Embodiment
As shown in Figure 1, present embodiments provide a kind of jet-flow aeration sewage-treatment plant, the device include: aeration tube 10,
Ejector 20, injecting enter agent pipe；It is described enter the setting of agent pipe in 20 front end of ejector, the aeration tube 10 is arranged in institute
State 20 rear end of ejector, it is described enter agent pipe by injecting sequence successively include: modifying agent pipe 21, coagulant pipe 22, flocculant pipe 23；
10 side wall of the aeration tube is offered into tracheae 11, and the aeration tube 10 enters tracheae 11 and air communication described in.
While sewage is by entering agent pipe, the modifying agent pipe 21 and the coagulant pipe 22 are opened, in Xiang Suoshu sewage
Modifying agent (such as: inorganic modified calcium) and coagulant (such as: aluminum sulfate), the modifying agent and sewage hybrid reaction are injected, to go
Except BOD (COD), COD (biochemical oxygen demand (BOD)) and the total phosphorus substance in sewage；The coagulant mixes instead with sewage
Answer, to by sewage small suspended particulate and colloidal solid be condensed into larger particles；The modifying agent and the coagulant
After injection, while the modifying agent pipe 21 and the coagulant pipe 22 are closed, the flocculant pipe 23 is opened, Xiang Suoshu
In sewage inject flocculant (such as: polyaluminum sulfate ferric-aluminum chloride), the flocculant is reacted with the sewage so that sewage with it is described
The impurity and larger particles that modifying agent and the coagulant generate after reacting completely are condensed into the floccule body for being easy to precipitate, after being convenient for
It is continuous to be separated by filtration.
The sewage of auxiliary agent is mixed with by injecting the aeration tube 10 after the ejector 20, the sewage is in the aeration
Flow at high speed in pipe 10, by it is described enter tracheae 11 when generate strong negative pressure, by air from it is described enter tracheae 11 suck the aeration
It is mixed in pipe 10 with the Sewage shock, realizes that the aeration of sewage can be realized in the aeration of sewage, such device in the duct,
Occupied space is minimum, and the sewage flows in pipeline that aeration can be completed, and eliminates and in aeration tank aeration needs to spend
Plenty of time is aerated ultrahigh in efficiency.
