Description
Technical field
The present invention relates to water pollution control and water resource to utilize field, and the self-purification of water is improved more particularly to one kind
The man-made lake polycrystalline substance of ability.
Background technology
The eutrophication problem of China's water body is very prominent in recent years.Lake river course is subject to extraneous contamination and imports and cause
Eutrophication, causes disruption of ecological balance, and water body blacks smelly.For man-made lake in process of construction, its polycrystalline substance only focuses on water-impervious
Effect.After the completion of this causes construction, the continuous input of external contaminant and deposition, form one layer in lakebed and easily discharge pollution
Endogenous pollution layer.With pollution accumulation, endogenous pollution release turns into lake primary pollution source, is the number of external source pollution remittance amount
Times.And lakebed endogenous pollution is administered mainly using the technology such as dredging work and sediment pollution covering.Dredging work is by endogenous pollution
When layer bed mud is excavated, it need to strictly control and excavate height, it is impossible to destroy waterproof layer, there is that operation difficulty is high, quantities is big.Bottom
Sludge-polluted soverlay technique is covered pollution layer using clay, reduces water body available capacity and quantities is big.
In disclosed patented technology, the research for being related to man-made lake polycrystalline substance is concentrated mainly on anti-seepage effect, stably
Property and promote in plant growth, and relevant publication patent is less.It is related to control the patent of water pollution temporarily to have not seen.
The content of the invention
The present invention proposes a kind of man-made lake polycrystalline substance for improving water body self-purification ability, solves extraneous contamination remittance and easily leads
The problem of causing man-made lake eutrophication, reduce the content of the pollutants such as water body nitrogen, phosphorus and heavy metal, while the battalion that bottom absorbs
Foster element is available for plant growth to absorb, and improves the self-purification capacity of water body, strengthens the impact resistance imported to extraneous contamination.
The technical proposal of the invention is realized in this way：
It is a kind of to improve the man-made lake polycrystalline substance of water body self-purification ability, including the basic unit 1, levelling laid successively from the bottom to top
Layer 2, bentone soil layer 4 and overburden layer 6, one layer of impervious barrier 3 is set between the screed-coat 2 and bentone soil layer 4, it is described
One layer of non-woven geotextile 5 is set between bentone soil layer 4 and overburden layer 6.
Preferably, the basic unit 1 is formed by artificial lake bottom rammed earth.
Preferably, the screed-coat 2 is made up of sieving fine earth, forms flat surface.
Preferably, the impervious barrier 3 is made up of polyvinyl chloride geomembrane.
Preferably, the bentone soil layer 4 is using aluminium salt, the cross-linking modified modified alta-mud mixed of molysite.
Preferably, the preparation process of modified alta-mud is：1. 10 parts by weight of bentonite and 100 parts by weight water are formulated as hanging
Turbid slurry；2. the heating alkalization of 0.1mol/L aluminum salt solutions is made as colloid；3. after colloid aging 2h, 1 parts by weight colloid and 1 weight
The suspended slurry of part is well mixed；4. aluminium cross-linked modified alta-mud is made in solution drying after mixing；5. with molysite with step 1. -4.
Same procedure, the cross-linking modified bentonite of iron is made；6. mixed with 2 parts of aluminium cross-linked modified alta-muds and 1 part of cross-linking modified bentonite of iron
Close modified alta-mud needed for being made.
Preferably, the netted water penetration geotextile material that the non-woven geotextile 5 is worked out by synthetic fibers is formed.
Preferably, the thin sand and soil of overburden layer 6 is formed.
Had the beneficial effect that caused by the present invention：The treatment after pollution pattern of man-made lake is changed into Pollution protection by the present invention
Pattern, pollutant absorbed layer is built in artificial lake bottom in advance, improve water body self-purification ability, reduce later regulation difficulty.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
It is a kind of as shown in Figure 1 to improve the man-made lake polycrystalline substance of water body self-purification ability, including lay successively from the bottom to top
Basic unit 1, screed-coat 2, bentone soil layer 4 and overburden layer 6, one layer is set between the screed-coat 2 and bentone soil layer 4 and is prevented
Infiltration layer 3, one layer of non-woven geotextile 5 is set between the bentone soil layer 4 and overburden layer 6.
Basic unit 1 is formed by artificial lake bottom rammed earth in the present embodiment, is the basis of total；Screed-coat 2 is by mistake
Sieve fine earth to form, form flat surface, prevent air and sharp object from destroying antiseepage film；Impervious barrier 3 is by polyvinyl chloride geomembrane structure
Into preventing man-made lake from seeping water.
Bentone soil layer 4 is using aluminium salt, the cross-linking modified modified alta-mud mixed of molysite, the system of modified alta-mud
It is for step：1. 10 parts by weight of bentonite and 100 parts by weight water are formulated as suspended slurry；2. 0.1mol/L aluminum salt solutions heat
Alkalization is made as colloid；3. after colloid aging 2h, 1 parts by weight colloid is well mixed with the suspended slurry of 1 parts by weight；4. after mixing
Aluminium cross-linked modified alta-mud is made in solution drying；5. with molysite with step 1. -4. same procedure, the cross-linking modified swelling of iron is made
Soil；6. it is mixed to prepare required modified alta-mud with 2 parts of aluminium cross-linked modified alta-muds and 1 part of cross-linking modified bentonite of iron.Modification is swollen
Profit soil protection waterproof blanket is not damaged by, while the pollutant ability such as modified bentonite, its Phosphate Sorption, heavy metal increases
Add.After extraneous contamination imports water body, bentone soil layer can absorb partial contamination, dense so as to reduce pollutant in water body
Degree, plays cushioning effect.And the pollutant that bentone soil layer absorbs is not easy to discharge, and reduces the endogenous dirt in man-made lake later stage
Dye amount, alleviate water body treating pressure.
The netted water penetration geotextile material that non-woven geotextile 5 is worked out by synthetic fibers is formed, main to protect lower floor's swelling
Soil prevents particle to be lost in, and control endogenous pollution does not discharge.
The thin sand and soil of overburden layer 6 is formed, and protects understructure.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
