Abstract
The utility model discloses a kind of ecological blanket of in-situ immobilization polluted bed mud, the ecological blanket 1 is made up of four-layer structure, it is respectively from top to bottom top layer 11, plants generating layer 12, active layer 13 and carrier layer 14, in addition at the edge of the ecological blanket or internal with the stake 22 and the concrete nail 21 that are fixed on the ecological blanket in riverbed；The ecological blanket can be covered on contaminated Sediments, and the pollutant in isolation bed mud enters water body；Simultaneously using the active material in the water plant and active layer planted in generating layer, the pollutant in bed mud is absorbed and degraded, reach the technique effect for administering Sediments pollution.
Description
Technical field
The utility model is related to riverbed pollution processing, more particularly to a kind of in-situ immobilization pollution for being used to administer riverbed pollution
The ecological blanket of bed mud.The utility model is applied to administer the sediment pollution of the water bodys such as all kinds of seas, river, lake, reservoir, not only can be every
Pollution from bed mud to water body, can also be absorbed and be dropped to the polluter in bed mud by water plant and active material
Solution, reaches the effect of pollution control of water.
Background technology
Substantial amounts of pollutant is there are in river course, lake and Reservoir Sediment, such as nitrogen and phosphorous nutrient, heavy metal and difficult degradation have
Machine thing etc..Bed mud carries out the mass exchange of complexity with water body as the important component of water body, under certain condition, dirty
Contaminate thing can from bed mud dissolution and discharge to water body, cause water pollution.In addition, have substantial amounts of microbe survival in bed mud, its
The bottom in food chain, pollutants in sediments can jeopardize health biological in water body with the enrichment upwards step by step of food chain,
Influence water quality.Therefore, the reparation effect of bed mud and water correction play the role of close, and developing effective recovery technique becomes outstanding
To be important.
The recovery technique of sediment pollution is broadly divided into based technique for in-situ remediation and showering technology, wherein, such as Sediment Dredging
The shortcomings of there is high cost in isotonic recovery technique, quantities is big, and based technique for in-situ remediation is with its low cost, simple to operate, place
Reason area is big, enjoy favor the advantages of be not likely to produce secondary pollution.Using the peripheral doses technology in situ of cover type, it will can pollute
Bed mud is isolated with water body, effectively prevents pollutants in sediments from being migrated into water body, still, because the poor compatibility of covering, especially
There is stronger destructive power to benthon, make the application of the method by certain limitation.
The content of the invention
The problem of existing for the peripheral doses technology in situ of cover type, the utility model provide it is a kind of it is easy to operate, into
The good in-situ sediment remediation technology of this low, repairing effect.The utility model takes following technical proposals to solve above-mentioned technical problem.
The utility model provide a kind of ecological blanket of in-situ immobilization polluted bed mud, it is characterised in that the ecological blanket from
Up to include down：Top layer, the plant generating layer with water plant seed or seedling, for adsorbing water pollutant and providing aquatic plant
The active layer of thing growth substrate, the carrier layer for ensureing ecological blanket stability in water body；The edge of the ecological blanket or
Inside has the fixture being fixed on riverbed.
It is preferred that：The material on the top layer is geotextiles or polyester fiber.
It is preferred that：The plant generating layer is to wrap up water plant seed with non-woven fabric or directly insert kind of a water plant children
Seedling.
It is preferred that：The one kind or mixing of the water plant for waterweed, withered grass and in black algae are a variety of.
It is preferred that：The active layer is mixed by clay, water-loss reducer, plant grass fiber and active medium.
It is preferred that：The composition of the active medium is any in activated carbon, apatite, organic clay and aluminium modified zeolite
Plant or its any combination.
It is preferred that：The carrier layer is geomembrane or geotextiles.
It is preferred that：The fixture includes stake and concrete nail, and the stake is fixed on riverbed, and the concrete nail will be raw
State blanket is fixed in stake.
It is preferred that：The fixture includes timber, bamboo shape and peg.
The utility model has following Advantageous Effects：The ecological blanket can be covered in contaminated Sediments
On, the pollutant in isolation bed mud enters water body；Simultaneously using the active material in the water plant and active layer planted in generating layer,
Pollutant in bed mud is absorbed and degraded, the technique effect for administering Sediments pollution is reached.
Figure of description
Fig. 1 is the structural representation of the ecological blanket of in-situ immobilization polluted bed mud.
Fig. 2 is the structural representation of the ecological blanket for the in-situ immobilization polluted bed mud being laid on riverbed.
Specific implementation method
The utility model reaches the technique effect by following embodiments：
As shown in figure 1, ecological blanket 1 described in the utility model is respectively carrier layer 14 from the bottom to top, active layer 13 plants life
Layer 12 and top layer 11, are sequentially overlapped by foregoing four-layer structure and formed, and as shown in Figure 2, in the ecological blanket edge or inside
Equipped with concrete nail 21 stake 22 squeezed into riverbed is scheduled on for ecological blanket to be consolidated into 1.
The bottom is carrier layer 14：The carrier layer 14 is made up of geotextiles, geomembrane or other similar materials, is had
Certain mechanical strength, can effectively prevent that the pollutant in bed mud from entering water body, and integrally provide supporting function to ecological blanket.
It is active layer 13 in the top of the carrier layer 14：The active layer 13 by clay, water-loss reducer, plant grass fiber and
Active medium is mixed.The active medium is used to adsorbing pollutant in sludge, its composition include activated carbon, apatite,
Organic clay and aluminium modified zeolite, the composition can according to construction object specific pollution type, it is single or be used in mixed way.
In the top of the active layer 13 to plant generating layer 12, the generating layer 12 of planting is the aquatic plant wrapped up with non-woven fabric
Species, or water plant strain is directly fixed on the non-woven fabric.Water plant passes through in Root Absorption bed mud
Pollutant, and pollutant is decomposed and degraded, then by periodically gathering in or removing the water plant, reach and thoroughly go
Except the technique effect of pollutant in riverbed.
It is top layer 11 in the top of the plant generating layer 12, the material on the top layer 11 includes geotextiles and polyester fiber, used
In covering and protecting understructure, while providing living environment for benthon.
The ecological blanket 1 can be processed and lay according to the area and shape in riverbed, first by stake 21 as required
Squeeze into inside riverbed, then the ecological blanket concrete nail 22 of machine-shaping is fixed in stake 21.Can also directly it use
Timber, bamboo stake and peg are directly fixed on riverbed.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to.To this area
