Abstract
The invention discloses a geofabric used for ecological restoration, and belongs to the field of textile geosynthetics used for industry. The geofabric is formed by a three-layer structure in a composite mode; the three-layer structure comprises an acupuncturing chopped fiber non-woven geofabric layer of 200 grams, a modified montmorillonite mineral powder layer, and a continuous fiber acupuncturing non-woven geofabric layer from top to bottom; and the three layers are connected together by acupuncturing technology in the composite mode. The geofabric is capable of absorbing heavy metals effectively, and have strong absorbability on heavy metals and low-molecule organic compounds. The content of formed complexes is extremely low in water solution. The geofabric is capable of effectively removing heavy metals and other toxic matters in surface water sources or air floating objects, further reducing soil and water pollution caused by heavy metals, and realizing water-saving and energy-saving, sustained release and environmental protection, prevention of water and soil loss via reinforcement, and the like. The geofabric can be used in projects such as farm field soil heavy metal treatment, garbage landfills and sewage processing plants. The geofabric is characterized in convenient construction, low cost, and the like, and is capable of solving problems of existing heavy metal processing that technical requirement is strict, and cost is high.
Description
Technical field
The present invention relates to a kind of fabrics for industrial use geosynthetics product, relate to specifically a kind of restoration of the ecosystem geotextile.
Background technology
In recent years, follow the industrialized fast development of China, the earth constantly suffers the injury of various heavy metal pollutions.The contamination accident of frequent outburst is suffered heavy losses, and has not only increased enviromental protection and improvement cost, also make social stability cost increase, and required expense sky-high price is especially repaired in soil pollution.Existing heavy metal treatment technology, require comparatively harsh, generally liquid, and require strict (if pH value changes to processing the pH value of object, the precipitating heavy metal particles of possibility is dissolved again), such as the factory effluent of heavy metal processing enterprise, require concentration to reach certain degree (least concentration after processing is 1mg/L); The reason that another one is difficult to promote is that heavy metal ion remover mostly adopts the synthetic article of chemical industry, when heavy metal ion reaction is precipitation, has brought a large amount of organic carcinogen matter into.And " fix-biomass modified coupling of chemical leaching-chemistry " that adopt and " chemical leaching-soil improvement " these two kinds of technology are all to mix with medicament after the soil layer of approximately 40 centimetres will being pulverized, then use water wash, heavy metal conversion is processed in water again, although this mode is effective, processing cost is very high.
Summary of the invention
To the object of the invention is in order addressing the above problem, a kind of restoration of the ecosystem geotextile of preventing and treating heavy metal pollution of soil to be provided.
The present invention solves the technical scheme that its problem adopts: restoration of the ecosystem geotextile forms by three-decker is compound, it is characterized in that: be 200g acupuncture chopped strand non-woven geotextile layer, modified montmorillonite used breeze layer, continuous fiber acupuncture nonwoven geotechnique layer of cloth from top to bottom successively, this three-decker by needling process composite joint together.
The application of restoration of the ecosystem geotextile will provide new approach for heavy metal pollution of soil control, its advantage is: effective Adsorption of Heavy Metals, modified montmorillonite used breeze in this product has strong adsorptivity to heavy metal and low-molecular-weight organic compound, minute polarity of the complex compound forming in the aqueous solution is low, can effectively purify heavy metal and other noxious materials from surface pond or air floating thing, and then reduce the uptake of plant to it; Save water and energy, this product has ventilative, fire resistance characteristic, by traditional mode, irrigate, after water source infiltrates, the modified montmorillonite used breeze in product is met water and can be expanded, and then stops underground water freely to evaporate into ground, reach the effect of water saving, but do not affect the respiration of plant, be conducive to aqueous vapor exchange, make water body plant health growth around; Slowly-releasing environmental-protection function, present chemical fertilizer, after putting on farmland, most of along with water leaching loss, not only reduced fertilization effect, also polluted underground water source, the active ingredient of this product---modified montmorillonite used breeze, have the effect of adsorption sustained-release chemical fertilizer, the water of soluble chemistry fertilizer, through the filtration of restoration of the ecosystem geotextile, has purified and has entered underground water, also held back fertilizer, through evidence, can save fertilizer 45%, protected environment simultaneously; Conserve water and soil, resistant to lodging, this product has higher shear strength, can play the effect of reinforcement in soil, effectively prevent the loss of water and soil, meanwhile, the root system of plant is through after restoration of the ecosystem geotextile, between can produce preferably and interact, effectively prevent the lodging of blowing of plant; Security is good, and the modified montmorillonite used breeze in this product belongs to inorganic material, not aging, and good endurance is embedded in and undergroundly can bring harmful material into soil environment, belongs to low-carbon environment-friendly product, can provide abundant mineral matter for plant growth on the contrary.When absorption approach saturated after, restoration of the ecosystem geotextile can be taken out and focuses on from farmland.
The invention has the beneficial effects as follows: restoration of the ecosystem geotextile is Adsorption of Heavy Metals effectively, it has strong adsorptivity to heavy metal and low-molecular-weight organic compound, minute polarity of the complex compound forming in the aqueous solution is low, can effectively purify heavy metal and other noxious materials from surface pond or air floating thing, and then the pollution of minimizing heavy metal to soil and water, and save water and energy, slowly-releasing environmental protection, the anti-soil erosion of reinforcement etc., can be widely used in farmland soil heavy metals administers, refuse landfill, the engineerings such as sewage treatment plant, there is easy construction, the distinguishing features such as cost is low, solve existing heavy metal and processed demanding strict technology of existing, the problem that cost is high.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
