Abstract
The utility model discloses an ecological porous medium for the treatment of rivers and the lakes, which comprises a plurality of medium monomers made of the nitrogen and phosphorus absorption materials and a single medium monomer in sphere-shaped and quadrate-shaped surrounded from the plastic blueness and the gabion; the medium monomers are cylinder in which one or more communicated pore canals are provided. The utility model can directly be applied in the alteration of concrete slope protection, which can be fixed on the concrete slope protection through the griddings; and can plant the hydrophytes on the ecological porous medium to form an ecological slope protection to improve the purification ability of rivers and the lakes without breakage to the prior riverbank at the same time.
Description
Technical field:
The utility model relates to the ecological porous medium of a kind of application and river course, lake treatment, belongs to ecotope engineering field, particularly relates to river course, lake biological restoration and ecological recovery.
Background technology:
Along with increasing of expanding economy and population, make China's water pollution problems more and more serious without the sewage discharge of effectively handling in a large number.China's Urban Water Environment is polluted and is mainly reflected in river course, the black smelly or eutrophy of water body in lake at present, and the improvement technology adopts engineering means such as cutting dirt, revetment, desilting mostly, because the existence of urban rivers and lakes pollution of area source and endogenous pollution, the engineering means can not thoroughly solve Urban Water Environment black smelly or eutrophy problem, particularly eutrophy problem.Biological restoration and ecological recovery are the Urban Water Environment improvement methods of rising in recent years, facts have proved, biological restoration and ecological recovery are the effective ways and the necessary means of city river, lake treatment.Urban Water Environment biological restoration and ecological recovery mainly adopt technology and means such as phytoremediation, bio operon technology, artificial swamp, oxidation pond technology, artificial gravel catalytic oxidation, it is to recover the clean aerobic ecosystem of river and lake at all, improves its self-purification capacity.And river, the present most of city of China (lake) shore protection is mainly considered its flood storage, the flood discharge function of drainning off floodwaters, and adopts skeleton construction or concrete segment lining cutting, and bank protection is firm, has intercepted the ecological linkage of water and soil, causes the riverbank baldness, and waterplant can't grow; Riparian Zone does not have vesicular structure, and microfauna, fish, insect etc. can't perch procreation; Concrete revetment is under the daylight direct irradiation, and surface temperature is than real air temperature height, and particularly the slope shore protection makes both sides, river course water layer thin, and the exacerbate water temperature rise helps the algae grows breeding, takes place easily " wawter bloom "; And the concrete revetment dull coloring, structure is single, landscape effect is poor.Above reason causes that river, city (lake) species diversity is poor, self-purification capacity reduction, ecosystem fragility, in case a small amount of sewage enters, promptly may cause river Lake Water Body eutrophy even black smelly.Though someone has carried out partly improving to concrete revetment, concrete medium does not have big duct, is unfavorable for that birds and fish perch procreation; Still can not satisfy the needs of lake, river ecological recovery.Moreover, for the concrete revetment that has built up,, original bank protection all must be broken into pieces, fallen clearly if make the eco-concrete bank protection into, difficulty of construction is big, and the expense height is unfavorable for the popularization of ecological revetment renovation technique.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, and the ecological porous medium of a kind of application and river course, lake treatment is provided.
In order to achieve the above object, ecological porous medium of the present utility model comprises a plurality of by inhaling the medium monomers that the poly-phosphate material of nitrogen is made; A plurality of medium monomers are surrounded spherical or square by plastic crate or gabion; Be provided with the duct in described each medium monomer.
Owing to adopted such scheme, ecological porous medium of the present utility model can directly apply to the transformation of concrete revetment, be fixed on the available coagulation soil bank protection by grid, planting aquatic plants on it, make it to become ecological revetment, be arranged to different shapes according to river and lake natural form and view needs.The ecological revetment that porous medium is formed has the N of suction, poly-P, the short ability of giving birth to, and nutritive salt such as enrichment of N, P promotes microorganic adhesion and microfauna growth and breeding effectively, helps aquatic plants growth and purification of water quality; Space between porous medium duct and the medium also is the good place that fish, insect, birds etc. look for food, multiply simultaneously; Different water body fluidised form environment such as inner lead that porous medium causes, turbulent region etc., help increasing water body dissolved oxygen amount and hydrobiological growth, microorganism, microfauna, waterplant, interdependence between the various biologies such as higher animal, mutual restriction, common compound riparian ecosystem and the food chain formed interacts, organic pollutant and N, P nutritive salt is both by precipitation, filter, absorption, absorb, processes such as decomposition are removed, also can be by food chain by organic debris to microorganism, microfauna, higher animal-fish shift, more can absorb nutritive salt, improve lake, river natural purifying ability greatly by waterplant.

Fig. 2 is a structural representation of the present utility model.
Embodiment
As shown in Fig. 1 and Fig. 2, medium monomer 1 is a kind of by inhaling the complex ecological porous medium that the short green material sintering of the poly-P of N is made, be the garden tubular, its size is about external diameter 90mm, thickness 20mm, and height 90mm is provided with 1 or many diameters and is about duct 2 about 50mm in the body, when the duct is many, crisscross communicating between many ducts, voidage reaches 20-30%, perches for microfauna.Also be covered with soft filament (not drawing among the figure) on the cell walls, made apposition growths such as protozoon, metazoan,, further removed organic pollutant and algae in the water body for zooplankton provides the habitat.Plastic crate or gabion 3 surround sphere, not of uniform size, different combination of media such as square with medium monomer 1, be fixed on the concrete revetment of lake, existing river with grid during use, planting aquatic plants on it, (lake) bank forms the compound water purification system of compositions such as high animals such as plant, microfauna, microorganism and fish in the river.
Claims (3)
