Aforesaid filter well circularly purifying system, wherein the thickness of this wash-prime coat preferably is no less than 100mm; The thickness of described filter material layer preferably is no less than 700mm; The thickness of described supporting layer preferably is no less than 600mm.
Aforesaid filter well circularly purifying system, wherein the caliber of this header is preferably 300～500mm; Described a plurality of filter pipe is perpendicular to this header, and the interval of adjacent filter pipe is preferably 0.3～0.5m; The caliber of each filter pipe is preferably 50～75mm.
Aforesaid filter well circularly purifying system, wherein on this filter pipe the aperture of perforate preferably less than 9mm; Pitch of holes is preferably 0.1～0.5m.
Aforesaid filter well circularly purifying system wherein should the road setting along the river of filter well circularly purifying system, and spacing is preferably 100～300m.
The beneficial effects of the utility model are that the coarse sand in the utility model purification system filtering layer has physical adsorption and filteration, and iron ore can improve the clearance of phosphorus.Through this system handles river, the clearance of water-quality guideline total nitrogen reaches 20～55%, and the clearance of total phosphorus is reached 34～78%, the clearance of COD is 20～25%, 20～49%, and can reduce suspension content to the clearance of BOD, effluent quality is improved.In addition, this system architecture is simple, and reduced investment is pollution-free, takies soil, less riverbank, and can handle big flow river.
