Description
Technical field
The invention belongs to rainwater purification field, and in particular to a kind of rainwater spiral-flow filter.
Background technology
Rainfall runoff carries substantial amounts of pollutant and is discharged into urban water system, and great pollution is caused to water environment.Runoff is dirty
The noncontinuity and the explosive difficulty for all significantly increasing contamination control of dye thing conveying.But research shows, rainfall runoff is dirty
Thing is contaminated based on SS and COD, and COD and SS has good correlation.So control SS can effectively control rainfall runoff dirty
Dye.In addition, with the raising and rapid development of economy of the level of urbanization, shortage of water resources problem is increasingly serious, rainwater conduct
It is a kind of inevitable choice that important water resource, which is used appropriately,.
The rainwater biochemistry purification facility that past is commonly used, its construction period is long, floor space is big, operational management is complicated,
Pollutant removal lags in time, causes rainwater recycle rate low.Existing physical filtering purification facility exists again easily to be blocked, dimension
Protect costly, and bulky grain pollutant can only be removed, the low problem of rainwater recycle rate.
Spiral-flow filter for industries such as oil, sewage disposals is to be combined eddy flow with filtering, have concurrently cyclone without
Moving component, it is easy to operate the advantages that, introduce filtration mechanism again.Liquid to be processed enters from spiral-flow filter top, edge
The downward eddy flow of conical filter net, is collected utilization as purification thing through the liquid of screen pack, the material containing bulky grain
Mixed liquor along filter screen slide bottom, mixed liquor as pollution waste liquid from spiral-flow filter bottom exclude.If directly will be existing
Some spiral-flow filters directly apply to rainwater treatment collection, and the pollutant effluents moisture content that it is excluded is too high, and wastewater displacement is big, should
Waste water is normally fed to sewage treatment plant and handled, and the waste water of huge discharge aggravates the load of sewage disposal.
The content of the invention
The technical problems to be solved by the invention are just to provide a kind of rainwater spiral-flow filter, and it can reduce the row of waste water
Amount, mitigates follow-up sewage treatment load.
The technical problems to be solved by the invention realize that it includes the first cylinder by such technical scheme,
First cylinder bore is equipped with the first screen pack, and water inlet pipe is arranged on the first cylinder top, the first water inlet branch is arranged with water inlet pipe
Pipe and the second water inlet pipe, the first water inlet pipe connect the first screen pack inside, in the bottom sidewall of the first cylinder be provided with to
The water purification outlet pipe of external drainage, water purification outlet pipe connect the space that the first cylinder inner wall and the first screen pack surround；First filtering
Net inner bottom surface is provided with a waste water outlet pipe of the opening immediately below the cylinder of pipeline communication first, is additionally provided with inside the first screen pack
Second cylinder, the second screen pack is housed in the inner chamber of the second cylinder, the second water inlet pipe is in the second barrel top and connection second
Inside screen pack, the bottom surface opening of the second cylinder through the passage that the first screen pack bottom surface and the first cylinder inner bottom surface are formed with it is net
Water outlet pipe connects, the hollow waste water outlet pipe connected below in bottom of the second screen pack.
It is wastewater collection area inside the screen pack of spiral-flow filter, it is impossible to which wastewater collection area is fallen into by the impurity of filter screen.
The present invention forms first order spiral-flow filter by the first cylinder and the first screen pack, then by the second cylinder and the second screen pack group
Into second level spiral-flow filter, it is, the wastewater collection area among first order spiral-flow filter sets second level eddy flow again
Filter, compared with existing individually spiral-flow filter, dmp filter area is increased, improves rainwater purification during big rainfall
Water rate is received, correspondingly, the wastewater displacement of waste water outlet pipe is reduced, that is, reduces the moisture content of pollutant effluents；Meanwhile the present invention
Second level spiral-flow filter is arranged on the wastewater collection area among first order spiral-flow filter, space is effectively utilized, does not increase
Add volume and floor space.
Therefore, the present invention has the advantage that：1st, improve rainwater purification and receive water rate；2nd, wastewater displacement is reduced；3、
Volume and floor space are constant.
