Abstract

The utility model discloses an ecological restoration geofabric and belongs to the field of textile geosynthetics in an industry. The ecological restoration geofabric is formed by a three-layer structure in composite mode, the three-layer structure consists of 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 composite mode. The ecological restoration geofabric can effectively absorb heavy metals and have strong absorbability on the heavy metals and low-molecule organic compounds. The content of formed complexes is extremely low in water solution. The ecological restoration geofabric is capable of effectively purifying the heavy metals and other toxic matters from a water source on ground or air floating objects and further reducing pollution of the heavy metals on soil and water, water-saving, energy-saving, capable of releasing environmental protection and bar reinforcement water and soil loss resistance, and the like. The ecological restoration geofabric is capable of being applied to projects such as a farm field soil heavy metal treatment, a garbage landfill and a sewage processing plant. The ecological restoration geofabric has the advantages of being simple and convenient to construct, low in cost, and capable of solving the problems of strict technical requirement and high cost in existing heavy metal processing.

Description

The restoration of the ecosystem geotextile

Technical field

The utility model relates to a kind of fabrics for industrial use geosynthetics product, relates 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 the enviromental protection and improvement cost, and the social stability cost is increased, and especially sky-high price of required expense is repaired in soil pollution.Existing heavy metal treatment technology, require comparatively harsh, generally be liquid, and strict (if pH value changes to the pH value of processing 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 the processing is 1mg/L); The reason that another one is difficult to promote is that the heavy metal ion remover mostly adopts the synthetic article of chemical industry, when the heavy metal ion reaction is precipitation, has brought a large amount of organic carcinogen matter into.And " chemical leaching-chemistry is fixed-biomass modified coupling " of adopting and " chemical leaching-soil improvement " these two kinds of technology all are to mix with medicament after will pulverizing about 40 centimetres soil layer, then use water wash, the heavy metal conversion is processed in water again, although this mode is effective, processing cost is very high.

Summary of the invention

The purpose of this utility model is in order to address the above problem, a kind of restoration of the ecosystem geotextile of preventing and treating heavy metal pollution of soil to be provided.

The technical scheme that the invention for solving the technical problem adopts is: the 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 the needling process composite joint together.

The application of restoration of the ecosystem geotextile will provide new approach for the 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 that forms 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 plant to its uptake; Save water and energy, this product has ventilative, fire resistance characteristic, irrigate by traditional mode, after the water source infiltrated, the modified montmorillonite used breeze in the product was 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 the aqueous vapor exchange, make water body plant health growth on every side; The slowly-releasing environmental-protection function, present chemical fertilizer puts on after the farmland, most of along with the water leaching loss, not only reduced fertilization effect, also polluted underground water source, the active ingredient of this product---modified montmorillonite used breeze, effect with adsorption sustained-release chemical fertilizer, the water of soluble chemistry fertilizer has purified and has entered underground water through the filtration of restoration of the ecosystem geotextile, also held back fertilizer, through evidence, can save fertilizer 45%, protected simultaneously environment; 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, simultaneously, after the root system of plant passes the restoration of the ecosystem geotextile, between can produce preferably and to 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, and is aging, and good endurance is embedded in and undergroundly can bring harmful material into to soil environment, belongs to the low-carbon environment-friendly product, can provide abundant mineral matter for plant growth on the contrary.When adsorbing near after saturated, the restoration of the ecosystem geotextile can be taken out and concentrate processing from the farmland.

The beneficial effects of the utility model are: the 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 that forms 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 heavy metal to the pollution of soil and water, and save water and energy, the 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, has easy construction, the distinguishing features such as cost is low have solved existing heavy metal and have processed demanding strict technology of existing, the problem that cost is high.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
