Abstract
The utility model discloses a high-speed coagulative precipitation tank which comprises a tank body with a circular plane figure, wherein a tapered silting bucket is arranged at the bottom of the tank body; a precipitation area is arranged at the upper part of the tank body; a sludge area is arranged at the lower part of the tank body; a cushioning area is arranged between the precipitation area and the sludge area; inclined boards are arranged on the surrounding wall of the cushioning area at equal intervals; a water inlet pipe is arranged in the center of the tank body; a reflection baffle is arranged below the water inlet pipe; two overflow weirs are arranged at the upper part of the precipitation area along the periphery of the tank body and are connected with the water outlet pipe; and the tapered silting bucket is connected with a sludge discharge pipe. According to the utility model, as the inclined boards are arranged on the surrounding wall of the tank body at equal intervals, the precipitation efficiency can be greatly improved, the precipitation time is shortened, the hydraulic load is increased, and the volume of the precipitation tank is decreased. With the adoption of the two overflow weirs, the water passing speed is increased, and the efficiency is improved. In addition, the utility model has the advantages that the tank occupies small area and saves space.
Description
Technical field
The utility model belongs to water processing establishment, is specifically related to a kind of high speed coagulative precipitation tank.
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.Sedimentation basin generally is before biochemical or the structures of biochemical back mud-water separation, is mostly the mud that separating particles is thinner.Be called preliminary sedimentation tank before the biochemistry, the sedimentation basin that is positioned at after biochemical is commonly referred to as second pond.The mud inorganic constituents of preliminary sedimentation tank deposition is more, and moisture percentage in sewage sludge is low with respect to second pond mud.Mostly the mud of second pond deposition is organic sludge, and moisture percentage in sewage sludge is higher.Can reduce suspension content in the sewage as before the aeration tank, establishing primary sedimentation pond, alleviate the biological treatment load.Behind the aeration tank, establish the secondary sedimentation tank activated sludge that can dam.In addition, the chemical precipitation pond that after two stage treatment, is provided with in addition, i.e. dosing coagulant in sedimentation basin is difficult to biodegradable organic matter, material that can be oxidized and the removal efficient of producing color substance etc. in order to raising.
The pattern of sedimentation basin 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 rectangular sedimentation tank simple structure, sedimentation effect is good, and stable work in work use extensively, but floor space is bigger.This pond of vertical sedimentation basin floor space is little, but the degree of depth is big, is taper at the bottom of the pond, and construction is difficulty.The radial-flow type sedimentation tank depth is less but diameter is bigger.In recent years the novel swash plate or the tube settler that are designed to mainly add swash plate or inclined tube exactly in the pond, can improve deposition efficiency greatly, shorten the sedimentation time, reduce the sedimentation basin volume.Shortcomings such as but have swash plate, inclined tube to be prone to fouling, the growth film produces scum silica frost, and maintenance load is big, and tubing, sheet material life-span are low.
The utility model content
The purpose of the utility model is the defective that exists to prior art, provides a kind of sedimentation basin floor space little, is easy to construction, and deposition efficiency is high, high speed coagulative precipitation tank easy to maintenance.
Realize that the technical scheme that the utility model purpose adopts is: the high speed coagulative precipitation tank comprises that planar graph is circular pond body, and body bottom in pond is the heavy bucket of taper, and top is the settling zone; The bottom is the mud district, is buffering area between settling zone and the mud district, and the buffering area perisporium is equidistantly established hang plate; Pool center is provided with water inlet pipe, and reflecting curtain is established in the water inlet pipe below, and the body periphery is provided with the twice downflow weir to top, settling zone along the pond; Downflow weir is connected with outlet pipe, and the heavy bucket of taper is connected with discharge pipeline.
The angle of said hang plate and vertical line is 30o.
The utility model in the pond body perisporium equidistantly establish hang plate, can improve deposition efficiency greatly, shorten the sedimentation time, improve hydraulic load, reduce the sedimentation basin volume.Set twice downflow weir can improve water speed, raises the efficiency.Also to have floor space little for the utility model in addition, saves the advantage in space.
Below in conjunction with accompanying drawing the utility model is made and to be further specified.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
Shown in accompanying drawing, the high speed coagulative precipitation tank comprises that planar graph is circular pond body 8, and body 8 bottoms in pond are the heavy bucket 6 of taper; Top is the settling zone, and the bottom is the mud district, is buffering area between settling zone and the mud district; Buffering area along the pond body 8 perisporiums equidistantly establish hang plate 3, hang plate 3 is 30o with the angle theta of vertical line a, body 8 centers in pond are provided with water inlet pipe 9; Water inlet pipe 9 be connected from the water pipe outside the pond 1, reflecting curtain 4 is established in water inlet pipe 9 belows, the body periphery is provided with twice downflow weir 2 to top, settling zone along the pond; Downflow weir 2 is connected with outlet pipe 7, and the heavy bucket 6 of taper is connected with discharge pipeline 5.
Operation principle:
The water inlet pipe 9 that waste water is introduced pool center by water pipe 1 gets in the pond from top to bottom; The hang plate 3 and the whole cross-section of river along perisporium reflecting curtain 4 under the water inlet pipe 9 evenly distributes waste water in the pond after slowly rise; Suspended substance sedimentation gets in the heavy bucket 6 of pond base cone shape; The twice downflow weir 2 of primary water around from the pond flows into outlet pipes 7 and discharges, and the mud that is deposited at the bottom of the pond leans on hydrostatic pressing regularly to be discharged by discharge pipeline 5.
Claims (2)
1.
a kind of high speed coagulative precipitation tank comprises that planar graph is circular pond body, it is characterized in that body bottom, pond is the heavy bucket of taper; Top is the settling zone, and the bottom is the mud district, is buffering area between settling zone and the mud district; The buffering area perisporium is equidistantly established hang plate, and pool center is provided with water inlet pipe, and reflecting curtain is established in the water inlet pipe below; The body periphery is provided with the twice downflow weir to top, settling zone along the pond, and downflow weir is connected with outlet pipe, and the heavy bucket of taper is connected with discharge pipeline.
