Description
Technical field
The utility model belongs to technical field of sewage treatment equipment, is related to sedimentation basin, and in particular to one kind is suitable for thin
The high efficiency vertical sedimentation tank of grain sludge.
Background technique
With the development of society, water pollution is increasingly severe, but requirement of the people's lives quality to water quality is increasingly
It is high.The precipitation method can remove the sand grains in water removal, chemical precipitates, the wadding body of coagulation formation and the sludge after biological treatment.Precipitating
Process is simple and easy, good separation, is the significant process of water process, is widely used, almost can not in water treatment procedure
What is lacked has a unit.Precipitation has a natural sedimentation and two kinds of flocculation sedimentation, existing sedimentation basin be broadly divided into horizontal sedimentation tank,
Vertical sedimentation tank and three kinds of radial-flow sedimentation tank.
Vertical sedimentation tank refers to that sewage vertically flows in pond, and water enters pond by the water inlet pipe for being located at pond center from top to bottom
It is interior, slowly rise after umbellate form baffle is set in pipe being uniformly distributed waste water in pond along the entire cross-section of river, suspended matter is due to weight
Power enters in bottom of pond taper sludge bucket, and from pond surrounding, peripherally overflow weir flows out primary water.Before weir baffled or scum trough with
Dross is retained, guarantees effluent quality.Pond sets sludge pipe by pool wall on one side mud is periodically discharged by hydrostatic pressure.Vertical-flow precipitating
The advantages of pond is that occupied area is small, is usually used in handling water less than 20000m3The sewage treatment plant of/d.The pond body of vertical sedimentation tank
It is generally pylindrical or square.
Although it is small, easy to operate that vertical sedimentation tank has the characteristics that occupied area, but still has the following problems: due to heavy
Shallow lake pond pond body ratio of height to diameter is bigger, and the fine granule sludge to settle down is easy the side that dispersion is deposited in taper sludge bucket,
The settled layer that surrounding is high, centre is low is formed, excess sludge is difficult to be discharged from bottom mud discharging mouth in time, be easy in sludge bucket side heap
Product forms dead zone.And there may be local water distribution is uneven, it is easy that sedimentation basin is extremely caused short stream even dead angle phenomenon occur,
Influence sedimentation basin fine granule suspended impurity removal effect；Coagulation process usually requires stirring action, needs to consume a large amount of electricity
Can, it is easy to stir in sludge, influences top clear water；Fine granule is easy to flow out with water, and sedimentation effect is undesirable.
Summary of the invention
For the deficiencies in the prior art, the purpose of the utility model is to provide one kind to be suitable for fine grained dirt
The high efficiency vertical sedimentation tank of mud, to solve the high-efficient vertical flow sedimentation basin in the prior art lacked suitable for fine granule,
Existing vertical sedimentation tank dead zone easy to form, fine granule removal efficiency is lower caused by fine granule is flowed out with water
Problem.
In order to solve the above-mentioned technical problem, the application, which adopts the following technical scheme that, is achieved:
A kind of high efficiency vertical sedimentation tank suitable for fine granule, including pond body further include that be mounted on pond intracorporal
Central tube, reflecting plate, strainer and lead mud mud guard；

Occupied area and save the cost are lacked；
(II) the high efficiency vertical sedimentation tank suitable for fine granule of the utility model is provided with spoiler, if water
For stream by baffle reflection rising directly after central tube, it is excessive to will lead to flow velocity, is unfavorable for precipitation and separation, therefore in central tube
Staggeredly rectangle spoiler is conducive to plus flow path, increase flow-disturbing alleviate the impact of water flow for setting, slows down flow velocity, while advantageous
In the further flocculating setting of particle；
(III) the high efficiency vertical sedimentation tank suitable for fine granule of the utility model is also arranged by multiple groups fan-shaped
Mud mud guard is led, leading mud mud guard is the annular plate being spliced by petal-like bulk, can be shunk with hydraulic drive, is adjusted
The whole tilt angle for leading mud mud guard.It leads mud mud guard to be located above sludge bucket, the suspended matter under precipitating can be oriented to sludge
Bucket middle part can faster, more stably assemble in the middle part of sludge bucket, alleviate due to pond body ratio of height to diameter is big and sludge is in sludge bucket side
The phenomenon that face is assembled, sludge is avoided to accumulate to form dead zone in sludge bucket side.Simultaneously because the tilt angle for leading mud mud guard can
To adjust, therefore sludge is difficult to deposit on leading mud mud guard.And it can stop due to the impurities in water that is stirred when spoil disposal again
Secondary floating.And guiding process is toppled over similar to flexibility, can be promoted effect of settling, further be promoted water quality.
(IV) the high efficiency vertical sedimentation tank suitable for fine granule of the utility model is also arranged by multiple groups in pond
Internal wall is provided with the strainer for separating gathering ground and cement Disengagement zone, and for annular shape, all water outlets can all pass through strainer filtering.Filter
Net can stop the flocculated suspension object driven by water flow, prevent fine suspension from flowing into water outlet, influence effluent quality, can be into one
Step reduces delivery turbidity.
