Description
Technical field
The present invention relates to soil remediation more particularly to a kind of crushing and screening one suitable for heavy-metal contaminated soil reparation
Machine.
Background technique
In the prior art, soil is the material base of the sustainable development of socio-economy, and protecting soil environment is to promote life
The important content of state civilization construction.
In the pollutant of serious pollution, heavy metal is primary pollution source.Due to mankind's activity, the trace meter in soil is first
The content of element in the soil is more than background value, and excess deposition causes the too high levels of heavy metal-polluted soil, causes heavy metal-polluted soil dirty
Dye.Heavy metal refers to the metal that specific gravity is equal to or more than 5.0, mainly includes the bio-toxicities such as cadmium, mercury, lead, chromium and metalloid arsenic
The elements such as significant element, and the zinc, copper, nickel that have certain toxicity.These pollution elements are mainly from pesticide, waste water, sludge
With atmospheric sedimentation etc., if cadmium, lead contamination are mainly from discharge and automobile exhaust gas sedimentation is smelted, mercury is mainly from mercury-containing waste water, arsenic
Then it is widely used as insecticide, fungicide, rat poison and herbicide.Excessive heavy metal can cause physiological function of plants disorder, battalion
Imbalance is supported, the elements such as cadmium, mercury concentration coefficient in crop grain is higher, even more than food hygienic standard, nor affects on crop
Growth, development and yield, furthermore mercury, arsenic can weaken and inhibit nitrification in soil, amonifying bacteria activity, influence Nitrogen supplying.Weight
Metal pollutant mobility very little in the soil, is not microbial degradation, after entering human body by food chain, potential hazard pole
Greatly.Stone grand style and Tailings Dam are not yet established in some mines in exploitation, and barren rock and tailing are arbitrarily stacked, and cause in tailing rich in hardly possible
The heavy metal of solution enters soil, and remaining metal waste residue with rainwater enters ground water regime after ore processing in addition, causes serious
Heavy metal pollution of soil.Industrial 10 kinds of metallic elements that have for being really divided into heavy metal: copper, lead, zinc, tin, nickel, cobalt, antimony,
Mercury, cadmium and bismuth.And for the angle of soil-plant system, international educational circles thinks, only the elements such as cadmium, cobalt, selenium to animal and
The greatest risk that human health causes damages.Human health is caused to be damaged because of food chain, mainly cadmium and selenium.
The soil remediation method of current main-stream is chemical harnessing, application No. is CN201810086251.4, entitled one kind
A kind of restorative procedure is disclosed in the elution processing method of heavy-metal contaminated soil, by being eluted soil to reach soil
It repairs, finds in actual use, if blocking meeting of soil hardening is so that elution effect reduction, furthermore soil itself before elution
Contained moisture can also make first time elution effect deviation occur and then influence the effect of subsequent soil remediation.
