Described rising pipe 12 place arranges gac.
Principle of work of the present utility model is as follows: ground rainwater, after storm sewer is collected, enters wet land system through the first water inlet pipe 1.First rainwater enters in rainwater cache pool 2, and rainwater cache pool 2 has the space of certain storage rainwater, and rainwater flows into clean water basin 3 through the first water distributing pore 5 again after stop after a while.Rainwater cache pool 2 not only can be used in rainwater storage, also be preliminary precipitation pond, rainwater is sufficient standing precipitation before entering clean water basin 3, prevent rainwater from carrying silt and directly enter clean water basin 3, enter the vertical current treating pond of two series connection again, cause two vertical current treating pond blockings of connecting, affect treatment effect.Meanwhile, preliminary precipitation also can remove a part of pollutent, thus reduces the processing load of two series connection vertical current treating ponds.Cache pool 2 is provided with first and draws clearly hole 14, and for drawing clearly the heavy mud in pond at set intervals, the mud drawn clearly send given place process.Be provided with a first row water pipe 10 in cache pool 2 to be communicated with municipal wastewater well, when wetland needs emptying and exclusive segment rainwater time can open water discharge valve 11, the rainwater in pond is entered waste pipe, delivers to Sewage Plant process through sewer line.
Rainwater enters clean water basin 3 through the first water distributing pore 5 after cache pool 2 stays for some time, and clean water basin 3 also have certain water holding space, can play precipitation and degraded further.Clean water basin 3 are provided with second and draw clearly hole 15, and for drawing clearly the heavy mud in pond at set intervals, the mud drawn clearly send given place process.Be provided with second water inlet pipe 16 in clean water basin 3 to be communicated with community scenery water system, when daily maybe when running into rainwater rareness, landscape water system can be introduced to keep mobility and the cyclicity of whole wetland.Be provided with a first row water pipe 10 in clean water basin 3 to be communicated with municipal wastewater well, when wetland needs emptying and exclusive segment rainwater time can open water discharge valve 11, the rainwater in pond is entered waste pipe, delivers to Sewage Plant process through sewer line.
Rainwater enters the vertical current treating pond 4 of two series connection after staying for some time through rainwater cache pool 2 and clean water basin 3 through water distributing pore 7.The vertical current treating pond of two series connection arranges filler, muskeg 18, and filler is selected applicable muskeg to grow and is beneficial to pollutent and absorbs the material removed, and is not easy blocking.Muskeg 18 selects the plant with beautification of landscape effect, and can adapt to Wetland Environment, removes various pollution substances contained in early-stage rainwater.The water side of the vertical current treating pond of two series connection is provided with rising pipe 12, rising pipe 12 is provided with outlet valve 13.
On the other hand, the flow direction of the utility model artificial swamp employing internal flow is the pattern of " up-descending ", namely described first vertical current treating pond 4 is up pond upwards, fluid flow inside direction, described second vertical current treating pond 20 is the downward downstream tank in fluid flow inside direction, and the water-in of described second vertical current treating pond 20 0.1-0.3m lower than the water outlet of the first vertical current treating pond 4, thus can ensure that rain sewage is by flowing from gravity, therefore this artificial swamp is without any need for power, only just can run voluntarily by dynamical elevation.
Adsorption layer described in the utility model is followed successively by spherical porous filler-zeolite layer, Flyash Layer from top to bottom.Spherical porous filler and zeolite mix according to a certain percentage, can increase specific surface area, improve the adsorptivity of ammonium nitrogen, and provide carrier for microorganism.In the gradually reduction of bottom due to dissolved oxygen concentration, there is a large amount of denitrifying bacteriums, promote the removal of nitrogen in rain sewage, secondly because the adsorption of Flyash Layer to phosphorus is extremely strong, effectively can remove the phosphorus in rain sewage.
When there being rainfall, the rainwater entering the vertical current treating pond of two series connection after treatment, is discharged into municipal catch-basin by rising pipe 12 and drains, or enter the reuse of community scenery water system.By the adjustment of water force and outlet valve, the flow control of rising pipe 12 in rational numerical value, to ensure that effluent quality meets the demands between flush period.When rainfall stops, wetland effluent pipe 12 also can stop draining, and the rainwater in cache pool 2, clean water basin 3 and two vertical current treating ponds 4 of connecting will be saved, for the growth water of muskeg, until next rainfall.
The size of rainwater treatment ecological wetland is determined as calculated according to service area early-stage rainwater amount and pollution level thereof.
