Description
Technical field
The present invention relates to a kind of preposition storehouse, specially refer to a kind of landscape integrated preposition storehouse treatment system as feature of take.
Background technology
Along with rapid development of economy, the quickening of the sharp increase of population and industrialization and urbanization process, nitrogen, phosphorus nutrition material are increasing to the discharge value of water body, Lake Eutrophication aggravation, when polluted-water flow into water field of big area, administering eutrophication difficulty will further increase, therefore, at estuary of the lake, sewage disposal system is set very necessary, wherein preposition storehouse treatment system is a kind of practical technical method.
Building a dam in the Shi Ru exit of a lake, classical preposition storehouse, builds up the small reservoir that is positioned at main body lake and reservoir upstream, for holding back the pollutant that enters main body reservoir.In the research of prepositive library system in the past, be mainly to concentrate on hilly ground, utilize natural gradient, realize silt and N, P nutrients is effectively removed, due to the special geographical conditions of needs, this technology application has been subject to certain restriction.In this technology of China, obtained certain improvement in recent years, as at patent publication No. CN1621622A, disclose the area surface source pollution reinforced purification prepositive library system in ground, net river, a kind of Plain, efficiently solved surface flow pollutant, but can only control for pollution of area source; Prepositive library system (patent publication No. CN102134140A) patent that exit of a lake district natural energy source drives in addition, proposition increases natural energy source drive unit in the treatment system of preposition storehouse, lake inlet water is introduced to the diversion buffer area of regulating and storing, passing through respectively ecological intercepting and decanting zone, strengthened purification district, deep purifying district and Ecological Stabilization district, after purifying, tackle step by step by each treatment region ring ring, thereby reduce into lake pollution load.Although these technology have solved water inlet and the needed dynamical problem of strengthened purification of reservoir area, each plot structure is simple, and clean-up effect is not high, function singleness, and the purification of only take is target, lacks landscape effect.
Flood city and be positioned at Wujin of Changzhou, it is the most ancient metropolitan district that China preserves the current Western Zhou Dynasty to the The Spring and Autumn Period, approximately 1 square kilometre of area, have so far the history of 3000 nearly, this is also three Xing Zhi ancient cities, river, only three city in the world, from inner outside, Zi Cheng, sub-fosse, inner city, interior fosse, outer city, outer fosse, three city three river facies covers.Flood the ancient city with a long history more than thousand years of having experienced various vicissitudes of life, one, city, nowadays still dynamic, be now national important heritage sites protection unit and tourist attraction.With reference to history culture background, deep purifying district, preposition storehouse is designed to three city three river facies cover geometric figures, not only improved the effect that process in preposition storehouse, more increased natural landscape effect, make preposition storehouse scene winding, more beautiful things than one can take in, has realized the combination of processing and view, the unification of enhancement of environment and enjoyment attractive in appearance.
Summary of the invention
1. the technical problem that invention will solve
In processing for exit of a lake district pollutant, there is function singleness, only can control for pollution of area source, the purification of just take is target, simultaneously existing prepositive library system treatment effeciency is high and lack the problems such as view ornamental, and there is not good solution always, the invention provides a kind of landscape integrated preposition storehouse treatment system as feature of take, this system has that pollution load treatment effeciency is high, management is simple and the feature such as landscape effect.
2. technical scheme
Take a landscape integrated preposition storehouse treatment system as feature, it has comprised moisturizing pumping plant, ecological intercepting district, strengthened purification district, deep purifying district, unit, 5, Ecological Stabilization district; Moisturizing pumping plant first will enter lake water inlet and send into ecological intercepting district, enter successively again strengthened purification district, deep purifying district and Ecological Stabilization district, each district is connected successively by overfall dam, and the area of this preposition storehouse treatment system should design according to pollutant burden, and area is 15000-25000m
2.
Take a landscape integrated preposition storehouse treatment system as feature, described strengthened purification district is mutually parallel side by side with ecological intercepting district, and water inlet oppositely flows into strengthened purification district behind ecological intercepting district, and strengthened purification district is provided with folded spray field; Described Ecological Stabilization district is in downstream, deep purifying district.
The flowering marsh plants such as described folded spray field is comprised of the structure of 4 stairsteppings, and each ladder is considered as a pond (paddy field), plantation water lily.
Described deep purifying district by 3 donut earth dams that vary in size around forming; The annulus earth dam radius of outmost turns is 40-50m, middle annulus earth dam radius 25-30m, the inside annulus earth dam radius 15-20m; 3 donut earth dams interconnect perforation.
Described ecological intercepting district, area is at 4000-6000m
2, described strengthened purification district, area is at 3000-6000m
2; Described deep purifying district, area is at 5000-8000m
2; Described Ecological Stabilization district, area is at 3000-5000m
2.
3. beneficial effect
Than prior art, the invention has the beneficial effects as follows:
Each district for the treatment of system, the preposition storehouse of the present invention is connected successively by overfall dam, has drop effect, and the potential difference of upstream and downstream self-assembling formation water can strengthen aeration, increases Dissolved Oxygen in Water.
Because water inlet oppositely flows into strengthened purification district behind ecological intercepting district, when water (flow) direction changes, be more conducive to suspended particulate sedimentation.
Strengthened purification district is provided with folded spray field, folded spray field makes the stepped outflow of water, via a pond (paddy field) drop, flow to next pond (paddy field), in pond, plant the flowering marsh plants such as water lily, the beauty and the aquosity that present flower are vivaciously colourful, in flowering marsh plants purification and drop water aeration, also strengthened attractive in appearance.
Deep purifying district, is made to circulate between annulus earth dam into water around forming by 3 big or small donut earth dams of difference, has not only increased the water conservancy time of staying, improves effluent quality.
Deep purifying district is designed to three city three river facies cover geometric figures, has history culture feature and aesthetic, has realized the combination of processing and view, the unification of enhancement of environment and enjoyment attractive in appearance.
