Abstract

The utility model relates to an efficient inclined plate sedimentation tank which comprises inclined plate fillers (1) and a tank body (4) which is provided with a wastewater inlet (2) and a clean water outlet (3); wherein, the tank body is separated into an upper layer and a lower layer which are a drainage area (5) and a sedimentation area (6), and the bottom of the sedimentation area is a sludge concentration area (7); a water distribution area (8) is separated from a partition sheet (13) which is higher than the inclined plate fillers in the inclined plate fillers; the wastewater inlet is higher than the inclined plate fillers and is corresponding with the upper part of the water distribution area; a plurality of flumes (9) are positioned on the top parts of the inclined plate fillers and each flume end is connected with the clean water outlet; a mechanical sludge withdrawal device (10) is arranged at the sludge concentration area; the tank body is additionally provided with a sludge withdrawal well (11) and the sludge is transported into the sludge withdrawal well through the static pressure of the pipelines after being collected and concentrated by the mechanical sludge withdrawal device. The inclined plate sedimentation tank has the sedimentation efficiency twice or 4 times higher than the sedimentation efficiency of the conventional sedimentation tanks on per unit area and can greatly save the occupied area as well as saving the one-time investment cost; the mode of the water distribution can be improved and the sludge withdrawal effect can be strengthened, which effectively solves the phenomena of the short-lived flow and the dead angles of a plurality of present sedimentation tanks and at the same time solves the problem of the suspended substances being carried by the effluent.

Description

A kind of efficient inclined-plate clarifying basin

Technical field

The utility model relates to the sedimentation basin in the water treatment, especially relates to a kind of inclined-plate clarifying basin.

Background technology

Existing sedimentation pond for water treatment mainly is divided into rectangular sedimentation tank, vertical sedimentation basin, radical sedimentation basin and ramp type sedimentation basin, and more or less all there are the following problems for these sedimentation basins:

1, local water distribution is inhomogeneous, causes sedimentation basin short flow phenomenon and dead angle phenomenon to occur, influences sedimentation basin mud-water separation effect.

2, water distributing area and settling zone sludge stream clash, and cause current to carry a large amount of precipitating sludges, influence the precipitation process effect.

3, surface loading is little, and floor space is big, and investment is high.

The utility model content

The purpose of this utility model, just provide a kind ofly have that surface loading is big, even water distribution and the little efficient inclined-plate clarifying basin of floor space.

For achieving the above object, efficient inclined-plate clarifying basin of the present utility model, comprise swash plate filler and the pond body that has sewage import and pure water inlet, it is characterized in that: described pond body is divided into the two-layer up and down of catchment and settling zone with the swash plate filler, the bottom of settling zone is the mud enrichment region, is separated out a water distributing area between the centre of swash plate filler is with the dividing plate that is higher than the swash plate filler, and the sewage import is provided with water distributing area, many tanks are arranged on the top of swash plate filler, and each tank end is connected to pure water inlet.

Described swash plate length from more than or equal to 0.5m to being less than or equal to 2m, the angle of inclination of swash plate from more than or equal to 45 ° to being less than or equal to 75 °, the aperture of swash plate also from more than or equal to ￠ 40mm to being less than or equal to ￠ 100mm.

On the basis of the above, this novelly also can do further various improvement:

Described mud enrichment region is equipped with the mechanical dredge device, and it drives the cleaning shoe that is in the mud enrichment region by the motor that is installed in body top, pond by vertical power transmission shaft and constitutes.

Described pond body has been set up blowoff chamber, and mud is collected concentrated back through the mechanical dredge device and is delivered in the blowoff chamber by duct static pressure.

Beneficial effect: the sedimentation effect of efficient inclined-plate clarifying basin of the present utility model on unit are exceeds 2～4 times of conventional sedimentation basins, saves once capable input cost simultaneously so can save floor space to a great extent.Improve water distribution manner and strengthen sludge discharge effects, efficiently solve short flow phenomenon of existing a large amount of sedimentation basins and dead angle phenomenon, efficiently solve water outlet simultaneously and carry the suspension problem.

The specific embodiment

As shown in Figure 1 to Figure 3, efficient inclined-plate clarifying basin of the present utility model, comprise swash plate filler 1 and the pond body 4 that has sewage import 2 and pure water inlet 3, pond body 4 is divided into the two-layer up and down of catchment 5 and settling zone 6 with swash plate filler 1, the bottom of settling zone is a mud enrichment region 7, swash plate length from more than or equal to 0.5m to being less than or equal to 2m, the angle of inclination of swash plate from more than or equal to 45 ° to being less than or equal to 75 °, the aperture of swash plate also from more than or equal to ￠ 40mm to being less than or equal to ￠ 100mm.Centre at the swash plate filler is separated out a water distributing area 8 with 13 on the dividing plate that is higher than the swash plate filler, and the sewage import is higher than the swash plate filler corresponding to water distributing area top, and many tanks 9 are arranged on the top of swash plate filler, and each tank end is connected to pure water inlet; At the mud enrichment region mechanical dredge device 10 is housed, it drives the cleaning shoe 16 that is in the mud enrichment region by the motor 14 that is installed in body top, pond by vertical power transmission shaft 15 and constitutes; The pond body has been set up blowoff chamber 11, and mud 12 is collected concentrated back through the mechanical dredge device and is delivered in the sewer catch basin by duct static pressure.

So when sewage enters into water distributing area, can obtain uniform flow shape, pass from the below of swash plate filler on the filler to the catchment, casual at last intake chamber is discharged from pure water inlet.

In sedimentation basin, increase the mechanical dredge device, but the collection of reinforcement sludge and concentrated, and be provided with special blowoff chamber, mud concentrates the back through mechanical collection and is delivered in the sewer catch basin by duct static pressure.
