Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with embodiment and accompanying drawing, the present invention is further illustrated, and the content that embodiment is mentioned not is limitation of the invention.
As shown in accompanying drawing 1 to Fig. 4, a kind of biological floating island, comprise with the silk screen 1 of some through holes 7 and the screen cloth 2 with some through holes 7, also comprise hollow limit pipe 3, this hollow limit pipe 3 is located in silk screen 1 around, and described screen cloth 2 is arranged at the bottom surface of silk screen 1, and the aperture of described through hole 7 is 0.8 ~ 1.2cm, in the chinampa framework that described hollow limit pipe 3 and silk screen 1 are enclosed to form, be filled with granular biology depend on carrier 5, the particle diameter that this biology depends on carrier 5 is 1.5 ~ 3cm.
Biological floating island structure of the present invention is simple, input cost is low, make water body in lake pollutent reduce and inorganization, and can water quality be improved, building and after dropping into actual motion 2 months, water quality obviously improves, water body concentration of nitrogen and phosphorus reduces more than 60% and 70% respectively, water quality is improved to III class water by the V class water of preprosthetic " water environment quality standard " (GB3838-2002) generally, and repairing effect is obvious, and practicality is stronger.
In the present embodiment, it is one or more mixtures in gac, slag, zeolite, haydite that described biology depends on carrier 5.Concrete, in the framework of described chinampa, cultivation has waterplant, and this waterplant is Herba Eichhorniae.Organic matter decomposition in water body or in underwater mud can be nutrient, the nitrite reduced in eutrophication water, the nitrogen element consumed in eutrophic water body that plant is easy to absorb by microorganism, waterplant and hydrocoles, and the excessive multiplication of algae can be suppressed, purifying water body, improve water transparency, in addition, root system of plant carries unnecessary oxygen in water, can promote that aerobic bacteria proceeds to benign state.What grow as microorganism, waterplant and hydrocoles depends on carrier, effectively can promote microorganism, the procreation of waterplant and hydrocoles and growth, therefore, plant in the present invention and microorganism synergy, mutual promotion, form benign cycle, shorten the improvement time greatly, governance efficiency is high.
It should be added that, described silk screen 1 is Stainless Steel Cloth 1, and screen cloth 2 is plastic mesh 2 or nylon screen 2, is connected between silk screen 1 and screen cloth 2 by plastic button.
See Fig. 3, in the present embodiment, the particle diameter that described biology depends on carrier 5 is 2cm, can ensure that biology depends on carrier 5 and can not come off from described screen cloth 2 or silk screen 1, can ensure that again it has larger contact surface, be convenient to depend on more microorganism, waterplant and hydrocoles etc., biological procreation growth result is better.
In the present embodiment, the area of described silk screen 1 is 2 ~ 3 square metres, namely the area of each biological floating island is 2 ~ 3 square metres, little compared with traditional chinampa cellar area, its surface-area is large, and buoyancy is large, thicker hypothallus can be carried, be similar to Lu Sheng edatope for vegetable layer provides, material density and the receptivity of plant significantly improve, and waters decontamination effect improving is also higher than traditional biological floating island.
See Fig. 4, in the present embodiment, described hollow limit pipe 3 has the water injection hole 6 for fill water, can increase or reduce the water-holding quantity in hollow limit pipe 3 by this water injection hole 6, thus hoverheight or the suspended state of biological floating island can be regulated according to actual needs, practicality is stronger.
With a wetland water body repair system for described biological floating island, the area sum of the waterplant of described biological floating island is 1% ~ 15% of Lake level change.Preferred embodiment: the area sum of the waterplant of described biological floating island is 8% of Lake level change, through actual monitoring, biological floating island of the present invention is building and after dropping into actual motion 2 months, water quality obviously improves, water body concentration of nitrogen and phosphorus reduces by 78% respectively, water quality is improved to III class water by the V class water of preprosthetic " water environment quality standard " (GB3838-2002) generally, and repairing effect is obvious, and practicality is stronger.
Preferred further, the lakeside kind being repaired lake water is implanted with Canna generalis Bailey, reed and/or cyperus alternifolius, to reduce water nutrition salt concn, reaches effect that dephosphorization is denitrogenated.
The above embodiment only have expressed one embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
