The riverbed base vegetation type ecological blanket restorative procedure
Technical field
The present invention relates to a kind of ecological river constructing technology, particularly a kind of vegetation type ecological blanket that utilizes is repaired the biological habitat of riverbed substrate, is suppressed the technology that pollutants in sediments discharges and purify river water.
Background technology
Deposit a large amount of pollution substances in river, lake and the reservoir bed mud, as the hazardous and noxious substances of nitrogen and phosphorous nutrient, difficult degradation, heavy metal etc., they can stripping reenter water body formation endogenous pollution under certain condition from bed mud, river and lake water quality is worsened, become the another big source of pollution of water body.At present, the major technique that is used to eliminate endogenous pollution has bed mud oxidation, bed mud covering, bed mud dredging etc.
The bed mud oxidation is to adopt chemical agent such as the organism of oxide deposition in bed mud such as nitrocalcite, iron(ic) chloride and lime, denitrogenation is also simultaneously with the ferrous ironic hydroxide that is converted into, thereby the oxyhydroxide of phosphorus and iron is combined closely, to reach the purpose that control endogenous phosphorus pollutes.But the chemical agent that the bed mud oxidation is adopted is easy to generate secondary pollution, may cause disadvantageous effect to lake, the river ecosystem.
It is to place one or more layers coverture on the bed mud that pollutes that bed mud covers, and polluted bed mud and water body is isolated, thereby prevent the migration of pollutants in sediments in water body.The coverture that adopts mainly contains untainted bed mud, sand, gravel or man-made land sill that some are complicated etc.Covering is as a kind of based technique for in-situ remediation of bed mud, and effect is obvious, can use simultaneously with dredging, as after dredging upper strata mud, lid layer sand can prevent the further release of the resuspending and the pollutent of lower floor's bed mud in the above.But also there are many weak points in the bed mud soverlay technique, and is big as quantities, needs a large amount of cleaning silt, covers the amount that can increase bed mud simultaneously, and water body storage capacity is diminished etc.
Bed mud dredging is to improve one of the simplest and direct method of water body environment quality, at present, the three kinds of forms such as mainly comprising mechanical dredging, hydraulic dredging process and explosion of desilting and dredging of river,lake and reservior, have dig, push away, inhale, drag, towards and six kinds of forms of construction work such as quick-fried.The bed mud dredging can be removed the endogenous pollution thing of water body fast, reduces the content of pollutent in the river water body, and water quality is improved significantly.But the bed mud dredging also can cause riverbed aquatic vegetation and microorganism habitat to disappear, and most of have the waterplant of absorption, degradation capability and bed mud top layer bacterial classification also to be walked clearly in the lump to pollutent, and the riverbed microecosystem is seriously damaged.Even water quality obviously improves after the desilting, but that also is temporary transient.Only in time repair the impaired microecosystem in riverbed after desilting, the effect of desilting is really brought into play, " resilience " phenomenon can not take place in the water quality of improvement.The riverbed microecosystem is meant algae, zooplankton, waterplant, zoobenthos that exists between effluent Lake Water Body and the riverbed interface and the minisize ecological system that microbial population constituted, and whether its existence has a significant impact the self-purification capacity tool of river Lake Water Body.At present, the reparation of riverbed microecosystem has become focus and the difficulty problem that the countries in the world environmentalist studies after the desilting.
Summary of the invention
Purpose of the present invention just is to overcome the defective separately of the Lake Water Body endogenous pollution control of above-mentioned various rivers, riverbed, bed mud dredging back microecosystem recovery technique, develop the good riverbed substrate recovery technique of a kind of comprehensive effect, make it have effective, practical, less investment, produce simple simultaneously, installation, easy construction, be not subjected to the restriction of season, time and other conditions, can suppress river lakebed mud endogenous pollution effectively, repair impaired riverbed microecosystem.
Technical scheme of the present invention is: the riverbed base vegetation type ecological blanket restorative procedure, its major technique is characterised in that with the nonwoven fabric parcel plants living matrix, make the blanket shape through trigger squeeze, shaper, coated outside one deck nylon wire, the vegetation type ecological blanket of the long 5~10m of formation, wide 1~2m, thick 5~10cm.Planting living matrix is that sandstone, the immature soil and the bed mud volume ratio by 0.2: 1: 1 is mixed, and evenly adds the waterplant seed or insert kind of a waterplant branch in planting living matrix.
Its further technical scheme is: when its technical characterictic is to use the present invention to repair the riverbed substrate, with the smooth riverbed bottom of being layed in of vegetation type ecological blanket, and all stamp the bamboo pricker at the center on four jiaos and two long limits of vegetation type ecological blanket respectively and make it be fixed in the bottom, riverbed.
The riverbed substrate prosthetic device of this vegetation type ecological blanket formula can suppress the release of pollutent in the bed mud effectively, growth along with waterplant in the vegetation type ecological blanket formula, for plant plankton, bottom-dwelling and microorganism provide the habitat, forming gradually with ecological blanket is the riverbed microecosystem of the health of core, has further strengthened the effect that control riverbed sediment pollution discharges by the system purification function of microecosystem.
Advantage of the present invention and effect are: 1. on the darker riverbed of mud, directly carry out aquatic vegetation and recover relatively difficulty, can directly be layed in the present invention on the polluted bed mud, discharge in water body by the pollutent in the effect inhibition riverbed bed mud of waterplant, overcome the problem that the dark riverbed of mud hydrophyte restoration difficulty and pollutants in sediments discharge; 2. for the riverbed that just bed mud has been carried out desilting, the biological habitat of its substrate is destroyed, pollutent in the substrate easily discharges in overlying water through the desilting disturbance and causes secondary pollution, this moment can utilize the present invention to the riverbed substrate repair, vegetation type ecological blanket is layed on the riverbed of dredging, for the riverbed biology provides the ideal habitat, repair the riverbed microecosystem fast, and the effect of passing through waterplant suppresses the secondary pollution of pollutants in sediments, the impaired and pollutants in sediments secondary release problem of the riverbed microecosystem that having overcome desilts and dredges causes; 3. the material of the present invention's use is all environmentally friendly, can not cause disadvantageous effect to lake, the river ecosystem; 4. can carry out batch production production, not be subjected to the restriction of execution conditions such as time, season, weather, place, it is very convenient, cheap that laying is installed at the scene during use, and effect is very remarkable.
