Flexible pipe;Described waste water treatment box is provided with sewage inlet, and treatment sewage imports in waste water treatment box by described sewage inlet, institute
State and in waste water treatment box, be provided with the shaft being made axial-rotation by Motor drive, described waste water treatment box bottom is provided with sewage draining exit,
Described waste water treatment box side wall is provided with the first outlet;Described first outlet connects the first flexible pipe, turns on through the first flexible pipe
To settlement of sewage case;It is provided with the filtrate bed of material, described settlement of sewage bottom portion is provided with the second water outlet in described settlement of sewage case
Mouthful;Described second outlet connects the second flexible pipe, is conducted in sewage purifier through the second flexible pipe;Set in described sewage purifier
There is light-transmission tube, in described light-transmission tube, be provided with uviol lamp, described sewage purifier bottom is provided with water purification discharge outlet, described water purification draining
Mouth is provided with drain valve.
By using this technical scheme: extraneous sewage initially enters in waste water treatment box, in the Stirring of shaft
Under effect, the bulky grain mud in sewage gradually sinks and is discharged by sewage draining exit and more clear aqueous rise from the first outlet through the
One flexible pipe enters in settlement of sewage case.Little particle Organic substance in aqueous is kept here by filtration through the described filtrate bed of material, and clear
Water passes through the second outlet and enters in sewage purifier through the second flexible pipe, eliminates the antibacterial and micro- in clear water under uv irradiation
Biotic component.Open drain valve to discharge from water purification discharge outlet.Thus, antibacterial cannot thoroughly be killed in traditional handicraft by overcoming
The problem of virus, after process, the clear water of gained can directly use.
Preferably, in above-mentioned sewage-treatment plant: helical blade is distributed with the axis body of described shaft.
By using this technical scheme: arrange helical blade and increase water-touching area, improve the stirring effect of shaft
Rate, decreases the setting quantity of shaft.
It is further preferred that in above-mentioned sewage-treatment plant: described sewage disposal box top is additionally provided with the mouth that is used as medicine.
By using this technical scheme: the medicines such as flocculant can be put into from the mouth that is used as medicine, accelerate dirty in waste water treatment box
The stirring layering efficiency of water.
It may further be preferable that above-mentioned sewage-treatment plant China: described outlet is high located at waste water treatment box side wall 1/2
At degree.
It is even furthermore preferable that in above-mentioned sewage-treatment plant: described filter material layer surface is provided with biological membranous layer, should
Heterotrophic microorganism has been entrusted one's child to the care of sb. in biological membranous layer.
By using this technical scheme: using the heterotrophic microorganism in biological membranous layer, the clogging filtrate bed of material is had
Machine thing little particle is decomposed.The cleaning that is continuously employed without for a long time realizing the filtrate bed of material is replaced, and has significantly saved people
Work cost.
Compared with prior art, this utility model structure is simply it is easy to prepare.Thoroughly kill the problem of bacterial viruses, place
After reason, the clear water of gained can directly use.The filtrate bed of material can continuously use for a long time, reduces cost of labor.

Specific embodiment
In order to be illustrated more clearly that the technical solution of the utility model, below in conjunction with accompanying drawing, this utility model is made into one
Step description.
Embodiment 1 of the present utility model as shown in Figure 1:
A kind of sewage-treatment plant, including waste water treatment box 1, settlement of sewage case 2, sewage purifier 3, the first flexible pipe 4 He
Second flexible pipe 5.
Wherein, described waste water treatment box 1 top is provided with the mouth 17 that is used as medicine.Described waste water treatment box 1 is provided with sewage inlet 11,
Treatment sewage imports in waste water treatment box 1 by described sewage inlet 11, is provided with and is driven by motor 12 in described waste water treatment box 1
Make the shaft 13 of axial-rotation, on the axis body of described shaft 13, helical blade 16 is distributed with.Described waste water treatment box 1 bottom
It is provided with sewage draining exit 14, at described waste water treatment box 1 side wall 1/2 height, be provided with the first outlet 15;Described first outlet 15 is even
Connect the first flexible pipe 4, be conducted in settlement of sewage case 2 through the first flexible pipe 4;It is provided with the filtrate bed of material 21 in described settlement of sewage case 2,
The described filtrate bed of material 21 surface is provided with biological membranous layer, has entrusted one's child to the care of sb. heterotrophic microorganism in this biological membranous layer.Described settlement of sewage case 2
Bottom is provided with the second outlet 22;Described second outlet 22 connects the second flexible pipe 5, is conducted to sewage purification through the second flexible pipe 5
In case 3;It is provided with light-transmission tube 31 in described sewage purifier 3, in described light-transmission tube 31, be provided with uviol lamp, described sewage purifier 3
Bottom is provided with water purification discharge outlet 32, and described water purification discharge outlet 32 is provided with drain valve 33.
In practice, its work process is as follows:
