Technical staff better understand and use this sedimentation basin.Although the utility model can describe many details, these are not
It should be interpreted to claimed utility model or can be limited with the range of claimed utility model, but
The description of specific characteristic as specific embodiment.In certain spies of the described in this document of the context of separate embodiments
Sign, can also combine realization in a single embodiment.On the contrary, the various spies described in the context of single embodiment
Sign can also individually or with any suitable sub-portfolio be realized in various embodiments.Furthermore although above can will be special
Sign is described as in certain combinations described in effect and even initial scope of the claims, but in some cases can be from
Delete one or more features in required combination, and claimed combination can be for sub-portfolio or sub-portfolio
Variation.Similarly, although describing to operate with certain order in the accompanying drawings, this is understood not to this and is required shown in
Certain order or order in order execute such operation, or it is understood that this is required to execute all behaviour shown
Make to realize desired result.
Basic conception according to the present utility model, it is shown referring to Fig.1, a kind of vertical sedimentation tank is provided, including: pond
Body；Water inlet central tube 1, is set at the center upper portion of pond body, vertically flows into for muddy water；Under horn mouth 2, with water inlet central tube 1
End connection, and opening opens up downward；The design parameter of central tube 1 and horn mouth 2 is consistent with traditional sedimentation basin.
