Abstract
The present invention discloses a multifunctional ecological floating island. The floating island consists of several floating island units, which are fixed by the connecting plates in fastening; each floating island unit includes a hexagonal floating body frame and a provided with a plurality of planting baskets in the floating body frame; the planting basket is a regular hexagon basket with grid network on the bottom, and modified carbon fiber grass hangs below every corner of the basket; the modified carbon fiber grass is obtained by high temperature carbonization, activation, surface modification and microorganism fixing on carbon fibers; the bottom of each planting basket is covered with a filling substrate, and aquatic plants are planted on the substrate; and the plurality of planting baskets are arranged in the hexagonal floating body frame to form an integral structure. The ecological floating bed of the present invention has a stable hexagonal structure, combines floating island technology, micro-dosing technology and biological film together, and can adsorb, absorb and decompose various pollutants, beautify the urban river way or landscape water, and normally play strong power in winter.
Description
Technical field
The present invention relates to a kind of ecological floating island, specifically a kind of multifunctional ecological chinampa of pollution administration water body.
Background technology
The eutrophication of water body has become a universal phenomenon in water environment pollution in recent years.Lake, city river, landscape water are because water body flow is poor, self-purification capacity is low, and eutrophication is relatively serious.Artificial ecological floating island, as a kind of traditional water surrounding in-situ immobilization measure, has easy to use, applying flexible, is convenient to the advantages such as dismounting and thus have also been obtained and apply widely.Also because it is by plant absorption and ecological regulation and control effect, effectively pollutent in abatement water body, can build superaqual landscape and enjoy high praise always again simultaneously.But current ecological floating island can not get large-scale application because of some problems of ubiquity.One is chinampa buoyancy aid many employings bamboo pole, cystose, plastic plate, tire, stainless steel adds polystyrene foamed, special polystyrene foamed adds Special synthetic resin, the conventional material such as salinization ethylene synthase resin and light weight concrete, above-mentioned materials is work-ing life short (being less than 2-3) not only, and easily cause secondary pollution; Two is that function is relatively single, and general ecological floating island mainly plays purifying water body function by waterplant, but the area that freezes in the north, plant and buoyancy aid all cannot be survived the winter.Therefore, when building artificial ecological floating island, should make that chinampa stability is high, pollution-free, the life-span is long, making chinampa function many again, energy maladjustment environment.
Summary of the invention
For problems of the prior art, the invention provides a kind of multifunctional ecological chinampa administered for polluted-water.This chinampa adopts the pollution-free carbon-fibre composite of high strength, and have the regular hexagon chinampa structure of steadiness, function is many, strong adaptability, can adsorb, absorb each pollutant of Sum decomposition, all right river course, beautifying city or landscape water, and still can normally play its power winter.
The present invention is by the following technical solutions:
A kind of multifunctional ecological chinampa, it is characterized in that, it is fixedly formed by the mutual snapping of web plate by several chinampa unit; Described chinampa unit comprises regular hexagon buoyancy aid frame and is arranged on the some plantation baskets in buoyancy aid frame; Described plantation basket is regular hexagon basket, and bottom is grid screen, and each corner angle underhung of basket has modified carbon fiber grass; Described modified carbon fiber grass is Carbon fibe through high temperature cabonization, activation, surface modification and again through microorganism set gained; Filling substrate is coated with, planting aquatic plants in matrix at the bottom of described plantation basket; Described some plantation baskets are built in regular hexagon buoyancy aid frame and form integrative-structure.
Mid point and hexagonal edges and corners on described regular hexagon buoyancy aid frame every bar limit are also provided with connecting hole, and some chinampas unit inserts connecting hole by the joint pin of web plate and fixes fastening.
Described web plate is the sufficient web plate of bar shaped two or trilateral tripodia web plate.
Matrix in described plantation basket is straw or straw and immobilized microorganism microbial inoculum mixing gained, and mixing quality ratio is determined according to water pollution situation and season.
Described immobilized microorganism microbial inoculum is that nitrifier, denitrifying bacteria, polyP bacteria, phosphorus decomposing fungi are according to the mass ratio mixing gained of 3:2:2:1.
In described plantation basket, stromal thickness is 30-60mm.
In described plantation basket, planting plants is one or more in calamus, arrowhead, Canna generalis Bailey, Chinese celery, typha minima, pale reddish brown mullet grass, watermifoil, Spiked Loosestrife, wilson iris, and planting density is 80-100 strain/m
2.
Described regular hexagon buoyancy aid frame material is carbon fiber and thermoset ting resin composite, and frame length is 1000-3000mm, and width is 100-300mm, is highly 200-300mm.
The described plantation basket length of side is 100-400mm.
The present invention adopts carbon fiber and thermoset ting resin composite as buoyancy aid frame material, have lightweight, intensity is high, anti-aging, uvioresistant and life-span long performance.The plan shape of buoyancy aid frame and plantation basket is all in regular hexagon simultaneously, and this imitative honeycomb structure has higher steadiness.Buoyancy aid frame is that integral type is connected with plantation basket, and plantation in the key side is hung with multi beam modified carbon fiber grass.This modified carbon fiber grass is in water, because its specific surface area is large, pore size distribution reasonable, height adsorbs and the feature of high-biocompatibility, the multiple-microorganisms such as good carbon element bacterium around can affect by it, quick adsorption is on carbon fibre, and breed rapidly, for microorganism and algal grown provide good environment, promote the improvement of biofilm formation and food chain, increase aqueous bio Quantityanddiversity.By the pollutent in the metabolism degraded water body of microbial film and waterplant, thus water quality is improved, transparency increase.This chinampa not only can purifying domestic sewage, aquiculture waste water, lake, river eutrophic water and micro-polluted water, but also is applicable to the process of various organic waste water.Purification efficiency is efficiently quick, all has purification function throughout the year.Have that stability is high, light weight, physical strength are large, the life-span is long, installation and maintenance are convenient, unit dose is few and the advantage such as low price, can realize the object of cost saving and working cost, its remarkable in economical benefits, application prospect is good.
Hexagon chinampa of the present invention unit both can be used alone, and can also mutually combine.Another one or two chinampas can be spliced on hexagonal any limit, can different shape be spliced into; And during splicing, six limits and two kinds of splice plates all can arbitrarily be selected, and are very easy to site work, are also conducive to large-scale production.
The invention has the beneficial effects as follows: of the present invention biological floating bedly have firm regular hexagon structure, by floating island technique, microorganism adds technology and technology of biological membrane combines, waterplant in plantation basket both can a large amount of nitrogen phosphorus of sorption enhanced under the promotion of immobilized microorganism microbial inoculum, suppresses again the outburst of algae by release allelochemical.Plant the modified carbon fiber adsorbable a large amount of particulate matter of grass and the microorganism in portion in the key, form microbial film, decompose hazardous contaminant.This chinampa is apart from absorb polluted matter and denitrogenate efficiently outside the function of phosphorus, can also river course, beautifying city or landscape water, and still can work orderly winter, sustainablely purifies water 5 ~ 10 years.
