Abstract
The invention discloses a suspended-type semi-suspension artificial floating island which is composed of a stainless steel frame, planting cages, four floating balls and a fixed component, wherein the stainless steel frame (2) is a square structure with the side length of 2000mm. The planting cages are positioned in four 1000mm square spaces of the stainless steel frame, each planting cage is composed of a stainless steel mesh (5) with the pore size of 10mm and is 150mm deep, furnace slag (1) is filled in each planting cage, and submerged plants are grown on the furnace slag. An anchor hook (7) is connected with the geometric center of the stainless steel frame (2) through a fixing rope (6). Each floating ball (3) is a PVC (polyvinyl chloride) hollow ball with the diameter of 400mm, the four floating balls (3) are respectively connected with four corners of the stainless steel frame (2) through floating ball ropes (4), each floating ball rope (4) is 1200mm long, and the stainless steel frame (2) is suspended in the position 1200mm below the water surface. The suspended-type semi-suspension artificial floating island does not occupy the water surface area, and does not influence the photosynthetic reaeration efficiency of algae on the water body surface layer; the suspended-type semi-suspension artificial floating island has high purification efficiency for nitrogen and phosphorus; the suspended-type semi-suspension artificial floating island has relatively fixed position in the water body, and does not shift along with the disturbance of wind waves on the surface layer; and the suspended-type semi-suspension artificial floating island has high stability and does not incline.
Description
Technical field
Patent of the present invention belongs to water ecology recovery technique field, is specifically related to a kind of suspension type and partly suspends artificial floating island, be particularly useful for the restoration of the ecosystem of storehouse, lake nitrogen and phosphorus pollution.
Background technology
Along with the further raising of domestic industry degree, the further expanding of scale of urbanization, and a large amount of applyings of chemical fertilizer, a large amount of nitrogen phosphorus substance is directly entered or is flowed into receiving water body with rainfall runoff, considerably increase outburst probability and the outburst intensity of body eutrophication, the lake base area poor at water body flow is particularly outstanding.According to investigations, the Hu Ku of China nearly 30% is in eutrophic state, and the scope of body eutrophication is development trend.At present, body eutrophication has become one of main Environmental Problems of puzzlement China water environment safety, and therefore, the effective Treatment process seeking body eutrophication is very important.
Artificial floating island is one of nitrogen phosphorus remittance control techniques, compared with additive method, and artificial floating island technical operation low cost, not land occupation, and can good landscape effect be produced.Patent documentation " method of purifying combined-flow artificial floating island water body and device (ZL200810175300.8) " reports a kind of combined-flow artificial floating island technology effectively removing nitrogen phosphorus; Patent documentation " a kind of composite ecological floating island (ZL201120180469.X) " reports the artificial floating island technology that a kind of plant purification and microbially decontaminate combine; Patent documentation " a kind of combination unit (ZL201310277909.7) repaired for landscape water body " reports a kind of refining plant comprising the functional zone such as water quality regulation district, filtration Jie Wu district, emergent laying district, drop natural reaeration region, artificial floating island laying district.But above technology all needs to take certain water surface area, if water surface area is less, then may reduce the algae reoxygenation usefulness of water body, therefore, exploitation one does not take water surface area, and can promote that water body is clarified, it is necessary to increase the artificial floating island technology of water transparency.
Summary of the invention
The defect existed for prior art and deficiency, propose a kind of suspension type and partly to suspend artificial floating island.This device is suspended in water body, does not take water surface area, and effectively can remove the phosphorus and nitrogen in water body.
Technical scheme is as follows:
Suspension type partly suspends artificial floating island, it is characterized in that described device by stainless steel frame, plantation cage, ball float and stationary member four part form, wherein, the square structure that stainless steel frame (2) is length of side 2000mm, be welded by the stainless steel tube of diameter 20mm, and be welded with stainless steel tube strutbeam at the middle portion on stainless steel frame (2) four limit, stainless steel frame (2) is divided into the square space of 4 length of side 1000mm.Plantation cage is arranged in the square space of stainless steel frame (2) four 1000mm, is made up of, dark 150mm the stainless (steel) wire (5) of aperture 10mm, long and be widely 1000mm, Inner fills out slag (1), and depth of cracking closure 100mm plants planting submerged plant p.malaianus on slag.Stationary member is made up of static line (6) and grasp (7) two portions, and grasp (7) is connected with stainless steel frame (2) geometric centre by static line (6).Ball float (3) is diameter 400mmPVC hollow ball, has 4, is connected respectively by the corner of ball float rope (4) with stainless steel frame (2), and ball float rope (4) long 1200mm makes stainless steel frame (2) be suspended in below water surface 1200mm place.
The major advantage of this patent is as follows: (1), device are suspended in below water surface 1200mm place, do not take water surface area, does not affect the photosynthetic reoxygenation usefulness of water body top layer algae; (2), the growth of submerged plant is conducive to improving water transparency, the nitrogen phosphorus absorbed in water body, and provides attachment carrier for microorganism growth, improves the nitrogen phosphorus purification efficiency of Eco-Island further; (3), the position of this device in water body be relatively fixing, do not produce drift with the disturbance of top layer stormy waves; (4), this device stationarity is high, do not topple.
