Abstract
The utility model relates to an effluent trough of a sedimentation tank with distributed and improved opening holes or weirs. The effluent trough comprises a sedimentation tank 1 and an effluent trough 2, wherein, a small quantity of effluent holes or weirs are merely arranged in a certain scope at the rear end of the effluent trough or at the rear end of the sedimentation tank. The certain scope is from 1 to 2 m. The quantity of the effluent holes or the weirs is from 1 to 5. The effluent trough adopts a perforating finger-shaped trough or a triangular weir finger-shaped trough. The effluent trough solves the deficiencies that the water flow perturbation and the turbulent flow occur at the rear and of the effluent finger-shaped trough, the inundated sea spray is stirred, and the quality of effluent water is affected.
Description
Technical field
The utility model relates to a kind of water treatment building sedimentation basin effluent trough.
Background technology
It is finger type effluent trough that existing horizontal sedimentation tank or flat flow combine pond type effluent trough with other form sedimentation basins, adopts uniform triangular-notch weir or uniform orifice outflow on the effluent trough.Perforation refers to that type groove or triangular-notch weir refer to that the perforate of type groove or weir are uniform on the finger type groove.Because the current effect of inertia produces certain flow rate, the bump pool wall produces the disturbance turbulent flow, stirs alumen ustum, influences effluent quality.The present invention improves for solving this deficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of perforate or the weir improved sedimentation basin effluent trough that distributes, and it has solved the sedimentation basin water outlet and has referred to type groove rear end current disturbance turbulent flow, stirs alumen ustum, influences the deficiency of effluent quality.
The purpose of this utility model is achieved in that
A kind of perforate or the weir improved sedimentation basin effluent trough that distributes, it comprises: in the effluent trough rear end is the terminal certain limit of sedimentation basin, a small amount of apopore or weir only are set.
Described certain limit is 1～2m.Described is 1～5 on a small quantity.Described effluent trough refers to that for perforation type groove or triangular-notch weir refer to the type groove.
The utility model has following advantage and good effect:
The sedimentation basin of employing this patent design can effectively prevent because the alumen ustum come-up of the effluent trough end that the effect of waterpower plug-flow causes influences effluent quality, can prevent the terminal scum silica frost delay that the weir may cause of not establishing again.Effluent quality is good.
Description of drawings
Fig. 1 refers to the profile of type groove embodiment for the utility model orifice outflow.
Fig. 2 refers to the profile of type groove embodiment for the utility model triangular-notch weir.
The specific embodiment
Describe the utility model in detail below in conjunction with drawings and Examples.
As shown in the figure,
The direction of arrow is represented among the figure: water (flow) direction, L represents among the figure: the effluent trough rear end is the terminal certain limit of sedimentation basin.
A kind of perforate or the weir improved sedimentation basin effluent trough that distributes, it comprises: sedimentation basin 1, effluent trough 2 in the effluent trough rear end is the terminal certain limit of sedimentation basin, only are provided with a small amount of apopore or weir.
Described certain limit is 1～2m.Described is 1～5 on a small quantity.Described effluent trough refers to that for perforation type groove or triangular-notch weir refer to the type groove.
Claims (4)
1. perforate or the weir improved sedimentation basin effluent trough that distributes, it comprises: sedimentation basin (1), effluent trough (2) is characterized in that: in the effluent trough rear end is the terminal certain limit of sedimentation basin, a small amount of apopore or weir only are set.
2. perforate according to claim 1 or the weir improved sedimentation basin effluent trough that distributes, it is characterized in that: described certain limit is 1～2m.
3. perforate according to claim 1 or the weir improved sedimentation basin effluent trough that distributes, it is characterized in that: described is 1～5 on a small quantity.
4. perforate according to claim 1 or the weir improved sedimentation basin effluent trough that distributes is characterized in that: described effluent trough refers to that for perforation type groove or triangular-notch weir refer to the type groove.
