Specific embodiment
A specific embodiment of the utility model is described in detail combined with Figure 1 and Figure 2, but not to the power of the utility model
Benefit requires to do any restriction.
As depicted in figs. 1 and 2, a kind of activated sludge aeration tank, including pond body 1, the pond body 1 are in cuboid, the pond
Body 1 is divided into sludge blanket 7 and the buffer layer 8 above sludge blanket 7 by horizontally disposed partition 6, and is provided on partition 6
Through-hole, for being connected to sludge blanket 7 and buffer layer 8, a upper inside wall of the pond body 1 is provided with overflow launder 9, and lower part is provided with
Inlet, and inlet is located at the lower section of partition 6, overflow launder 9 is located above partition 6, the inlet be connected with water pump 3 into
Liquid pipe 2, and inlet tube 2 is located at the outside of pond body 1, air hose 5 is connected between the inlet and water pump 3, and in air hose 5
