Description

A kind of circumferential water feed type sedimentation basin of sewage disposal
Technical field
The utility model belongs to sewage treatment area, more particularly, to a kind of circumferential water feed type sedimentation basin of sewage disposal.
Background technology
Sedimentation basin is the chief component of activated sludge sewage disposal technology, the suspension being generally used in sewage or work Property sludge settling get off, reached clarification water quality purpose.Typically points three kinds of sedimentation basin, i.e. flat flow, radial-flow and vertical-flow.
Radical sedimentation basin is generally divided into center water inlet peripheral effluent, circumferential water feed center according to water-in and water-out arrangement Three kinds of water outlet and circumferential water feed peripheral effluent.Because the outlet effect of circumferential water feed formula sedimentation basin is preferable, by increasing work Cheng Caiyong.But the design method for arrangement of being intake to circumferential water feed formula radial flow tank still lacks clear and definite, specific specification at present, if Timing has very big randomness, often causes water distribution uneven, influences treatment effect, can not embody the superiority of circumferential water feed.
The content of the invention
The purpose of this utility model is solve deficiency of the prior art, there is provided a kind of circumferential water feed type sewage disposal is sunk Shallow lake pond, sedimentation effect can be effectively improved, reduce the water outlet concentration of suspension of sedimentation basin.
In order to solve the above technical problems, the technical solution adopted in the utility model is:A kind of circumferential water feed type sewage disposal Sedimentation basin, including sedimentation basin pond body, secondary sedimentation tank is provided with the outside of the sedimentation basin pond body and receives pond, it is described secondary heavy The height in shallow lake pond is less than the sedimentation basin pond body, the outside received pond and be arranged on the secondary sedimentation tank, the sedimentation basin The upper base surface of pond body is mud collection area, and the central area of the mud collection area is provided with sludge bucket, set in the sludge bucket side wall Discharge pipeline is equipped with, the sedimentation basin pond body bottom is additionally provided with water inlet pipe, and the water inlet pipe passes through the sedimentation basin pond body and institute State secondary sedimentation tank placement.
Further, the central part of the sedimentation basin pond body is provided with V-groove, and the V-groove is fixed on institute by floor State the central part of sedimentation basin pond body.
Further, the hypotenuse of the V-groove and vertical direction angle are 30 ° -60 °.
Further, mud scraper is additionally provided with the sedimentation basin pond body, the mud scraper stretches to the sedimentation basin pond The bottom of body, the cleaning shoe corresponding with the mud collection area is provided with the mud scraper.
Further, it is provided with triangle weir plate between the receipts pond and the secondary sedimentation tank.
The utility model has the advantages and positive effects of:Due to using above-mentioned technical proposal, can effectively improve Sedimentation effect, reduce the water outlet concentration of suspension of sedimentation basin;And there is simple in construction, applied widely, operation maintenance convenience, The advantages that sedimentation effect is good, water outlet is more stable.

Embodiment
The utility model is described further with reference to the accompanying drawings and examples.
As shown in figure 1, the present embodiment provides a kind of circumferential water feed type sedimentation basin of sewage disposal, including sedimentation basin pond body 4, sink The outside of shallow lake pond pond body 4 is provided with secondary sedimentation tank 3 and receives pond 2, and the height of secondary sedimentation tank 3 is less than sedimentation basin pond body 4, receives Pond 2 is arranged on the outside of secondary sedimentation tank 3, and the upper base surface of sedimentation basin pond body 4 is mud collection area 12, the center of mud collection area 12 Region is provided with sludge bucket 10, and discharge pipeline 11 is provided with the side wall of sludge bucket 10, and the bottom of sedimentation basin pond body 4 is additionally provided with water inlet pipe 1, water inlet pipe 1 is placed through sedimentation basin pond body 4 and secondary sedimentation tank, is received and is provided with triangle between pond 2 and secondary sedimentation tank 3 Weir plate 8.
The central part of sedimentation basin pond body 4 is provided with V-groove 6, and V-groove 6 is fixed in sedimentation basin pond body 4 by floor 7 Center portion, hypotenuse and the vertical direction angle of V-groove 6 are 30 ° -60 °.
It is additionally provided with mud scraper 5 in sedimentation basin pond body 4, mud scraper 5 stretches to the bottom of sedimentation basin pond body 4, on mud scraper 5 It is provided with the cleaning shoe 9 corresponding with mud collection area 12.
The course of work of this example:As shown in Fig. 2 in use, waste water enters pond in sedimentation basin pond body 4 by water inlet pipe 1 At a points near bottom, into sludge compression layer I, for this layer of sludge than great, stability is good, filter bed can be used as to carry out waste water Filtering, to ensure the good filter effect of sludge compression layer, every time by be connected with sludge bucket 10 11 spoil disposal of discharge pipeline when should not It is emptied completely, remains the certain altitude of sludge compression layer I in sedimentation basin;Waste water enters layered sink after passing through sludge compression layer I Shallow lake layer II, sludge flco is larger in the layer, and concentration is higher, mutually support, can play absorption to the flco in waste water and net catches Effect;Waste water continues to flow up, and into flocbed III, due to the stop of V-groove 6, from c points into the flow process of d points, cuts Area reduces, and speed increase, direction change, and flco is separated from water, while the waste water around b points supplements rapidly to c points, in c points Neighbouring waterpower mixing enhancing, be advantageous to the growth of fine particle, enter the layered beds of precipitation II by Action of Gravity Field after flco increase, Clear water then enters clear water layer IV, and when sedimentation basin clear water overflows into secondary sedimentation tank 3, clear water carries out two in secondary sedimentation tank 3 Secondary precipitation, the clear water in final secondary sedimentation tank 3, which overflows into, receives pond 2.
The beneficial effects of the utility model are:Due to using above-mentioned technical proposal, can effectively improve sedimentation effect, drop The water outlet concentration of suspension of low sedimentation basin;And applied widely with simple in construction, operation maintenance is convenient, sedimentation effect is good, The advantages that water outlet is more stable.
One embodiment of the present utility model is described in detail above, but the content is only of the present utility model Preferred embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.It is all to be made according to present utility model application scope Equivalent change with improve etc., all should still belong within patent covering scope of the present utility model.
