Description

A kind of renovation agent of cation heavy-metal contaminated soil and preparation method thereof
Technical field
The present invention relates to soil remediation field, specifically a kind of renovation agent of cation heavy-metal contaminated soil.
Background technology
With the continuous development of global economy, heavy metal pollution of soil is mainly asked as what global environment quality faced The t of Hg about 1.5 ten thousand are discharged in topic, the whole world every year on average, and Ni is 1,000,000 t, and Cu is 3,400,000 t, and Pb is 5,000,000 t, and Mn is 15,000,000 t. China is accounted for the 1/5 of national total area under cultivation by the cultivated area of the heavy metal pollutions such as Cd, As, Pb, Cr, Hg.It is heavy metal-polluted Dye thing belongs to a kind of priority pollutants, and the heavy metal pollution in environment is decided by the content of heavy metal in the environment with harm The toxicity of distribution, chemical characteristic, environmental chemical behavio4, Transport And Transformation and heavy metal to biology.Mankind's activity (exploitation of mineral resources, Metal smelt, sanitary wastewater discharge, use of chemical fertilizer and agricultural chemicals etc.) Biogeochemistry that greatly accelerates heavy metal follows Ring, it is in ever-increasing trend to make the heavy metal in environment, increases harm of the heavy metal to human health.When in entrance environment Heavy metal when exceeding its capacity in the environment, you can cause the generation of heavy metal pollution.Heavy metal contaminants are persistence Pollutant, the harm to environment and human body are difficult to eliminate.Heavy metal ion is cation, has that chemical activity is strong, migration Property it is big, toxicity is lasting the features such as, in the environment be difficult degraded, its accumulation in soil, migration not only cause composition of the soil, Structure, changes of function, additionally it is possible to suppress crop root effect and photosynthesis, cause crop failure or even have no harvest, it is prior It is that heavy metal is migrated into the human body by food chain, is accumulated gradually in human body, cause the chronic heavy metal poisoning of human body, cause kidney Dirty, liver, lung, bone, reproductive organs, immune system, cardiovascular system injury, high risks are caused to health.
At present, heavy metal-polluted soil recovery technique is broadly divided into phytoremediation, microorganism remediation, physical chemistry reparation and agricultural Engineering Remediation Techniques.But the reparation floristics of phytoremediation technology is limited, and its reparation speed is slower, accumulates a large amount of weights The problems such as reprocessing of metal plant is also the principal element for limiting phytoremediation technology large-scale promotion;Microorganism remediation technology It is general only preferable to the adsorption effect of an independent heavy metal species, and because microorganism organism is smaller, the heavy metal amount of reparation It is less, therefore which also limits the application that large area field repair is carried out using microorganism;Electric repairing technique at present also in The experimental study stage, and there is also a series of limiting factor in actual applications because of the physicochemical property difference of different soils; Soil leaching technical operation is complicated, expensive;Agriculture project recovery technique needs to consume substantial amounts of manpower, financial resources, and to soil Earth disturbance is big, therefore a kind of soil-repairing agent for various heavy has wide market prospects.
