Abstract
The utility model relates to an inclined tube sedimentation pool for sewage treatment. A water inlet and a water outlet are respectively arranged on the upper parts of the two opposite pool walls of a pool body, the bottom of the pool wall at the same side with the water outlet is provided with a sludge outlet, and the pool bottom gradually inclines from one side of the water inlet to one side of the sludge outlet downwards. The pool body is divided into an upper layer and a lower layer by a group of inclined tubes in the pool, the upper layer is a clear water zone, and the lower layer is a water distributing zone and a sedimentation zone. The water inlet is communicated with the sedimentation zone by a vertical water inlet channel, an inlet at the lower end of each inclined tube is communicated with the water distributing zone and the sedimentation zone and is close to one side of the sludge outlet, and an outlet at the upper end of each inclined tube is close to one side of the water inlet. The inclined tube and the pool wall of the water inlet channel form a triangle dead angle zone, and a damping board is arranged at the bottom edge of the triangle dead angle zone, namely one side close to the water distributing zone. A damping reinforcement board is additionally arranged at one end of the damping board close to the inclined tube. Because the structure of the pool body is improved, the damping board is tightly matched with the inclined tube, the floccule flowing into the clear water zone is obviously reduced, and thereby, the water outflow quality is effectively improved.
Description
Technical field
The utility model belongs to a kind of tube settler that coagulant sedimentation is disposed of sewage that is used for.
Background technology
Industrial, adopt coagulant sedimentation to handle usually for the sewage that contains suspended solid or colloid pollution thing.Its processing procedure mainly comprises: sewage enters and fully mixes after mixing pit adds coagulant and flocculation aid, sewage enters coagulation reaction tank and reacts then, suspension or colloid pollution thing are condensed into bigger floccule, and last sewage enters sedimentation basin sedimentation floccule, remove mud and clear water side by side.Sedimentation basin is very important equipment in whole process, and its structure is also comparatively complicated.Industrial, tube settler is used morely.The structure of general tube settler is: body two relative pool wall tops in pond have water inlet and delivery port, have sludge outlet with the pool wall bottom of delivery port homonymy, progressively tilt from high to low from water inlet one side to sludge outlet one side at the bottom of the pond, the pond body is separated into two-layer up and down by one group of inclined tube in the pond, the upper strata is a clear water zone, lower floor is cloth pool and settling zone, water inlet communicates with the settling zone by a vertical intake tunnel, inclined tube is placed on the shelf, the lower end import of inclined tube is with the cloth pool and the settling zone communicates and nearly sludge outlet one side, and the upper end outlet is near a side of water inlet.Inclined tube and intake tunnel pool wall form the dead angle area that the vertical section is a right angled triangle, promptly by a side in cloth pool one damping sheet are arranged on the base of this right angled triangle, and this damping sheet flushes with the shelf of placing inclined tube.Sewage enters cloth pool and settling zone from water inlet by vertical passage, enters clear water zone by inclined tube then.Owing to the damping action that stops of inclined tube, cloth pool and settling zone are returned in the floccule sedimentation, and clear water is discharged by delivery port, and sludge outlet generally is equipped with valve, intermittent discharge mud.But, there is following defective in this tube settler, because damping sheet is different with material, the shape of inclined tube, making between damping sheet edge and the inclined tube can not tight connecting, cause the short circuit of part current, make floccule enter dead angle area from this slit, flow into clear water zone by slit between inclined tube outlet and the sedimentation basin edge then with current, cause the general mud of water outlet, thereby influenced effluent characteristics.
Summary of the invention
Technical problem to be solved in the utility model is by the tube settler parts being improved, improving the effluent characteristics of tube settler.
It below is the technical scheme that the utility model solves the problems of the technologies described above.
A kind of tube settler that adopts coagulant sedimentation, body two relative pool wall tops in pond have water inlet and delivery port, have sludge outlet with the pool wall bottom of delivery port homonymy, progressively tilt from high to low from water inlet one side to sludge outlet one side at the bottom of the pond, the pond body is separated into two-layer up and down by one group of inclined tube in the pond, the upper strata is a clear water zone, lower floor is cloth pool and settling zone, water inlet is identical with the settling zone by a vertical intake tunnel, inclined tube is placed on the shelf, the lower end import of inclined tube is with the cloth pool and the settling zone communicates and nearly sludge outlet one side, and the upper end outlet is near a side of water inlet.Inclined tube and intake tunnel pool wall form the dead angle area that the vertical section is a right angled triangle, promptly there is a damping sheet on base at this right angled triangle by a side in cloth pool, this damping sheet flushes with the shelf of placing inclined tube, it is characterized in that a end at the nearly inclined tube of described damping sheet, increase by a damping reinforcement plate, compound one deck elastic damping material on described damping reinforcement plate.
Above-mentioned elastic damping material can adopt rubber or plastics.
Compared with prior art, the utility model makes tight connecting between damping sheet and the inclined tube because the structure of pond body is improved, and flows into the clear water zone floccule and obviously reduces, thereby improved effluent characteristics effectively.

The specific embodiment
In Fig. 1 and Fig. 2, the pond body two relative pool wall tops of tube settler have water inlet 1 and delivery port 2, have sludge outlet 3 with the pool wall bottom of delivery port homonymy, sludge outlet generally is equipped with valve, intermittent discharge mud, progressively tilt from high to low from water inlet one side to sludge outlet one side at the bottom of the pond, the pond body is separated into two-layer up and down by one group of inclined tube 8 in the pond, the upper strata is a clear water zone 5, lower floor is cloth pool and settling zone 6, and water inlet is identical with the settling zone by a vertical intake tunnel 7, and inclined tube is placed on the shelf, the lower end import of inclined tube is with the cloth pool and the settling zone communicates and nearly sludge outlet one side, and the upper end outlet is near a side of water inlet.It is the triangle dead angle area that inclined tube and intake tunnel pool wall form a vertical section, promptly the side by the cloth pool has a damping sheet 4 on this leg-of-mutton base, this damping sheet flushes with the shelf of placing inclined tube, end at damping sheet 4 nearly inclined tubes, increase by a damping reinforcement plate 9, damping reinforcement plate 9 width are between 20～200mm.In order to increase the damping action of resistance to water-flow and current laminar flow internal layer, carrying out plucking on this damping reinforcement plate handles, and then compound one deck elastic damping material 10, this elastic damping material can adopt the rubber of waterproof or plastics etc., adopts corrosion-resistant, elastomeric waterproof ethylene propylene diene rubber of low-density or polyurethane plastics in the utility model.In order to strengthen the effect of forward resistance to water-flow and minimizing reverse flow, further stop floccule to enter dead angle area, when spoil disposal, make simultaneously dead angle area mud and the more smooth mud accumulation area that enters of floccule, also can have an anisotropic damping ripple of current what the elastic damping layer upper surface of damping reinforcement plate 9 made that many groups protrude, the damping ripple can be made streamlined or arrowhead form etc., as Fig. 3, shown in Figure 4, in the utility model, adopt the arrowhead form ripple, the direction of arrow is identical with the current inflow direction, can make the waste water of the band floccule in cloth pool be difficult for entering dead angle area like this.
