Description
Technical field
The present invention relates to field of environment pollution control more particularly to it is a kind of suitable for rural area rainwash suspended matter removing
Double helix sedimentation basin.
Background technique
China increasingly payes attention to environmental protection in recent years, persistently has an effect in fwaater resources protection, and industrial wastewater and city are raw
The point-source pollutions such as sewage living obtain a degree of solution.However it is weak due to the extensive life style in rural area and with water knowledge,
Water environment load increasingly aggravates, and corresponding environmental facility construction lag, to cause the sharply deterioration of Rural Water Environment, to have
Samll cities and towns' water environment eutrophication that machine object, nitrogen and phosphorus richness product are characterized is in spreading trend.Runoff pollution is that rural area non-point source is dirty
One big factor of dye, the main source of runoff pollution is domestic sewage of villages and small towns, rural area solid waste, farmland agriculture chemical, water
Soil flow mistake etc..Current research is concentrated mainly on Runoff and the research of rural area agricultural surface runoff in city, and for allusion quotation
The research of type village residential block runoff pollution treatment is less.Major part rural area runoff treatment compares shortage at present, existing
Some methods mainly handle rural area rainwash waste water by building small-scale waste water treating stations.Most of small-scale waste water processing
The process flow stood mainly passes through construction pipeline or irrigation canals and ditches collect rainwash, then passes through certain technique such as sedimentation basin, people
Work wetland, oxidation pond etc. handle waste water, finally will treated discharge of wastewater, to reduce pollutant in rainwash
Pollution to environment.Wherein sedimentation basin is widely applied in the rainwash waste water treatment process of rural area, however current sedimentation basin
Big multiprocessing waste water is inefficient.
A kind of high-efficient vertical flow inclined-plate clarifying basin is disclosed in Chinese patent CN201320005376.2, is set in the middle part of pond body
Central tube, reaction zone and inclined plate packing are set, raw water to be processed passes through after adding flocculation medicament by central tube, reaction zone, inclined plate packing
After be discharged.The flocculation ability of suspended matter in raw water can be enhanced in the invention, promotes the flocculation sedimentation of suspended matter.But because of its main benefit
Suspended matter in water is intercepted and precipitated with the effect of inclined plate, and the flow velocity of water cannot be too big, therefore handles the efficiency of raw water relatively
It is low.
A kind of vertical-flow inclined-tube sedimentation tank is disclosed in Chinese patent CN201420526214.8, inner barrel is mainly wrapped
Containing central draft tube, taper reflecting plate, inclined tube condiment, overflow weir etc., a wadding is formed between taper reflecting plate and inclined tube filler
Solidifying settled layer, intercepts the lightweight suspension object in water, and bulky grain suspended matter is intercepted by inclined tube filler.It can effectively remove raw water
In suspended matter, to reach purpose of purifying the water quality.But since it mainly utilizes gravity and inclined plate packing to remove in raw water
Suspended matter, so the flow that raw water is passed through cannot be too big, the efficiency for handling raw water is lower.
A kind of hydrocyclone is disclosed in Chinese patent CN201520801997.0, mainly include cylindrical body, cone,
Tangent feed inlet, the overflow port being located at the top of cylindrical body etc. with cylindrical body top.Hydrocyclone mainly utilizes cyclone
Structure rotates raw water to be processed in cyclone, so that suspended matter be made to be acted on by centrifugal force and be concentrated in cyclone inner wall
On face, slide under the effect of gravity from bottom desilting mouth be discharged, containing the less clear water of suspended matter from be inserted in cyclone center overflow
Head piece discharge.But because it mainly utilizes the suspended matter in centrifugal force separate waste water to be processed, separation and water density phase
The little particulate matter effect of difference is poor.
Summary of the invention
The purpose of the present invention is overcome equipment removing of the prior art for suspended matter separation in the rainwash of rural area to suspend
The lower defect of object efficiency provides a kind of equipment for separating rural area rainwash suspended matter.
In order to achieve the above object, the invention adopts the following technical scheme:

The process of processing sewage is as follows when double helix sedimentation basin of the present invention works:
Sewage enters this sedimentation basin from water inlet pipe 1, enters Swirl device 8 along cyclone water inlet pipe 7.Because sewage is therefrom
The tangential direction of 8 wall surface of heart cyclone enters Swirl device 8, so sewage can rotate inside Swirl device 8.It generates
Centrifugal force makes the de- steady, separation of the suspended matter in sewage.The biggish suspended matter of density can be because centrifugal force be gathered in Swirl device 8
Dope is formed in interior sidewall surface, is flowed downward along side wall.The lesser suspended matter of density will form clear liquid and pass through cyclone overflow pipe 5
It flows upwards out.The clear liquid that cyclone overflow pipe 5 flows out enters central draft tube 9, flows out from 9 bottom of central draft tube downwards, then
It flows up.Flow rate of water flow in central draft tube 9 is slower, and the suspended matter in clear liquid can be deposited in 10 outside wall surface of waterpower restraining plate
On, it is slid after accumulation into 15 base sludge enrichment region of sedimentation basin pond body, is discharged by sludge pipe 12.Contain density in Swirl device 8
Dope is formed after biggish suspended matter concentration and flows into impeller guide device 13 along the sliding of 8 inner wall of Swirl device, from water conservancy diversion
17 outflow of slot outlet, diversion trench, which exports 17 directions and 13 wall surface tangential direction of impeller guide device, certain angle, therefore dope stream
It can be rotated after to waterpower restraining plate 10, be gathered in suspended matter on 10 inner wall of waterpower restraining plate, and slide, pass through spoil disposal
Pipe discharge.The supernatant of sludge condensation area converges with the water outlet of central draft tube 9 water flow slowly to be flowed up along pond body, into inclined plate
Settling zone.By the effect of inclined plate, more tiny suspended matter is blocked to settle and be discharged into 15 bottom of sedimentation basin pond body, water
Stream continues upward through swallow-tail form overflow weir 2 and flows into overflow launder 3, and is discharged by the water outlet 16 of 3 bottom of overflow launder.It leads at center
9 top open-ended of flow cartridge, can observe water quality situation, and into water, delivering medicament promotes suspended matter precipitating according to actual needs.
From the process of above-mentioned sewage treatment as it can be seen that removing of this sedimentation basin especially suitable for rural area rainwash particulate matter,
But it is equally applicable to the removing of particulate matter in the waste water such as mining wastewater, waste water of paper mill, can efficiently be removed therein outstanding
Floating object, particulate matter.
Finally, it should be noted that embodiment of above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
Invention is explained in detail referring to aforementioned embodiments for pipe, those skilled in the art should understand that: its according to
It can so modify to technical solution documented by aforementioned embodiments, or part of technical characteristic is equally replaced
It changes；And these are modified or replaceed, each embodiment technical solution of the present invention that it does not separate the essence of the corresponding technical solution
Spirit and scope.
