Description
Technical field
The present invention relates to technical field of sewage, in particular to a kind of aeration tank polycrystalline substance.
Background technology
In the sewage disposal of activated sludge process, aerobic aeration pond is a very important process section, and the aeration tank is
The structures of sewage disposal are carried out using activated sludge process.Certain dwell time of sewage is provided in pond, aerobic microbiological institute is met
The mixing condition that the oxygen amount and sewage of needs are fully contacted with activated sludge.Aeration tank mainly by pond body, aerating system and is entered
Three parts of delivery port constitute.Pond body is typically built up with armored concrete, and flat shape has rectangle, square and circular etc..
Existing aeration tank bottom bottom surface and its side shape right angle in 90 °, then cause aeration tank bottom and aeration tank side
The place of junction is easily created aeration blind area, so in the case where long-time is aerated, the aeration blind area can gather non-
Often many aerobic activated sludges, if these activated sludge cannot get enough dissolved oxygens, then these aerobic activated sludge are then
The activated sludge of anaerobism can be become, and the condition is unsatisfactory for the life condition of microorganism in anaerobic activated sludge, then these are exhausted
The anaerobic activated sludge of big department will be inactivated, and become dead mud and floated, and cause sewage aeration insufficient, make the expense for the treatment of sludge
Raise.
The content of the invention
It is a primary object of the present invention to provide aeration tank polycrystalline substance, formed with solving aeration tank bottom in the prior art
Aeration blind area causes aeration insufficient, is aerated the increased problem of cost.
To achieve these goals, there is provided a kind of aeration tank polycrystalline substance, the aeration tank polycrystalline substance is included by bottom surface
The aeration tank polycrystalline substance main body surrounded with side, the aeration head for being arranged at bottom surface, the bottom of the aeration tank polycrystalline substance main body
Face is provided with air-flow buffer structure with side joint.When starting aeration inside aeration tank, air-flow buffer structure is to entering
Air-flow to bottom surface and side joint plays cushioning effect, causes it while direction is changed, the energy of loss compared to
Common aeration tank before can also greatly reduce, and due to the increase of current rate, the activated sludge in the region is difficult to pile up, and
Activated sludge in aeration tank before can be more abundant compared with the degree that pending waste water mixes.Under identical aeration rate,
Using aeration tank of the invention to the utilization rate of tolerance higher than common aeration tank, aeration is more abundant, its dead sludge for producing
More common aeration tank will be lacked, Treatment of Sludge operating cost step-down.
Further, the air-flow buffer structure includes being arranged at the concave Iy curved structure of bottom surface and side joint.By
This, when the air-flow of aeration meets the concave Iy curved structure, concave Iy curved structure plays a part of above-mentioned buffering to air-flow.
Further, arc of the concave Iy curved structure including covering bottom surface with side joint, the arc,
A confined space is constituted between bottom surface, side.Thereby, it is possible to realize above-mentioned concave Iy curved structure, and simple structure, realize
Get up to be easier.
Further, the concave Iy curved structure also includes the supporting construction of support arc.As a result, arc
Mounting structure is more stablized.
Further, the supporting construction includes being filled in the concrete structure of confined space.Thus, it is fully filled close
Space is closed, the more stable effect of arc board mounting structure is reached.When arc is also adopted by concrete structure, supporting construction with
The concrete structure that arc holds together.
Further, the distance between the upper edge of the arc and described bottom surface and arc lower edge with it is described
The distance between side is the half of the distance between the nearest aeration head of arc and the side.By practical study table
It is bright under this condition, concave Iy curved structure is optimal for aeration gas flow buffering effect.
Further, the radian of the arc is 30 ° -45 °.Show under this condition by practical study, matrix is bent
Face structure is preferable for aeration gas flow buffering effect.
Further, the radian of the arc is 45 °.Show under this condition by practical study, concave Iy curved knot
Structure is optimal for aeration gas flow buffering effect.
Further, the aeration tank polycrystalline substance main body is square body, and the concave Iy curved structure setting is in square body
The front and rear and/or left and right sides.Thus, concave Iy curved structure can be arranged on different several positions of aeration tank polycrystalline substance main body
Put, aeration gas flow is buffered with realizing various ways.
It can be seen that, under identical aeration rate, the utilization rate of tolerance is exposed higher than common aeration tank using aeration tank of the invention
Gas is more abundant, and also more common aeration tank will be lacked the dead sludge that it is produced, and Treatment of Sludge running cost is substantially reduced.
The present invention is described further with reference to the accompanying drawings and detailed description.The additional aspect of the present invention and excellent
Point will be set forth in part in the description, and partly will become apparent from the description below, or by practice of the invention
Solve.
