flotation zone middle and upper part from top to bottom enters bio-reaction zone, under the action of microorganism, emulsification
Oil detaches removal after being demulsified, and water flows automatically after the collection of lower part collector pipe after processing enters downstream processing unit；The crude oil of collection
Enter oil storage tank through flowline by collection tank；Sludge is periodically discharged into recycling pond in station through sludge pipe.
Description of the drawings
Attached drawing 1 is the structure diagram of the present invention；
In figure：1st, tank body 2, water distribution pipe 3, molten gas liberation port 4, collection tank 5, water outlet regulating tank 6, rotary-cutting type aeration head 7,
Inclined plate sedimentation case 8, water outlet inlet 9, mud-collecting slot 10, observation panel 11, light-transmitting opening 12, anti-explosion exhaust mouth 13, air dissolved pump water inlet pipe
14th, overflow pipe 15, water outlet exhaust outlet 16, water outlet newel 17, heat traced pipeline.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings：
The pot type oily wastewater biochemical treatment apparatus.What it was realized in：Water enters middle and upper part water distributor 2 by water inlet pipe
Start water distribution.It is dissolved air release 3 below water distributor, the water outlet of release 3 is to be drawn by reflux pump by reflux pump water inlet pipe 13
The water handled in tank enters air-dissolving apparatus, and the dissolved air water of generation releases the dissolved air water of micro-bubble, molten gas by release 3
Oil slick and particulate contamination during band is leaked water during bubble in water floats up enter collection tank 4, are connected by collection tank 4
Delivery pipeline discharge outside the tank.Water inlet distributor 2 and release 3 are placed in pipe in the central tube at center, form air flotation zone
Domain.The biologic packing material area of two layers of steel framework composition is with outside central tube.Biologic packing material can be combined fiber filler, three-dimensional bullet
Property filler, soft or semi soft packing.Gas from roots blower is by air line, the exposure being transmitted to below filler region
It on gas coil pipe, is discharged into water body by gas release device 6, the microorganism to be attached in tank body on filler region provides growth institute
The dissolved oxygen needed.Water moves across the microbial reaction removal oil emulsion being attached in filler body and dissolved oil down；After processing
Water enter tilting box 7 below aeration coil pipe, which there is inclined plate packing in the inside of tilting box 7, plays sedimentation and removes oil removal.
Treated the water of collector pipe 8 is connected above 7 inclined plate packing of tilting box pass through tilting box 7 and enter collector pipe 8.It and will by newel
Water is delivered to water outlet Adjustable water tank 5 and discharges.Newel has exhaust outlet 15 in upper end, play adjust newel water flow pressure with
Outer air pressure balance.
Tank structure is vertical settling tank used by the pot type oily wastewater biochemical treatment apparatus（Natural subsidence tank or
Coagulating setting tank）Tank body, original heat traced pipeline 17, collection mud pit 9, tank top observation panel 10, light-transmitting opening 11, exhaust outlet 12 in tank
Etc. structures it is constant.Aerating gas amount is set after being calculated according to the water quality condition of sewage.
Present treatment device has following characteristics：
1st, the device of the invention has sedimentation, air supporting and microbiological treatment triple functions, can effectively go the suspension in water removal
Object, oil slick and oil emulsion, improve treatment effeciency.
2nd, using pot type structure, there is very high versatility with existing system, be conducive to transformation and upgrade of standing always.Using this
When technique carries out old station transformation, existing equipment can be made full use of, reduce the quantity of newly-built equipment, reduce to greatest extent operation into
This.
