Abstract
The utility model discloses an overflow type sedimentation tank, relate to a water treatment facility, and in particular to a structure of a sedimentation tank. The overflow type sedimentation tank comprises a sedimentation tank body (2) with a rectangular structure, wherein an inflow port (1) is formed on a wide side of the sedimentation tank body; a clean water reservoir (5) is arranged on the other side of the sedimentation tank body, which is opposite to the inflow port,, and is same as the sedimentation tank body in width; a water discharge outlet (6) is formed at the lower part of the clean water reservoir; a fresh water outlet (4) is formed on the upper edge of the junction of the sedimentation tank body and the clean water reservoir and is same as the inner side of the sedimentation tank body in width; and a horizontally-arranged overflow dam (3) is arranged on the edge of the lower side of the fresh water outlet, adopts a structure in the shape of a strip-shaped plate, and is same as the fresh water outlet in width. The utility model solves the problems of a conventional sedimentation tank that when fresh water flows out, water is not distributed uniformly, and the mud below the sedimentation tank is raised, resulting in a poor water treatment effect.
Description
Technical field
The utility model relates to water processing establishment, is specifically related to a kind of sedimentation basin structure.
Background technology
Sedimentation basin is to use a kind of structures that precipitation is removed suspension in the water.Sedimentation basin widely uses in wastewater treatment.Its pattern is a lot, can be divided into three kinds of flat flow, vertical-flow and radial-flows by the pool inner water flow path direction.
The effect of sedimentation basin: generally be before biochemical or the structures of biochemical back mud-water separation, be mostly the mud that separating particles is thinner.Be called preliminary sedimentation tank before the biochemistry, the mud inorganic constituents of deposition is more, and moisture percentage in sewage sludge is low with respect to second pond mud.Be positioned at biochemical sedimentation basin afterwards and be commonly referred to as second pond, be mostly organic sludge, moisture percentage in sewage sludge is higher.
At present, water treatment commonly used is a rectangular sedimentation tank with sedimentation basin, and it is made up of entery and delivery port, current part and three parts of sludge bucket.Rectangular sedimentation tank is many to be built with concrete, or with the Tu Chi of masonry lining.The rectangular sedimentation tank simple structure, sedimentation effect is good, and stable work in work use extensively, but floor space is bigger.If add mud scraper or adopt machinery to get rid of, can improve the sedimentation basin operating efficiency to the big sediment of proportion.
The shortcoming that existing sedimentation basin exists is: water distribution was inhomogeneous when clear water flowed out, and can the mud of sedimentation basin below be started when clear water flows out, and caused the water treatment weak effect.
The utility model content
The utility model provides a kind of overflow-type sedimentation basin, and water distribution was inhomogeneous when the utility model had solved existing sedimentation basin and exists clear water to flow out, and can the mud of sedimentation basin below be started when clear water flows out, and caused the problem of water treatment weak effect.
For addressing the above problem, the utility model adopts following technical scheme: the overflow-type sedimentation basin, comprise sedimentation basin 2, and sedimentation basin 2 is rectangle structures, on a broadside of sedimentation basin 2, inflow port 1 is arranged; Other side at the sedimentation basin 2 relative with inflow port 1 is provided with clear water reserviors 5, and sedimentation basin 2 is identical with clear water reserviors 5 width, in the bottom of clear water reserviors 5 discharge outlet 6 is arranged; There is a clear water flow export 4 upper edge at sedimentation basin 2 and clear water reserviors 5 connecting portions, and clear water flow export 4 is identical with sedimentation basin 2 inboard width; At clear water flow export 4 lower sides a horizontally disposed downflow weir 3 is arranged along the position; Said downflow weir 3 is rectangular slab structures, and the length of downflow weir 3 is identical with the width of clear water flow export 4.
Further, the overflow-type sedimentation basin of the utility model also has following characteristics: the width L of said downflow weir 3 is the 100-1000 millimeter.Preferably: the width L of said downflow weir 3 is the 400-600 millimeter.
The utility model adopts the downflow weir structure, it can guarantee the primary water of post precipitation can be along the pond the wide clear water reserviors that flow into equably.Water distribution was even when the utility model can guarantee the clear water outflow, can the mud of sedimentation basin below not started when clear water flows out, and had improved the water treatment effect.
Description of drawings
Fig. 1 is the utility model side sectional view;
Fig. 2 is the vertical view of Fig. 1.
Symbol description among the figure: inflow port 1, sedimentation basin 2, downflow weir 3, clear water flow export 4, clear water reserviors 5, discharge outlet 6, slag-drip opening 7.
The specific embodiment
Shown in Fig. 1-2, the overflow-type sedimentation basin comprises sedimentation basin 2, and sedimentation basin 2 is rectangle structures, on a broadside of sedimentation basin 2, inflow port 1 is arranged; Other side at the sedimentation basin 2 relative with inflow port 1 is provided with clear water reserviors 5, and sedimentation basin 2 is identical with clear water reserviors 5 width, in the bottom of clear water reserviors 5 discharge outlet 6 is arranged; There is a clear water flow export 4 upper edge at sedimentation basin 2 and clear water reserviors 5 connecting portions, and clear water flow export 4 is identical with sedimentation basin 2 inboard width; At clear water flow export 4 lower sides a horizontally disposed downflow weir 3 is arranged along the position; Said downflow weir 3 is rectangular slab structures, and the length of downflow weir 3 is identical with the width of clear water flow export 4.
The width L of said downflow weir 3 is 500 millimeters.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
Claims (3)
1. the overflow-type sedimentation basin comprises sedimentation basin (2), and sedimentation basin (2) is a rectangle structure, on a broadside of sedimentation basin (2), inflow port (1) is arranged; It is characterized in that be provided with clear water reserviors (5) in the other side of the sedimentation basin (2) relative with inflow port (1), sedimentation basin (2) is identical with clear water reserviors (5) width, in the bottom of clear water reserviors (5) discharge outlet (6) is arranged; There is a clear water flow export (4) upper edge at sedimentation basin (2) and clear water reserviors (5) connecting portion, and clear water flow export (4) is identical with the inboard width of sedimentation basin (2); At clear water flow export (4) lower side a horizontally disposed downflow weir (3) is arranged along the position; Said downflow weir (3) is rectangular slab structure, and the length of downflow weir (3) is identical with the width of clear water flow export (4).
