Description

A kind of biological reinforced processing unit of oil-polluted water

Technical field

The utility model is related to sewage treatment area, and in particular to a kind of biological reinforced processing unit of oil-polluted water.

Background technology

With putting more effort that tertiary oil production in oil field is developed, the development mode such as high concentration, ternary composite driving causes current original Water water-quality constituents is complicated and is difficult to handle, and water drive contains poly- concentration more and more higher, and the change of this raw water quality is dirty to oil field oil-containing Water treatment system causes huge impact.It is mainly manifested in：1st, the sedimentation time extends, popularization：Tertiary oil recovery exploitation Contain in recovered water after the chemical substances such as polymer, surfactant, aqueous viscosity increase, oil-water emulsion is serious, causes water-oil separating Time lengthening.The sewage sedimentation time increased to 18 hours of ternary composite driving by 6 hours of water drive during current sewage plant design, sank The extension of drop time directly results in sewage plant sedimentation tank volume increase, and floor space is increased.2nd, filtering velocity declines, and filter tank quantity increases Plus：The filtering tank filtering velocity design parameter of oily waste water treatment, after it experienced from water drive to poly- drive raw water quality constantly change, Driven from early stage pure water（16/8）M/h, is progressively shown in after gathering to the nineties later stage raw water and is adjusted to（12/8）M/h, be within 2005 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 returned to（12/8）M/h, but construction scale consideration 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 increase in sewage plant, and occupation of land is big, investment is high, while operating cost is high.

In order to tackle the situation of water degradation, it is necessary to develop a kind of new technical matters, the solution sedimentation time is elongated, filtering Slow, the problem of disposal ability declines.

Utility model content

Structure in view of settling tank is easy to old station transformation, and the present apparatus is designed to pot type, is divided into air-dissolving air-float area and micro- life Two functional areas of thing 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 most of oil slick in sewage by molten gas mixing water.Microbial reaction area include microbe stuffing region, Aerated portion.Effect is that the passage of air flotation zone middle and upper part from top to bottom enters bio-reaction zone, in the presence of microorganism, emulsification Oil is separated after being demulsified and removed, and gravity flow enters downstream processing unit after water is collected through bottom collector pipe after processing；The crude oil of collection Enter oil storage tank through flowline by collection tank；Sludge is periodically discharged into station through discharge pipeline and reclaims pond.

Embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings：

The pot type oil-polluted water biochemical treatment apparatus.What it was realized in：Water enters middle and upper part cloth by water inlet pipe Water pipe 2 starts water distribution.It is dissolved air release 3 below water-locator, the water outlet of release 3 is to pass through reflux pump water inlet pipe 13 by reflux pump Draw the water handled in tank and enter air-dissolving apparatus, the dissolved air water of generation discharges the dissolved air water of micro-bubble by release 3, Oil slick and particulate contamination during band is leaked water during bubble in dissolved air water is floated up enter collection tank 4, pass through collection tank 4 Outside the delivery pipeline drain tank of connection.Water inlet distributor 2 and release 3 are placed in the central tube at Guan Nei centers, constitute gas Floating region 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, stand Body elasticity filler, soft or semi soft packing.Gas from roots blower is sent to below filler region by air line Aeration coil pipe on, be discharged into by gas release device 6 in water body, life provided for the microorganism that is attached in tank body on filler region Long required dissolved oxygen.Water down moves across the microbial reaction being attached in filler body and removes oil emulsion and dissolved oil；Place The tilting box 7 that water after reason enters below aeration coil pipe, the inside of tilting box 7 has inclined plate packing to play the work that oil removal is removed in sedimentation With.Water after the connection processing of collector pipe 8 above the inclined plate packing of tilting box 7 enters collector pipe 8 by tilting box 7.And by center Water is delivered to water outlet Adjustable water tank 5 and discharged by post.Newel has exhaust outlet 15 in upper end, plays regulation newel current pressure Power and outer air pressure balance.
