Detailed description of the invention
The present invention relates to a kind of for the treatment of parking lot rainwater and regulate microclimate store stream wet land system, problems such as the pollution caused for parking lot rainfall runoff, rainwater resource waste, dry weather and designing.Can effective stopping at release field high temperature, effectively can reduce the pollution that parking lot rainfall runoff causes, can effectively improve parking lot environment.
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, for the treatment of parking lot rainwater and regulate microclimate store stream wet land system, the parking space in parking lot is by crossing track and intervallum intersecting partition, described intervallum is separated with careless ditch wetland 1 and underground irrigation canals and ditches by unhurried current 2 points, dividing plate, the physical features of described careless ditch wetland 1 to underground irrigation canals and ditches is elevation arrangement, described underground irrigation canals and ditches were arranged in track place, and underground irrigation canals and ditches are connected with the irrigation canals and ditches crossing lower end, track, the irrigation canals and ditches physical features crossing lower end, track is elevation arrangement, this parking lot is cross network structure, and whole system arranges trend (i.e. the direction of Fig. 1 arrows) in cross network structure with parking lot, contaminated rainwater collected by grass ditch wetland 1 comprises: rain drop erosion, the greasy dirt that parking road surface is accumulated, heavy metal, the rainfall runoff of hydrocarbon, allow rainwater catchment in preposition ecological pond 3 by the trend that arranges in parking lot.
Collect in process at current, current first flow through unhurried current dividing plate 2, flood level 19 on unhurried current dividing plate 2 plays the effect of careless ditch wetland 1 retaining of allowing, prevent careless ditch wetland 1 lack of water arid, the eyelet 20 that unhurried current dividing plate 2 is offered is when current are very fast, allows water slowly flow to lower and collects (i.e. underground irrigation canals and ditches).Wherein, bottom careless ditch wetland 1, lay antiseepage film (polyethylene waterproof composite material) 10, adopt without mud coarse sand 13 and coarse gravel 12 from top to bottom, for sewage seepage flow provides good hydraulics, there is good Nitrogen/Phosphorus Removal.Plant wetland plant 14 without on mud coarse sand 13, form the landscape effect that parking lot intervallum is good.
Be equipped with antiseepage film 10 bottom grass ditch wetland 1, careless ditch wetland 1 inner bottom fills the larger coarse gravel 12 of diameter, top fill particle diameter less without mud coarse sand 13, preliminary filtering-depositing effect is play to contaminated rainfall runoff.Certain elevation trend is set according to landform simultaneously, every certain length (10-50cm), unhurried current dividing plate 2 is set, unhurried current dividing plate 2 can arrange multi-disc in careless ditch wetland 1, it is very fast to alleviate current, allow contaminated rainfall runoff finally be collected to preposition ecological pond 3 with stable water speed simultaneously, then focus on.
Preposition ecological pond 3 has gathered the function of adjustment and water storage, and to being processed further by contaminated rainfall runoff and regulating, that can remove 60%-80% can settling particulate matter.Ecological filter bed 5 advanced treating are entered again by automatic water-distributing device 4.
Automatic water-distributing device 4 is prior art, is not described further.
Wherein, the skin of ecological filter bed 5 lays filter bed body of wall 15, and filter bed body of wall 15 is made up of the aluminium alloy plate being convenient to assemble, and is with the veneer of environment-friendly materials outside, and filter bed body of wall height 1m, its intensity meets structural requirement; The wall anti-seepage film of polyethylene waterproof composite material is laid inside filter bed body of wall 15; Ecological filter bed 5 inside are provided with ecological filler 18, ecological filler 18 comprises without mud coarse sand, cobblestone and coarse gravel, arranges from top to bottom, and the thickness formed without mud coarse sand, cobblestone and coarse gravel is at 50-100cm, for sewage seepage flow provides good hydraulics, there is good Nitrogen/Phosphorus Removal.
The drainage blanket 17 using rubble as draining is laid bottom ecological filter bed 5; The water filtered by ecological filter bed 5 enters clear water reserviors 7 by clear water from captation 6 and stores, and this system completes water storage work.Then, the clear water in clear water reserviors 7 is communicated with water return pipeline 11 or irrigation conduit by lift pump 8, provides clean water source to careless ditch wetland 1, also can reuse irrigate in green plants band 9, also can the multifunctional usage such as reuse fire-fighting, the lake water supply of periphery river.
Ecological filter bed 5 surface plantations have wetland plant, wetland plant 14 is chosen as the plant that dirt-removing power is strong and landscape effect is good, choose that handling property is good, survival rate is high, growth cycle is long, well developed root system, attractive in appearance and there is the water plant of economic worth, if reed, cattail, again power flower etc. are wetland plant, improve the ability that it is purified waste water.
This stores stream wet land system can carry out restoration of the ecosystem to contaminated rainfall runoff, remove BOD, the COD, nitrogen phosphorus compound etc. in water body, and water purification is played to the functional effect of collection, storage, reuse, be conducive to realizing water saving, water resource conservation and protection, the conservation of soil and water and waterlogging, alleviating urban sewerage and drainage system load, reduce water pollutions and improve parking lot ecological environment; The dissimilar landscape plant that wet land system adopts, and the plant cultivating of wetland periphery is the softening effect playing beautification of landscape of parking lot environment, is suitable for various types of parking lot.
System of the present invention through artificial mode to contaminated rainwater will play collection after careless ditch wetland variation, store, stores the functional effect of stream, reuse, is conducive to realizing water saving, water resource conservation and protection, the conservation of soil and water and waterlogging, alleviates urban sewerage and drainage system load, reduces water pollutions, regulates parking lot microclimate and improve ecological environment around parking lot; The dissimilar landscape plant that grass ditch wetland and surrounding thereof adopt, is the softening effect playing beautification of landscape in hard roadside, parking lot, is suitable for various types of parking lot.Compared with general park field, the careless ditch wetland of increase, has tackled rainfall runoff effectively, while achieving Rainwater Resources utilization, saves rainwater resource better, regulates parking lot weather; The plant distributions structure optimized, make filter bed remove nitrogen phosphorus compound more fully, treatment effeciency of increasing water quality, periphery plant has softened hard ground, and landscape planting effect is better; Certain demonstration effect is played to the construction of ecocity.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
