The iron filings layer and middle coarse filtration layer are overlapped and are placed in above the boring aeration pipe, the middle coarse filtration
Layer is arranged close to the upper surface of surface-flow.
Further, the top water outlet is opened on a partition, which is the plate for being bordered by surface-flow and sand filter
Body, to be connected to surface-flow and sand filter.
Further, the water outlet of the sand filter is opened in the lower part far from surface-flow side plate body.
Further, the sewage treatment unit include the conditioning tank being sequentially communicated, anoxic pond, aerobic tank, sedimentation basin and in
Between pond, the intermediate pool is connected to by the lift unit with surface-flow.
Further, the lift unit includes elevator pump and water inlet pipe, lower end of the elevator pump loaded on water inlet pipe and
It is placed in the intermediate pool, and the water inlet pipe is connected to the iron catalytic oxidation component.
Compared to existing technologies, the utility model is a little as follows:
The utility model is entered by perforated pipe from surface-flow bottom using intermediate pool water pump water outlet, is discharged from top
Outflow enters sand filtration, the discharge of sand filtration standard water discharge.Boring aeration pipe is laid in surface-flow bottom simultaneously, and lower layer applies in surface-flow
If the iron filings discarded in lathe production, coarse media covering in the use of upper layer.Iron filings surface in aerobic situation with oxygen catalytic oxidation,
Tune can be passed through since the surface area of iron filings is larger by forming ferrous iron or ferric iron, the partial exfoliation that water flow keeps surface already oxidised
The calcium phosphate precipitation object of the quantity that the thickness control molysite of section aeration quantity and iron filings falls off, formation is removed by sand filtration, periodically right
Sand filtration carries out backwash, and the purpose that dosing or not dosing are lacked in dosing dephosphorization is met while removing part total phosphorus, to solve existing
There is technical problem present in technology.
Detailed description of the invention
Fig. 1 is the utility model embodiment structural schematic diagram.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.
A kind of surface flow artificial marshland comprising sewage treatment unit 1, lift unit 2, surface-flow 3 and sand filter 4.
The sewage treatment unit 1 include be sequentially communicated conditioning tank 11, anoxic pond 12, aerobic tank 13, sedimentation basin 14 and
Intermediate pool 15, the intermediate pool 15 are connected to by the lift unit 2 with surface-flow 3.Specifically: the conditioning tank
11 water inlet is sewage inlet, and anoxic pond 12 is connected to by water inlet component with anoxic pond, by sewage out of conditioning tank
