Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further explanation.
Referring to Fig. 1, a kind of rainwater ecological purification and stocking system, it comprises ecological purification district 3; The ecological filler 4 of filling in the ecological purification district, the neighboring area on surface, ecological purification district is an inhalant region 1, and inhalant region coarse stuff 2 is set in the inhalant region; Bottom, ecological purification district is the zone of transition 6 that filler is set, and the zone of transition bottom is ecological storage area 7, is provided with ecological storage area filler 8 in the ecological storage area; Bottom, ecological storage area is provided with layer of displacement filler 9; Layer of displacement filler inside is provided with perforated drain pipe 10, forms whole not homonymy in ecological purification district and ecological storage area and is respectively equipped with draining overflow well 11 and ventpipe 14, and said perforated drain pipe passes the layer of displacement filler and extends upward to the zone of transition top through ecological storage area; And the outlet of perforated drain pipe gets into the draining overflow well; The top of described draining overflow well is provided with overflow cover plate 15, and said ventpipe is communicated with perforated drain pipe, is provided with blow-down pipe 12 in the said perforated drain pipe the other end; Blow-down pipe penetrates the draining overflow well, and blow-down pipe is provided with blow-down pipe valve 13.
Also plant on top and be implanted with plant 5 in described ecological purification district.Described plant is a vascular plant.Described ecological filler is a gravel, and its particle diameter is 20-40mm.The edge gradient of said inhalant region is 1%-2%.Said inhalant region coarse stuff is a pebbles, and its particle diameter is 80-150mm.The filler of said zone of transition is a cobble, and its particle diameter is 60-100mm; Said ecological storage area filler is a cobble, and its particle diameter is 60-80mm.Said layer of displacement filler is a cobble, and its particle diameter is 80-100mm.Said ecological purification district and ecological storage area volume ratio are 1: 3-1: 4.
The principle of the utility model, at first, during the inhalant region of the rainwater that carries pollution of area source and air through the ecological purification district, the large-scale swimmer in the rainwater is tackled by the inhalant region coarse stuff; After getting into the ecological purification district, rainwater is with perpendicular streamed through the rainfall pattern wet land system, and the plantation plant in the ecological purification district, biologic packing material, mikrobe synergy purify rainwater; Rainwater gets into ecological storage area through the zone of transition filler on top, ecological storage area after purifying; The zone of transition filler had both played the effect of further filtration, purification rainwater; Stop the ecological filler in the ecological purification district to enter into ecological storage area simultaneously; Can also guarantee when no rain ecological storage area inner air flow, therefore also guaranteed root system of plant when no rain to ecological storage area absorption of water; Utilize ecological storage area to purify the storage and the degree of depth biopurification of back rainwater; Utilize the perforated drain pipe of drained zone to collect ecological storage area rainwater and enter wet well; Utilize high-order water shoot to guarantee the water storage capacity and help plant absorbing moisture; Utilize blow-down pipe rainwater in the emptying total system when accident and maintenance; Ecological purification district surface backwater when utilizing ventpipe exhaust and overflow heavy rain.
With conventional rainwater is example, and during rainfall, rainwater carries face of land pollutent and atmospheric falling dust flow to native system through rainwash, at first through the inhalant region coarse stuff 2 in the native system inhalant region 1, with wherein the swimmer and the suspended substance interception of comparatively large vol; After rainwater gets into ecological purification district 3, with perpendicular streamed through ecological filler 4, the fine suspension of carrying in the rainwater through physics hold back, principle such as physical and chemical adsorption removed by ecological filler 4, plant 5 root systems also have interception function to fine suspension; Ecological filler 4 epontic microbial films, the dissolved organic matter entrained to rainwater has biological degradation function; Plant 5 can provide oxygen through photosynthesis, and plant 5 also can absorb for himself growth needs nutritional substances such as nitrogen contained in the rainwater, phosphorus simultaneously.Rainwater after purifying through ecological purification district 3 through the large particle size filler in the zone of transition 6 enter into that ecological storage area 7 is further precipitated, filtration, biopurification and storage; Because rainwater residence time in ecological storage area 7 is long, filler 8 surface growth microbial films in ecological storage area carry out degree of depth degraded to contained organism in the rainwater; 7 bottoms, ecological storage area are provided with layer of displacement filler 9, and perforated drain pipe 10 places layer of displacement filler 9, can further guarantee effluent quality.Because perforated drain pipe 10 outlets are positioned at the top of zone of transition 6, can guarantee that there is water ecological storage area and is in the high-water state throughout the year, the while has guaranteed that also the plant 5 in the ecological purification district 3 also can absorb moisture and supply its growth required between rain free period.
The protection domain of the utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not break away from the scope and the spirit of the utility model the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, then the intention of the utility model also comprises these changes and is out of shape interior.
