After object mortality, fluviatic ecosystem destruction is irrigated with contaminated river, then plant, crops also can be by
To influence, it is easy undergrowth, and people can not feeding these crops.Therefore, it is necessary to COD processing in all kinds of waste water
Reach discharge standard, wherein main minimizing technology is exactly to utilize biological aerated filter, organic dirt in waste water can be effectively removed
Object is contaminated, biological aerated filter needs mating a large amount of aerator and pipeline, it is usually required mainly for configures more Aeration fan, causes
Waste water disposal facility construction, operation cost are higher.
Invention content
The utility model in order to overcome the shortcomings of the above technology, provide it is a kind of to waste pipe using original pressure to useless
Water carries out automatic flow aeration, cost-effective waste water automatic flow aerator.
Technical solution is used by the utility model overcomes its technical problem：
A kind of waste water automatic flow aerator, including：
Shell, both ends open, surrounding is closed, and water inlet is formed at front opening, and its rear end opening forms water outlet
Mouthful；
Nozzle, sealing are plugged in housing forward end water inlet, and the air-breathing of annular is formed between outer nozzle wall and inner walls
Chamber；
Air inlet pipeline is installed on shell, and lower end is connected with suction muffler, and the upper end is equipped with air inlet adjustment valve；
Distribution device is set in suction muffler, and it is located at the front end of jet expansion；
Waste water delivery pump, outlet are connected by pipeline with nozzle；And
Wastewater disposal basin is connected by pipeline with water outlet；
The inside of shell between the jet expansion and water outlet forms mixing chamber.
In order to make flow accelerate, said nozzle is pyramidal structure, along water inlet on water outlet direction internal diameter by becoming greatly
It is small.
In order to facilitate observation aerating wastewater effect, observation window is provided on the shell of above-mentioned water outlet.
Further include being set to isolating valve I between waste water conveying pump discharge and nozzle on pipeline, setting in order to facilitate maintenance
Isolating valve II and bypass valve between wastewater disposal basin and water outlet on pipeline, described bypass valve one end convey pump discharge with waste water
It is connected, the other end is connected with wastewater disposal basin.
The utility model has the beneficial effects that：Waste water is pumped into nozzle and gone out by waste water delivery pump, and waste water sprays after flowing through nozzle
Enter mixing chamber, it, can be from air inlet pipe by adjusting air inlet adjustment valve to generate negative pressure in suction muffler since water flowing acts on
Air is sucked in road, air is sufficiently mixed with waste water at mixing chamber, and to complete to be aerated, treated waste water is from water outlet stream
Enter wastewater disposal basin.By the aeration to waste water, the COD contents in waste water are further decreased, without in addition providing electric energy in operation, are reached
To energy-saving purpose.

Specific implementation mode
Below in conjunction with the accompanying drawings 1, attached drawing 2 is described further the utility model.
A kind of waste water automatic flow aerator, including：Shell 1, both ends open, surrounding is closed, shape at front opening
At water inlet 2, its rear end opening forms water outlet 10；Nozzle 3, sealing is plugged at 1 front end water inlet 2 of shell, outside nozzle 3
The suction muffler 6 of annular is formed between 1 inner wall of wall and shell；Air inlet pipeline 4 is installed on shell 1, lower end and 6 phase of suction muffler
Connection, the upper end is equipped with air inlet adjustment valve 5；Before distribution device 7 is set in suction muffler 6, and it is located at the outlet of nozzle 3
End；Waste water delivery pump 11, outlet are connected by pipeline with nozzle 3；And wastewater disposal basin 15, pass through pipeline and 10 phase of water outlet
Even；The inside that nozzle 3 exports the shell 1 between water outlet 10 forms mixing chamber 8.Waste water is pumped into nozzle by waste water delivery pump 11
3 go out, and waste water spurts into mixing chamber after flowing through nozzle 3, since water flowing acts on, to generate negative pressure in suction muffler 6, pass through tune
Section air inlet adjustment valve 5 can suck air from air inlet pipeline 4, and air is sufficiently mixed with waste water at mixing chamber 8, to complete
Aeration, treated, and waste water flows into wastewater disposal basin 15 from water outlet 10.By the aeration to waste water, further decrease in waste water
COD contents achieve the purpose that energy-saving without in addition providing electric energy in operation.
