Abstract
The utility model relates to a layered water distribution canal for a settling pond. The layered water distribution canal for the settling pond is simple in structure, convenient to construct, capable of improving the water distribution evenness of the settling pond, reducing the water distribution head loss and solving the problem that mud is accumulated in the water distribution canal. According to the technical scheme, the layered water distribution canal for the settling pond is arranged in the settling pond, one side of the water distribution canal is connected with a flocculating pond and communicated with the flocculating pond by a water inlet, the layered water distribution canal is characterized in that the water distribution canal is of a vertical two-layer structure, the upper layer is connected with the water inlet, and a plurality of triangular strips arranged at intervals are arranged at the bottom of the upper layer; and a plurality of water outlets are arranged at the side of the lower layer, away from the flocculating pond, the bottom surface of the lower layer is an inclined surface which is inclined towards the water outlets from the flocculating pond, and the water outlets are smoothly connected with the bottom surface of the lower layer. The layered water distribution canal for the settling pond is applicable to water distribution canals of flat flowing type settling ponds and inclined tube type settling ponds.
Description
Technical field
The utility model relates to a kind of sedimentation basin layer-stepping distributing channel.Be applicable to flat flow and tube settler distributing channel.
Background technology
The water distribution mode that horizontal sedimentation tank and tube settler are commonly used has two kinds: 1, by the water distribution weir is set in distributing channel, former water climbs over the purpose that reaches uniform water distribution after weir crest.The shortcoming of water distribution weir water distribution is that the civil engineering size is large, and the loss of flood peak is large, and employing is easily broken alumen ustum and affected treatment effect after the dosing flocculation.2, without the directly perforate on the distributing channel wall of water distribution weir, adopt the water distribution of water distribution tracery wall, this water distribution mode water channel size is little, and the loss of flood peak is little, but has the water distribution non-uniform phenomenon.Two kinds of water distribution modes all have the problem of distributing channel deposition, and traditional approach is that the regular spoil disposal of discharge pipeline is set.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, provide a kind of sedimentation basin layer-stepping distributing channel of simple in structure, easy construction, improve the sedimentation basin water distribution uniformity, reduce the water distribution loss of flood peak, and solve distributing channel deposition problem.
The technical scheme that the utility model adopts is: a kind of sedimentation basin layer-stepping distributing channel, this distributing channel is located in sedimentation basin, distributing channel one side connects flocculation basin and is communicated with through water inlet, it is characterized in that: described distributing channel is vertical double-decker, the upper strata connects described water inlet, and this layer bottom is the triangular strip that some intervals arrange; Lower floor offers some delivery ports away from the flocculation basin side, and this layer bottom surface is an inclined-plane, is rolled tiltedly described delivery port and this layer bottom surface smooth connection by flocculation basin side water exit mouth.
Described distributing channel lower floor bottom surface is provided with some clinohedrals that prevent the mud alluvial by the delivery port side, and clinohedral is between adjacent two delivery ports.
The beneficial effects of the utility model are: the utility model adopts vertical double-layer structure, therefore can not increase the size of distributing channel, saves to take up an area, reduce cost; Utilize the vertically degree of depth more than needed of distributing channel, adopt double-deck vertical water distribution system, improve the sedimentation basin water distribution uniformity, reduce the water distribution loss of flood peak, reach the water distribution effect on water distribution weir with the size of water distribution tracery wall; All adopt inclined-plane form baffle in distributing channel, solve distributing channel deposition problem.

The specific embodiment
As Fig. 1 ~ shown in Figure 5, the present embodiment is a kind of sedimentation basin layer-stepping distributing channel, and this distributing channel 3 is arranged in sedimentation basin, and a side of distributing channel connects flocculation basin 1, and distributing channel is communicated with through water inlet 2 with flocculation basin 1.In this example, distributing channel 3 adopts vertical double-deck water distribution structure, it connects water inlet 2 at the middle and upper levels, and be the triangular strip 5 that some intervals arrange in the bottom of this layer, different arrangement pitch (corresponding water inlet 2 place's spacings are 220mm, and the both sides spacing increases successively) is taked at the corresponding different position of triangular strip 5; The bottom surface of lower floor is an inclined plane, and the flocculation basin 1 side direction distributing channel opposite side inclination by distributing channel offers some delivery ports 4 on the canal wall of lower floor away from flocculation basin 1 side, and delivery port 4 and this layer bottom surface smooth connection, to solve distributing channel deposition problem.For preventing mud section alluvial between delivery port and delivery port, be provided with clinohedral 6 at this place in this example, make and originally will deposit in the water outlet gathering to clinohedral 6 both sides along the clinohedral surface of the mud at this place.
The specific works principle of the present embodiment is as follows: in flocculation basin 1, sewage flows into distributing channel 3 upper stratas through water inlet 2, and the bottom triangular strip 5 of flowing through, thereby reach the purpose that reduces the resistance water distribution uniformity, through entering distributing channel lower floor after triangular strip 5, the bottom surface that lower floor tilts should be to being horizontal flow with descent waterflow, play simultaneously the purpose of water distribution for the second time, make water distribution more even, flow out from delivery port 4 at last.Because ramp structure is adopted in the lower floor bottom surface, therefore the solid that sinks can flow out distributing channel 3 automatically along the inclined-plane, without the deposition problem, discharge pipeline need not be set.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation of making, change and add or replace, all should belong to protection domain of the present utility model.
