Description
Technical field
The invention belongs to sewage treatment field, and in particular to a kind of sewage-treatment plant.
Background technology
With the growth of China's urban population, the domestic consumption in city is also more and more, and city domestic sewage is main
It is to be made of kitchen, lavatory flushing, shower, laundry water etc., containing many solid matters in sewage, to sanitary sewage
Before processing is carried out, sanitary sewage can generally be filtered, the processing of next step is then being carried out to sewage.Contain at the same time in sewage
Some organic nitrogen and ammonia nitrogen, are mainly derived from discarded object such as excrement of protein metabolism in human body food etc., containing in sewage
Substantial amounts of organic nitrogen and ammonia nitrogen become China's municipal water primary pollution source, if it is not purified be just discharged into river, lake and
Pollute natural water and surrounding environment；Substantial amounts of sewage directly discharges, and not only breaks up ecology, the also serious life for endangering industrial or agricultural
Production and the health and safety of the mankind.
At present now, some equipment for handling city domestic sewage are all some large and medium-sized water treatment facilities, have investment it is big,
Take up a large area, the features such as operating cost is high, a series of filtration apparatuses, ammonia nitrogen handling arrangement, settler is usually used
Combination, the circulation of water process is slower, too high for some small-scale cost of sewage disposal, and it is small can not to adapt to city domestic sewage
Scale quickly handles the needs of development.
The content of the invention
The invention is intended to provide a kind of sewage-treatment plant, quickly to be handled small-scale sewage.
In order to achieve the above object, base case of the invention is as follows：A kind of effluent cycle processing method, including process cartridge

Fixed connection, the upper end of mandril and the lower face point contact of rotation axis, rabble level are fixedly mounted on the middle part of spring.
The principle of base case：During operation, sewage and aerobic bacteria solution are passed through into accommodating chamber, sewage and aerobic bacteria are molten
Liquid is impacted on blade by inlet opening, and blade drives rotation axis to rotate, while the impurity in sewage can be through blade
Strainer, realizes the filtering to dirty impurities in water, can effectively reduce the amount of dirty impurities in water, and the processing of sewage can be imitated
Rate；Aerobic bacteria solution can further decompose the impurity in sewage at the same time.
At the same time when being added to sewage and aerobic bacteria solution in process cartridge, when rotation axis rotates, the lower face of rotation axis with
Constantly change occurring for the height of the contact point of mandril, so mandril constantly rise under the action of the spring thrust and under
Drop, during mandril raising and lowering, be fixed on the rabble on spring also in raising and lowering, and then rabble is to processing
Sewage in cylinder is constantly stirred, and aerobic bacteria solution can sufficiently be mixed with sewage, while can increase oxygen in sewage
The content of gas, and then the impurity that allows in sewage or nutriment are decomposed fully and quickly.
Sewage after processing is discharged from water outlet.
The advantages of base case：1st, inlet opening is respectively positioned on the top of strainer, and leaf is flowed to easy to sewage and aerobic bacteria solution
On piece, blade is subject to the impact force of sewage and aerobic bacteria solution, and then blade can drive rotation axis to rotate, and realize and move fluid
Mechanical energy can be converted into, realizes making full use of for energy；2nd, the lower end of rotation axis is waveform section, the upper end of bar and rotation axis
Lower face point contact, when rotation axis rotates, the horizontal level of mandril can change, and then to the lower pressure change of spring, bullet
Drive rabble to move up and down during spring length change, the same of sewage and aerobic bacteria solution is being added into process cartridge
When, the mixed liquor of sewage and aerobic bacteria solution is sufficiently stirred, increases the oxygen content in mixed liquor, improves sewage disposal effect
Rate；Rotatory force of rotation axis is converted for the pressure to mandril during this, realizes making full use of for kinetic energy；3rd, under rotation axis
End is equipped with groove, and the upper end of fixing axle is located in groove, and the upper end of fixing axle can be spacing to the progress of the lower end of rotation axis, allows rotation
Axis can keep stable rotation, the stirring for allowing rabble to stablize mixed liquor；4th, strainer is fixedly connected with blade, strainer
It is connected with the inner wall rotary seal of process cartridge, can effectively ensures that sewage can greatly reduce dirty sufficiently by strainer filtering
The content of solid impurity in water, improves sewage treating efficiency.
In conclusion being equipped with filter mechanism and rabbling mechanism in the present apparatus, the strainer in filter mechanism can be in sewage
Impurity is fully filtered, and the rotation axis in filter mechanism can link with the mandril in rabbling mechanism, allow rabble intaking
During sewage and aerobic bacteria solution are stirred, improve the degree of mixing of sewage and aerobic bacteria solution, increase sewage is become reconciled
Dissolved oxygen amount in oxygen bacterium solution, improves the treatment effeciency of sewage, and then can realize and small-scale sewage is quickly handled.
