Description
[technical field]
This utility model relates to a kind of Aeration tank, is specifically related to one and is thoroughly mixed formula Aeration tank discharging device, belongs to technical field of sewage treatment equipment.
[background technology]
In activated sludge water treatment system, according to the difference of reactor, the fluidised form of water can be divided into pulling flow type, be thoroughly mixed formula and conjunction type three major types.In actual applications, they have respective advantage and feature.
It is thoroughly mixed formula Aeration tank because its floor space is less, little for influent quality influence of fluctuations, strong shock resistance, it is adapted to the process of industrial wastewater.In pond, each point situation is identical, all can control completely in good or optimal state.
But, the Aeration tank of prior art is due to the sedimentation on ground, and the liquid level water outlet causing Aeration tank top is uneven, even occurs in that monolateral or a bit of circular arc, in water outlet, causes the water outlet in Aeration tank that short flow phenomenon occurs.
Therefore, for solving above-mentioned technical problem, necessary offer one is thoroughly mixed formula Aeration tank discharging device, to overcome described defect of the prior art.
[utility model content]
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of effective, the formula that the is thoroughly mixed Aeration tank discharging device of low cost
For achieving the above object, the technical scheme that this utility model is taked is: one is thoroughly mixed formula Aeration tank discharging device, and it includes Aeration tank, aerator, water inlet pipe, water leg, some galvanized pipes, outfall sewer, water outlet baffle plate and effluent trough；Wherein, described aerator is arranged on the bottom of Aeration tank；Described water inlet pipe is inserted vertically into the central authorities of Aeration tank；Described water leg is arranged on the top in Aeration tank；Described some galvanized pipes are the most uniformly connected to water leg, which is provided with outlet, and the outlet of each galvanized pipe is contour；Described outfall sewer is connected to the bottom of water leg；Described water outlet baffle plate is arranged on the upside of Aeration tank；Described effluent trough is arranged on outside water outlet baffle plate, and it is higher than water outlet baffle plate.
The formula Aeration tank discharging device that is thoroughly mixed of the present utility model is further arranged to: described galvanized pipe is specially 6, its a size of DN40；Described outfall sewer a size of DN80.
The formula Aeration tank discharging device that is thoroughly mixed of the present utility model is further arranged to: described zinc-plated end 90-degree bent straight up, and kink height is 10cm.
The formula Aeration tank discharging device that is thoroughly mixed of the present utility model is also configured to: described water leg is arranged on the central authorities of Aeration tank.
Compared with prior art, this utility model has the advantages that
Discharging device the most of the present utility model, material is simple, can cut in advance and weld, then the scene of taking is put in Aeration tank inside maintenance shop.
2. simple in construction, the water in Aeration tank enters into the dust-collecting bucket of centre by the zinc-plated mouth of pipe of six DN40, then is flowing into second pond by the galvanized pipe of a DN80 bottom dust-collecting bucket.
3. plant running is stable, owing to the height of outlet can regulate, when liquid level one timing in Aeration tank, the galvanized pipe mouth of pipe height of six ND40 of regulation, so that it may so that the mouth of pipe just submergence liquid level, it is ensured that on six same horizontal planes of the mouth of pipe.
4. installation cost is low, the most again the ground bottom Aeration tank is carried out concreting, and its quantities and engineering time the most greatly reduce.
5., after using device of the present utility model, not only prevent the short flow phenomenon of generation so that the water outlet of six mouths of pipe is uniform, and has stopped bottom effluent trough, the phenomenon that activated sludge accumulates in a large number occurs.
[accompanying drawing explanation]
Fig. 1 is of the present utility model to be thoroughly mixed formula Aeration tank discharging device schematic diagram.
[detailed description of the invention]
Referring to shown in Figure of description 1, the formula Aeration tank discharging device that is thoroughly mixed of the present utility model is made up of several parts such as Aeration tank 4, aerator 5, water inlet pipe 1, water leg 8, some galvanized pipes 9, outfall sewer 2, water outlet baffle plate 3 and effluent troughs 7.
Wherein, described aerator 5 is arranged on the bottom of Aeration tank 4.Described water inlet pipe 1 is inserted vertically into the central authorities of Aeration tank 4.Flow in Aeration tank 4 by 1 industrial wastewater of water inlet pipe, after the oxygen supply and stirring of aerator 5 so that the quick mix homogeneously of muddy water in Aeration tank 4.
Described water leg 8 is arranged on the top in Aeration tank 4.Described water leg 8 is arranged on the central authorities of Aeration tank 4.
Described some galvanized pipes 9 are the most uniformly connected to water leg 8, which is provided with outlet 91, and the outlet 91 of each galvanized pipe 9 is contour, so prevents short flow phenomenon, causes some regions not have water outlet for a long time.Described galvanized pipe 9 is specially 6, and its a size of DN40, its end 90-degree bent straight up, kink height is 10cm.
Described outfall sewer 2 is connected to the bottom of water leg 8, its a size of DN80.When Aeration tank liquid level 6 submergence outlet 91, by the outlet 91 of galvanized pipe 9, enable them to uniform water outlet.Finally, interfluent dust-collecting bucket 8, total outlet pipe 2 of the DN80 through bottom, flow in second pond.
Described water outlet baffle plate 3 is arranged on the upside of Aeration tank 4；Described effluent trough 7 is arranged on outside water outlet baffle plate 3, and it is higher than water outlet baffle plate 3.
It is of the present utility model that to be thoroughly mixed formula Aeration tank discharging device carrying out practically method as follows:
1), by industrial wastewater by water inlet pipe 1, circular Aeration tank 4 is entered, through being thoroughly mixed the reaction of formula so that the activated sludge in Aeration tank carries out with industrial wastewater sufficient mixing homogeneously, and the time of staying of Aeration tank has 37 hours；
2), the liquid level 6 of Aeration tank controls all the time between outlet 91 and water outlet baffle plate 3.This way it is ensured that the mixed liquor in Aeration tank, effluent trough 7 will not be entered by water outlet baffle plate；
3), adjusting galvanized pipe outlet 91 height of six DN40, the liquid level 6 of Aeration tank can submergence outlet.Meanwhile, the height of six mouths of pipe can be adjusted, it is ensured that the inflow of each mouth of pipe is of substantially equal, it is ensured that water outlet uniformity and seriality；
4), after the galvanized pipe of DN40, converge to middle water leg 8, the more total outlet pipe of DN80 2 bottom water leg, enter second pond.
After this utility model discharging device being installed in hybrid Aeration tank, six outlet stable water outlet, continuous and uniform, do not block.Effectively solve Aeration tank water outlet uneven, avoid the generation of short stream as far as possible, improve aeration section and remove the ability of COD.
Above detailed description of the invention is only the preferred embodiment of this creation, and not in order to limit this creation, all any modification, equivalent substitution and improvement etc. done within this spirit created and principle, within should be included in the protection domain of this creation.
