Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of activated sludge sedimentation device, is arranged on aeration
Pond (1), including：
Feeding cylinder (2), wastewater inlet (3), flocculant import (4) and clear water output (5) are offered in its side wall, it is described clear
The height of water out (5) is higher than the height of the wastewater inlet (3)；
Settlement barrel (6), it is vertical elongated cylinder, and the diameter of the settlement barrel (6) is less than the feeding cylinder (2)；
Accelerate cylinder (7), it is the back taper cylinder being connected between the feeding cylinder (2) and the settlement barrel (6)；
Drainage system, it includes middle rotating shaft (8) and accelerates oar (9), and the middle rotating shaft (8) is vertically arranged in the feeding cylinder
