Abstract
The utility model relates to an aeration device comprising an aeration tank. The aeration device is characterized in that the aeration tank is internally provided with an impeller; the impeller is arranged at the bottom of the aeration tank and is used for driving liquid in the aeration tank to circularly flow from the center to the upper part of the aeration tank and then from the upper part to the lower part along the wall of the aeration tank; the bottom of the aeration tank is provided with two horizontal air inlet pipes; air outlets of the horizontal air inlet pipes are located below the impeller. The aeration device has the beneficial effects of no blockage phenomenon, high oxygen supply quantity and low cost.
Description
Technical field
The utility model relates to technical field of sewage, particularly a kind of aerating apparatus.
Background technology
Aerator is the important component part in sewage disposal process by activated sludge process system, by aerator to aeration tank oxygen supply, aerator also has the function of mix and blend simultaneously, to strengthen the mass transfer condition of pollutent in water treatment system, improves treatment effect.Aeration method mainly contains following several: 1, blast aeration; 2, mechanical aeration.The general aerator or the aeration tube that are provided with micropore of adopting of blast aeration, this aerating apparatus easily stops up, and the pipeline mistake using, and cost is higher, the oxygen-supplying amount deficiency of aeration.Mechanical aeration is also referred to as surface aeration, and mechanical aerator mainly with the impeller twirl that is contained in the aeration tank water surface, carries out top layer oxygenation greatly, this aeration mode, and oxygen supply is inhomogeneous, is unfavorable for removing surperficial bubble face and suspended substance.
Summary of the invention
The technical problems to be solved in the utility model is, a kind of choking phenomenon, oxygen-supplying amount is large, cost is low aerating apparatus of can not occurring is provided.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of aerating apparatus, comprise aeration tank, it is characterized in that: in described aeration tank, be provided with impeller, this impeller is arranged on the bottom of aeration tank, impeller drive liquid in aeration tank by the mediad of aeration tank then along the downward circulation of aeration pool wall; Bottom, aeration tank is provided with two horizontal inlet pipe, and the air outlet of horizontal inlet pipe is positioned at impeller below.
Further, described aeration tank is connected with water inlet pipe, and the water outlet of this water inlet pipe is positioned at the bottom of aeration tank.
The water outlet of described water inlet pipe is positioned at impeller below.
The utility model arranges impeller in aeration tank, and the water outlet of the air outlet of inlet pipe and water inlet pipe is arranged on to impeller below, when wheel rotation, drive oxygen and sewage upwards to be flowed along center, aeration tank by bottom, aeration tank, and sewage and oxygen are carried out to mix and blend.After sewage and oxygen mix, under the acting in conjunction of coagulating agent, flocculation agent, produce a large amount of suspended substances, and then form suspended substance floc sedimentation, under the effect floating life of bubble population, suspended substance floc sedimentation and foreign material form scum silica frost, scum silica frost floats to the aeration tank water surface, utilizes slag scraper that it is separated from water.Because impeller forms a kind of suction in the time rotating, by inhaling on the air of impeller below and sewage, then stir.So the horizontal inlet pipe air outlet of impeller below can not be stopped up, and does not need cleaning.Sewage and oxygen are directly uniformly mixed, and sewage mixes with oxygen, and oxygen-supplying amount is large, is conducive to the chemical reaction in aeration tank.As long as the utility model arranges once passable to two inlet pipe outlets, little by pipe amount, cost is low.
In sum, the utlity model has choking phenomenon, oxygen-supplying amount is large, cost is low beneficial effect can not occur.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of aerating apparatus, comprises aeration tank 1, in described aeration tank 1, is provided with impeller 2, and this impeller 2 is arranged on the bottom of aeration tank 1, impeller 2 drive liquid in aeration tank by 1 mediad of aeration tank then along the downward circulation of aeration pool wall 1a; 1 bottom, aeration tank is provided with two horizontal inlet pipe 3, and the air outlet 3a of horizontal inlet pipe 3 is positioned at impeller below.Described aeration tank 1 is connected with water inlet pipe 4, and the water outlet 4a of this water inlet pipe 4 is positioned at the bottom of aeration tank 1.The water outlet 4a of described water inlet pipe 4 is positioned at impeller 2 belows.
Claims (3)
1. an aerating apparatus, comprises aeration tank, it is characterized in that: in described aeration tank, be provided with impeller, this impeller is arranged on the bottom of aeration tank, impeller drive liquid in aeration tank by the mediad of aeration tank then along the downward circulation of aeration pool wall; Bottom, aeration tank is provided with two horizontal inlet pipe, and the air outlet of horizontal inlet pipe is positioned at impeller below.
2. aerating apparatus according to claim 1, is characterized in that: described aeration tank is connected with water inlet pipe, and the water outlet of this water inlet pipe is positioned at the bottom of aeration tank.
