Description

Variable cross-section horizontal sedimentation tank
Technical field
The utility model relates to field of Environment Protection, particularly a kind of variable cross-section horizontal sedimentation tank being applicable to sandstone processing flushing waste water pretreatment stage.
Background technology
Horizontal sedimentation tank pond body plane is rectangle both at home and abroad at present, general and flocculation basin is built jointly, former water is through adding coagulant after hybrid reaction abundant in flocculation basin, and the water distribution of perforated wall precipitates, and spoil disposal then adopts the modes such as sludge hopper gravity spoil disposal, perforated pipe spoil disposal and mechanical dredge.Horizontal sedimentation tank is a kind of tradition precipitation structures, is widely used in the depositing technology of cities and towns water treatment plant, sewage treatment plant.
Sandstone processing flushing waste water silt content is large, gravel size is widely distributed, horizontal sedimentation tank is referred in the sand setting technique of sandstone processing flushing waste water pretreatment stage, although sedimentation effect is better, but flocculation postprecipitation is deposited on together, water permeability is poor, follow-up silt particle is separated, drying and other treatment workload is too large, and treatment effect is undesirable.
Tradition horizontal sedimentation tank body refuse utilization rate is low, does not even utilize, causes significant wastage.
Sandstone processes the development of pretreating process through decades of flushing waste water, although achieve certain achievement, the subsequent treatment problems such as effect is all undesirable, a large amount of silt particle separation still need further improvement.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of variable cross-section horizontal sedimentation tank, can realize fractional precipitation.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of variable cross-section horizontal sedimentation tank, comprises sedimentation tank body, and one end that sedimentation tank body is connected with inlet channel is narrower, and the one end be connected with effluent trough is wider;
Be provided with multiple sludge hopper in the bottom of sedimentation tank body, each sludge hopper is along the order arrangement from inlet channel to effluent trough.
Grid and water distribution wall is also provided with between inlet channel and sedimentation tank body.
Effluent trough front end is provided with overflow plate.
The bottom of sedimentation tank body along the order from inlet channel to effluent trough, is separated into coarse sand settling zone, medium sand settling zone, fine deposition district and mud sediment district by described sludge hopper successively.
Each settling zone is made up of multiple sludge hopper arranged side by side.
Along the order from inlet channel to effluent trough, the length of each sludge hopper is narrower more rearward.
The rear and front end of sedimentation tank body is provided with sedimentation basin pillar.
Described sedimentation tank body flat shape is trapezoidal.
Traditional horizontal sedimentation tank type of precipitation only has flocculation sediment, does not consider crowded precipitation and compression precipitating.The utility model then make use of the principle of crowded precipitation and compression precipitating, and in infall process, sand mud interferes with each other, and produces crowded precipitation, and under gravity, compression lower sediment, produces compression precipitating to silt particle.In precipitation process, cohesion or flocculation occur, suspended particulate is collided with each other condensation, and granular mass increases gradually, and sinking speed is accelerated gradually.
A kind of variable cross-section horizontal sedimentation tank that the utility model provides, by adopting the structure of variable cross-section, make sandstone process flushing waste water and produce different flow velocitys at different cross section place, thus make the sludge hopper of bottom collect coarse granule, middle particle, fine grained and special fine grained respectively by sedimentation probability.Make use of the feature that sandstone processing flushing waste water silt content is high, gravel size is widely distributed, realize the process of silt particle fractional precipitation, thus improve the water penetration of silt particle, be convenient to mummification.

Detailed description of the invention
As in Fig. 1 ~ 2, a kind of variable cross-section horizontal sedimentation tank, comprises sedimentation tank body 11, and one end that sedimentation tank body 11 is connected with inlet channel 1 is narrower, and the one end be connected with effluent trough 5 is wider; Preferred as in Fig. 1, described sedimentation tank body 11 flat shape is trapezoidal.
Be provided with multiple sludge hopper 4 in the bottom of sedimentation tank body 11, each sludge hopper 4 arranges along from inlet channel 1 to the order of effluent trough 5.
Sandstone flushing waste water flows to sedimentation tank body 11, in waste water, different-grain diameter silt particle etc. sink under gravity, horizontal direction speed reduces because current increase through area of section, silt particle particle diameter is larger, sinking speed is faster, and particle diameter is less, and sinking speed is slower, thus achieve the hydraulic classiciation of silt particle particle, as shown in Figure 3.
After silt particle classification preliminary sedimentation, the sand setting grain diameter in sedimentation tank body 11 front end sludge hopper 4 comparatively evenly, concentrate, water penetration better, be convenient to mummification.Meanwhile, the sand material after mummification can need directly to recycle to sand particles particle diameter according in engineering, and in back segment sludge hopper 4, main sediments is mud, and natural-dehydration condition is poor, because its amount is less, can adopt centrifuge or filter press dehydration post processing.
Be separated the former water after sandstone and add flocculant after preliminary sedimentation tank effluent trough 5 is discharged, in sedimentation basin, complete further flocculation sediment.
The utility model realizes silt particle classification process (sedimentation), decreases a large amount of follow-up work and relevant device scale, for follow-up silt particle mummification is layed foundation.
In preferred scheme, between inlet channel 1 and sedimentation tank body 11, be also provided with grid 2 and water distribution wall 3.The grid 2 arranged is for removing in waste water the foreign material such as leaf.The water distribution wall 3 arranged is provided with multiple uniform hole, for making current uniform distribution in the plane.
Preferred scheme is as in Fig. 2, and effluent trough 5 front end is provided with overflow plate.The overflow plate arranged makes draining not affect sedimentation.
Preferred scheme is as in Fig. 1 ~ 2, and the bottom of sedimentation tank body 11 along from inlet channel 1 to the order of effluent trough 5, is separated into coarse sand settling zone 7, medium sand settling zone 8, fine deposition district 9 and mud sediment district 10 by described sludge hopper 4 successively.Structure thus, realizes the classification one_to_one corresponding according to sand material, in coarse sand settling zone 7, the sand material in medium sand settling zone 8 and fine deposition district 9 after mummification, can directly recycling.Thus reduction cost of material.
Preferred scheme is as in Fig. 1, and each settling zone is made up of multiple sludge hopper 4 arranged side by side.Structure thus, realizes the effect of better Compression Settlement, is convenient to collection and the discharge (can adopt but be not limited to the various sediment outflow modes such as machinery, waterpower, gas lift) of silt particle simultaneously.
Preferred scheme is as in Fig. 1 ~ 2, and along from inlet channel 1 to the order of effluent trough 5, the length of each sludge hopper 4 is narrower more rearward.As in Fig. 2, coarse sand settling zone 7 length is from left to right the longest, and mud sediment district 10 is then the shortest, thus structure, can utilize the callable raw materials such as preceding coarse sand settling zone 7 as far as possible.
The rear and front end of sedimentation tank body 11 is provided with sedimentation basin pillar 6.Structure thus, realizes the secure support to sedimentation tank body 11.Sedimentation tank body 11 is pool wall concrete wall when concrete pool structure, is basis, post, beam assembly when steel construction.
