Specific embodiment
It elaborates below in conjunction with attached drawing to specific embodiment of the present utility model:
As shown in Figure 1, being repaired for one of one preferred embodiment of the utility model to the processing of depth polluted river channel and original position
Multiple ecological mattress.The ecology mattress 1 includes chassis body 11, and the top and bottom of chassis body 11 are rectangular grid knot
Structure, and the grid opening in top grid and bottom grid corresponds, and collectively constitutes and can be used for placing the several of plantation basket 2
Rectangular reserved planting groove 12.Wherein, upper opening of the aperture of top grid as reserved planting groove 12.11 two sides of chassis body
Equipped with semicircular handle 13, convenient for mattress, zeolite, filler and the recycling of plant.Furthermore chassis body 11 is additionally provided with hinge 14, uses
Connection and fixation between adjacent body, as shown in Figure 3.The chassis body 11 is PVC material, and disposably blowing
At.PVC material is widely used, and production is simple, is suitable for extensive manufacture.
Plantation basket 2 is plastic products, plants 2 surrounding of basket and bottom uses network.It is rectangular for planting basket 2 also, and its
It is dimensioned slightly smaller than planting groove 12.When placement, plantation basket 2 is put into planting groove 12 by the aperture of top grid, plants 2 bottom of basket
Positioned at in bottom grid, and plant basket 2 it is closely coupled in the form of nested clamping with planting groove 12, that is, plant basket 2 insertion
In planting groove 12 and engaging between the two connects.
As shown in Fig. 2, plantation 2 bottom of basket is equipped with multilayer filler, lowest level is matrix 3, and middle layer is zeolite 4, upper layer
For filler 6.Matrix 3 is to be formed by alternating multilayered structure by corn sandwich layer and clay layer.The laying method of matrix 3 is to plant
The bottom of basket 2 is alternately laid with corn sandwich layer and clay layer, i.e. one layer of corn sandwich layer 31, one layer of clay layer 32, another layer corncob
Layer 31, one layer of clay layer 32, as shown in Figure 4.It should be noted that need to guarantee that the thickness of corn sandwich layer and clay layer is uniform, and thick
Degree is a little bit smaller as far as possible, generally has microorganism (especially nitrobacteria) in clay layer, corncob can conduct in use
The carrier of attached growth of microorganisms, and wherein contain a large amount of carbon, it can be very good to adjust C/N ratio, it can be as anti-
Carbon source needed for nitration reaction.Above-mentioned corn sandwich layer is made of corncob, and corncob is common agricultural wastes, is broken
It is broken into the particle that partial size is about 2cm.In addition, when necessary, microbial bacterial agent can also be increased into matrix, with quick raising nitrification
The content of microorganisms such as bacterium.
Zeolite 4 is looped around surrounding plants after being wrapped up with mesh bag, mesh bag diameter is much smaller than 4 partial size of zeolite, can after use
To be recycled by mesh bag.The utility model preferred zeolite is clinoptilolite, and clinoptilolite is environmentally friendly, recyclable to make
With time of equilibrium adsorption is short, and strong for the pollutants suction-operated such as heavy metal in river water body and nitrogen phosphorus, water quality purification function is aobvious
It writes.
Filler 6 in top layer includes cavity filling ball and 3 D elastic filler.Cavity filling ball is the modeling of diameter 2cm
Expect porous hollow sphere, uses polyolefin or polyamide-based for material, 3 D elastic filler is the axial cord body made of polyolefin
It is constituted with the strand radially to link together on rope body, this filler has corrosion-resistant, ageing-resistant, material service life length, table
Area is big, biofilm is rapid and cheap advantage.Cavity filling ball is cascaded by 3 D elastic filler, and is fixed on kind
It plants on basket 2.Cavity filling ball biofilm and can form biomembrane, biology on surface layer rapidly after submerged in the water due to large specific surface area
Also contain a large amount of microorganism in film.
Plant 5 is mainly the submerged plants such as black algae, eel grass, hornwort, and root can pass through matrix 3 and plantation 2 surrounding of basket
Mesh is taken root in bed mud, and 5 root system of plant and cauline leaf absorb and absorption abatement water body and heavy metal in bed mud, nitrogen, phosphorus and has
Machine pollutant, while photosynthesis of plant discharges O2Into in water body.
Therefore, in this ecology mattress, a large amount of microorganisms on clay layer and biomembrane, in the water body that can effectively degrade
Organic pollutant, and decompose and generate the inorganic compounds such as nitrate.These inorganic matters can be absorbed by plants again for growing,
And the oxygen that plant vital activity generates improves oxygen in water, builds aerobic nitrification environment for microorganism to promote micro- life
The growth of object forms symbiosis.
The application method of the ecology mattress are as follows:
The ecological mattress is sunken to river bed, is connected by a hinge between adjacent ecology mattress；Plant the heavy water in matrix
In growing process, root passes through matrix and plantation basket bottom and the reticular structure of surrounding is taken root in bed mud；Meanwhile it is empty
On heart filling ball rapid biofilm and surface formed biomembrane；The microorganism and the biomembrane carried in clay layer can be effective
Organic pollutant in degradation water body；The root system and cauline leaf of submerged plant absorb and the huge sum of money in water body and bed mud is cut down in absorption
Category, nitrogen, phosphorus and organic pollutant；After a period of time, ecological mattress need to be proposed from water, and replace zeolite, filler etc., and will
Absorb the submerged plant recycling of heavy metal.
Embodiment described above is a kind of preferable scheme of the utility model, and so it is not practical to limit
It is novel.Those of ordinary skill in related technical field can be in the case where not departing from the spirit and scope of the utility model
It makes a variety of changes and modification.Therefore all mode technical solutions obtained for taking equivalent substitution or equivalent transformation, all fall within
In the protection scope of the utility model.
