Abstract

The utility model discloses a secondary inclined-tube sedimentation tank. The secondary inclined-tube sedimentation tank comprises a sedimentation tank main body and a sludge bucket; a sedimentation tank body comprises a primary sedimentation tank and a secondary sedimentation tank in adjacent arrangement; sewage in a water distribution groove is drained by a water distribution tube to the bottom of a tank body; the primary sedimentation tank and the secondary sedimentation tank are internally provided with inclined tubes; discharge water in the primary sedimentation tank flows to the secondary sedimentation tank; sludge generated after the sedimentation of the primary sedimentation tank and the secondary sedimentation tank enters the sludge bucket, and is discharged by a sludge guide tube so as to be treated. According to the arrangement of the secondary inclined-tube sedimentation tank provided by the utility model, a normally-used single sedimentation tank body is cut off into the primary sedimentation tank and the secondary sedimentation tank, the gradient sedimentation effect is better than the traditional inclined-tube sedimentation tank, and is beneficial to improving the sedimentation efficiency and shortening the dwell time. Additionally, even though the sewage treatment system encounters accidental situations, resulting in the pollution of the primary sedimentation tank, the water quality of the secondary sedimentation tank cannot be affected soon, so that a favorable buffer effect is achieved. The design is simple in structure, improves the water quality monitoring percent of pass, is low in cost, and is easy to popularize.

Description

A kind of secondary tube settler

Technical field

The utility model relates to sewage treatment area, specifically relates to a kind of secondary tube settler.

Background technology

Existing sedimentation basin of sewage disposal, mainly be to make short grained suspension adsorb mutually, assemble by in sewage, adding flocculant and flocculation aid, becoming big back is deposited in the bucket by the gravity effect, the time of staying that this process need is certain, therefore to hold big floor space also big in the pond, and sewage constantly enters the pond body and impacts bed mud, and the mud come-up also can influence the sedimentation effect of whole pond water body, effluent quality is reduced, therefore need carry out necessary improvement to existing sedimentation basin.

The utility model content

The utility model is big for solving present sedimentation basin floor space, and the problem that the sludge settling effect is bad provides a kind of settling efficiency height, and the time of staying is short, is difficult for contaminated sedimentation basin.

For reaching above-mentioned effect, design of the present utility model is a kind of secondary tube settler of design, mainly comprise sedimentation basin body and sludge bucket two parts, wherein, described sedimentation basin body cuts off between therefrom, constitute by primary sedimentation basin is adjacent with secondary sedimentation tank, distribution channel drains into by sparge pipe at the bottom of the pond, and distributing hole evenly is arranged on below the sparge pipe, arranges in the described primary sedimentation basin and evenly is densely covered with inclined tube, under described two sedimentation basin bodies sludge bucket is set, mud is discharged post processing by sludge pipe.

Described sedimentation basin cuts off into two parts that volume equates with cement, is respectively primary sedimentation basin and secondary sedimentation tank.

Described distribution channel base is provided with opening.

Described sparge pipe is provided with many, is arranged at the bottom of the pond side by side.

Described inclined tube is from the horizontal by the angle of inclination, and described inclined tube section has that positive hexagon is capable, rhombus, circle and square.

For the water pollution that prevents from happening suddenly influences whole sedimentation basin, further optimized technical scheme also has, and establishes valve at primary sedimentation basin between the secondary sedimentation tank distribution channel, described gate is manual regulating gate, or the Electromagnetic Control gate, is convenient to intercept fully the water body of two sedimentation basins.

For improving the deposition efficiency of sedimentation basin, further optimized technical scheme also has, and sewage drains into sedimentation basin body bottom by sparge pipe in the distribution channel, and fluid increases its come-up distance from bottom to top.

For guaranteeing sewage uniform distribution in sedimentation basin, further optimized technical scheme also has, and described sparge pipe is distributed at the bottom of the pond by the size variation radical in pond.

With the extension of sparge pipe, hydraulic pressure reduces gradually, for guaranteeing distributing hole water yield distributed uniform, need to calculate hole count and the distance of arranging accurately according to hydraulics, and non-homogeneous punching.

For the body refuse that guarantees to be deposited on the inclined tube bottom surface slips into bucket automatically by gravity, further optimized technical scheme also has, and the inclined tube inclination angle considers by whether the sliding of mud and flow direction thereof be consistent, generally gets 30 °＜α＜60 °.

For the mud come-up that the time water inlet impulsive force that reduces water distribution causes, further optimized technical scheme also has, and the distributing hole on the sparge pipe is design down without exception.

For the convenience of installing and overhauling, further optimized technical scheme also has, and many swash plates or inclined tube are prefabricated into module, and monoblock is installed in the sedimentation basin then.

The beneficial effects of the utility model are: the utility model arranges the single sedimentation basin body that the secondary tube settler will use always and cuts off into two parts, sewage precipitates in two steps, this gradient precipitation has shortened the time of staying, reduced the ill effect of mud come-up, compare with traditional sedimentation basin and to have improved deposition efficiency greatly, in addition, even unexpected situation appears in sewage disposal system, cause primary sedimentation basin contaminated, also can not have influence on the sedimentation effect of secondary sedimentation tank at once, play good cushioning effect, the design is simple in structure, and result of use is good, and the water quality monitoring qualification rate is improved, with low cost, be easy to promote.
