Description

A kind of river channel ecology environmental reconstruction system
Technical field
The invention belongs to river course environment renovation technique field more particularly to a kind of river channel ecology environmental reconstruction systems.
Background technique
Increase with country to ecological environment treatment dynamics, build beautiful mountains and rivers, make beautiful homeland theory go deep into The popular feeling.However as economic rapid development, a large amount of industrial wastewaters and sanitary sewage are discharged into the surface water bodies such as river and lake, this A large amount of nutritive salt are carried in a little waste water.Since being discharged into for the elements such as nitrogen, phosphorus causes algae in addition water body lacks necessary circulation And other planktonic organisms breed rapidly, the decline of Dissolved Oxygen in Water amount, water quality deterioration, fish and other biological mortality cause Water eutrophication destroys aquatic ecological balance, forms wawter bloom.And niff is issued, river is degenerated seriously, and river is slow Rush the growth for being not suitable for plant with area.
In face of increasingly sharpening for pollution of river degree, many countries, area and government take not contaminated river With the improvement of mode, administering method mainly to use clean water displacement polluted-water and taking to dredge based on desilting mode, but this Methods are all palliative a bit, replace polluted-water using clean water, the mud of lakebed can become pollution source, release again Pollutant keeps clean water contaminated；The sludge for taking the mode for dredging dredging to excavate is not that be thrown aside be exactly to be landfilled, due to Often contain germ and excessive heavy metal in sludge, the sludge Jing Guo harmless treatment is not largely thrown aside or filled, most It is used for soil as resource eventually, secondary pollution is often resulted in, has seriously affected the real achievement of comprehensive environmental improvement；Not only expend A large amount of manpower and material resources can also destroy the physical structure in river, cause the self-purification capacity of water poor, while may make pollution increasingly Seriously.With environmental consciousness, the enhancing and improvement of living standard of Ecological Concept, the requirement of impaired river course environment is transformed It is more more and more urgent.
Summary of the invention
It is an object of the invention to: it is serious for above-mentioned river channel ecology environmental damage, and clean water is used to replace contaminant water Body and taking dredges desilting mode improvement, expends a large amount of manpower and material resources, can also destroy the physical structure in river, cause water from The problem of net energy power difference, the present invention provide a kind of river channel ecology environmental reconstruction system.
The technical solution adopted by the invention is as follows:
A kind of river channel ecology environmental reconstruction system, including the sedimentation basin being arranged on river, filtering ponds and clear water river, institute Setting sediment trapping sill between sedimentation basin and filtering ponds are stated, water flowing dam, the filtering ponds are set between the filtering ponds and clear water river Including the riprap layer being laid on the surface of river bed, it is disposed with anti-seepage geotextile and element from bottom to top in the top of the riprap layer Soil layer, gravel layer, grass planting brick layer, planting soil layer and water plant layer, the clear water captation pass through water-supply-pipe and clear water river Road connection.
Preliminary sedimentation filtering of the river modernization system of the present invention first through sedimentation basin purifies river water, then through laying It is disposed with riprap layer, anti-seepage geotextile and plain soil layer, gravel layer, grass planting brick layer, plantation from bottom to top on the surface of river bed Soil layer and water plant layer, these matrix can be compacted bed mud, prevent substrate from suspending and endogenous pollution release, and mention for grass planting brick layer For basis, prevent foundation settlement, the setting of grass planting brick layer can be achieved to control flood and drain flooded fields, while also provide load for water plant Body and nutriment, geotextiles can prevent planting soil to be lost, while water body and root system of plant can penetrate geotechnique every native not water proof Cloth, the water plant planted in planting soil layer can purifying water body, build forest underwater, waterborne, make the water body scape of three-dimensional grace It sees, furthermore, riprap layer, gravel layer and grass planting brick layer form biomembrane, can provide attachment carrier for purified water type microorganism, water body can Riprap layer, gravel layer, grass planting brick layer, water plant root zone purification, thus General Promotion and maintain water body self-purification ability and Sensory effects.From the foregoing, it will be observed that the system, under the premise of ensureing river water conservancy safety, integration quickly propels river channel ecology transformation Process, control endogenous pollution of substrate sludge, restore natural type river channel ecology system at abatement pollution of area source, purify river water body, make up mesh The deficiency of the technology of preceding river regulation is single and clean-up effect is weaker etc..
As a preferred mode, the grass planting brick layer is spliced by plural block grass-planting brick, the rule of every piece of grass-planting brick Lattice are 400*400*100mm, weight >=25kg/ block, compression strength >=60kgf/cm2, porosity of=15%.
As a preferred mode, the sediment trapping sill select cemented rock, placed rockfill, steel reinforcement cage or concrete system At.
As a preferred mode, the water plant layer includes the emergent aquactic plant planted at upward slope, at main stem The submerged plant of plantation and the floating plant planted at buffer strip descending.
As a preferred mode, the emergent aquactic plant uses one of lotus, Lythrum salicaria, calamus, reed, fragrant plant Pu Or any combination, the floating plant are described heavy using one of duckweed, water lettuce, water lily and Eichhornia crassipes or any combination Water plant is using one of extra large calamus, eel grass, hornwort, watermifoil, black algae or any combination.
As a preferred mode, ominivore-fish is cultivated in the submerged plant planted at main stem and shrimps are dynamic Object.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1. modernization system construction in river of the present invention is flexibly, simply, efficiently, under the premise of ensureing river water conservancy safety, one Body quickly propels river channel ecology transformation process, and control endogenous pollution of substrate sludge, restores natural type river channel ecology at abatement pollution of area source System purifies river water body, makes up the deficiency that technology is single and clean-up effect is weaker etc. of current river regulation；
2. river modernization system of the present invention has stronger water conservancy security performance, greatly enhance the stabilization of ecology transformation Property can resist flood and wash away to the strength in riverbed and empty without being washed away or being corroded by water flow；
3. river modernization system of the present invention has stronger water purification and landscape effect, great river training is raw State effect is the important measure of more natural type River Constructions and urban ecology civilization construction；
4. river modernization system of the present invention uses remodeling method of the invention, waters bio-diversity increases, the tune in river More smoothly, the functions such as water-based recharge of groundwater, carbon fixation and oxygen release are further enhanced for water storage, flood discharge power.
