Embodiment
A kind of sewage water treatment method that negative suction aeration unhurried current is mixed is present embodiments provided, this method passes through jet-flow aeration and fills
Mixing arrangement of setting and flow slowly is implemented.
As shown in Figure 1, the efflux aerator includes: water inlet pipe 10, ejector 20, aeration tube 30, injecting enters
Agent pipe；It is described enter the setting of agent pipe in 20 front end of ejector, the setting of the aeration tube 30 is described in 20 rear end of ejector
Entering agent pipe by injecting sequence successively includes: modifying agent pipe 11, coagulant pipe 12, flocculant pipe 13；30 side wall of the aeration tube is opened
It is equipped with into tracheae 31, the aeration tube 30 enters tracheae 31 and air communication described in.
Shown in Fig. 2,30 rear end of the aeration tube is connected with unhurried current mixing arrangement, and the unhurried current mixing arrangement is passed through by sewage
Sequence successively includes: circular passage 40, current limiting plate 41, choked flow stick 42, outlet pipe 43；The current limiting plate 41 and the choked flow stick 42 are equal
It is fixed on 40 inner wall of circular passage, the outlet pipe 43 is provided with the unhurried current mixing device bottom center.
The sewage water treatment method successively comprises the following steps that
Injecting is added in the first step:
As shown in Figure 1, the modifying agent pipe 11 and the coagulant pipe 12 are opened, to institute when sewage passes through water inlet pipe 10
It states and injects modifying agent (such as: inorganic modified calcium) and coagulant (such as: aluminum sulfate) in sewage, the modifying agent mixes instead with sewage
It answers, to remove the BOD in sewage (COD), COD (biochemical oxygen demand (BOD)) and total phosphorus substance；The coagulant and dirt
Water hybrid reaction, to by sewage small suspended particulate and colloidal solid be condensed into larger particles；The modifying agent and institute
After stating coagulant injection, while the modifying agent pipe 11 and the coagulant pipe 12 are closed, the flocculant pipe 13 is beaten
It opens, injects flocculant (such as: polyaluminum sulfate ferric-aluminum chloride) in Xiang Suoshu sewage, the flocculant is reacted with the sewage, so that
The impurity and larger particles that sewage generates after reacting completely with the modifying agent and the coagulant are condensed into the wadding for being easy to precipitate
Solidifying body, separates convenient for subsequent filter；
Second step accelerates flow velocity:
As shown in Figure 1, the sewage for being added to injecting injects aeration tube 30 after accelerating by 20 jet stream of ejector；
Third step, aeration:
As shown in Figure 1, sewage flow at high speed in the aeration tube 30, generates strong negative pressure when by entering tracheae 31,
By air from it is described enter tracheae 31 suck in the aeration tube 10 and mix with the Sewage shock, realize the aeration of sewage, in this way
Device the aeration of sewage can be realized in the duct, occupied space is minimum, and the sewage is flowed in pipeline and be can be completed
Aeration eliminates the plenty of time for needing to spend in aeration tank aeration, is aerated ultrahigh in efficiency；
4th step, unhurried current:

The sewage after speed passes through the pipeline for being equipped with current limiting plate 41, and flow velocity further slows down；
5th step, mixing discharge:
As shown in Fig. 2, the sewage after unhurried current flows through the pipeline for being provided with choked flow stick 42, the sewage passes through the choked flow stick
Vortex is generated when 42, achievees the effect that stirring sewage is sufficiently mixed sewage with injecting and reacts, well-mixed sewage is by going out
Pipe 43 is discharged.
The sewage added with injecting first passes through efflux aerator and is sufficiently aerated, then is made by the mixing arrangement that flows slowly
The sewage is sufficiently mixed with the injecting, and such sewage water treatment method makes aeration process the space occupied small, and is aerated
Required time is short, high-efficient, while the use for the mixing arrangement that flows slowly avoids sewage and is not thorough with the purification of injecting undercompounding
The case where.
In the second step, flow velocity is not less than 0.3m/s after sewage is accelerated by the ejector 20, avoids flow velocity too low
Negative pressure deficiency causes the sewage aeration insufficient.
In the third step, it is described enter tracheae 31 be provided with it is multiple, and it is multiple it is described enter tracheae 31 be arranged at aeration tube
30 the same side, and it is described enter tracheae 31 between spacing distance be 100mm~150mm.
