Description
Technical field
The present invention relates to technical field of land improvement, specifically a kind of soil conditioner and preparation method thereof.
Background technology
With the propulsion and the raising of people's living standard of increase, the urbanization of China human mortality, industrial and mineral is looked forward to
The various product demand of industry processing also increases at a high speed, and negative effect is so that industrial and mining enterprises lead in production management process
Cross the harmful heavy metal (such as Cr, Cd, Pb, As) that various approach are discharged into ambient soil to be continuously increased, heavy damage nature
Ecological environment and threaten people's health, therefore contaminated soil administers extremely urgent.
It is raw that the heavy metal of contaminated soil mainly includes mercury (Hg), cadmium (Cd), lead (Pb), chromium (Cr) and metalloid arsenic (As) etc.
The significant element of thing toxicity, and have the elements such as the zinc (Zn), copper (Cu), nickel (Ni) of certain toxicity；Essentially from agricultural chemicals, give up
Water, sludge and atmospheric sedimentation etc., such as mercury are essentially from mercury-containing waste water, and cadmium, lead contamination are essentially from smelting discharge and automobile exhaust gas
Sedimentation, arsenic is then widely used as insecticide, bactericide, rat poison and herbicide.Excessive heavy metal can cause physiological function of plants
Disorderly, trophic disturbance, element concentration coefficient in crop grain such as cadmium, mercury is higher, even more than food hygienic standard, also not shadow
Plant growth, development and yield are rung, mercury, arsenic can weaken and suppress nitrification in soil, amonifying bacteria activity in addition, influence nitrogen is supplied
Should.Heavy metal contaminants mobility very little in soil, is difficult, with water leaching, to be not microbial degradation, by food chain enter
After human body, potential hazard is very big, it should be specifically noted that preventing heavy metal to soil pollution.
At present, restoration of soil polluted by heavy metal mainly passes through two kinds of approach：One is the presence for changing heavy metal in soil
State, reduces its migration and bioavailability in the environment, and main recovery technique has agronomy and chemical method；Two be to utilize
Engineering techniques remove removing heavy metals from soil, and main recovery technique mainly has Physical, bioanalysis.
Phytoremediation is generally acknowledged ideal original position soil Treatment process, but there is obvious shortcoming：Ultraproduct is tired to plant
Often plant is short and small, biomass is relatively low, the speed of growth is slow for thing, growth cycle is long；Most of hyperaccumulative plants can only accumulate certain
Heavy metal, is not suitable for compound heavy-metal contaminated soil reparation；Phytoremediation is by soil types, temperature, humidity and nutrition etc.
Environmental condition is limited.
Chemical method is exactly to add soil conditioner to change the physics of soil, chemical property, by the adsorbing of heavy metal, is sunk
Form sediment or co-precipitation, existence of the heavy metal in soil is changed, so as to reduce its biological effectiveness and migration.
Physical engineering measure is to utilize physics (machinery), a class method of physical and chemical principle pollution administration soil, including
Heavy metal pollution of soil, elution method, heat treating process, electrolysis etc..Heavy metal pollution of soil will destroy the character of natural soils, while can also affect on to ground
Lower water security；Elution method require soil must have compared with Thief zone ability, while residual eluent can produce secondary pollution
Problem；Heat treating process remediation efficiency is relatively low and economic input is high, also there is the discharge of toxic gas and changing for soil Elemental characters
Become；Electrolysis is limited to the characteristic of soil, is not suitable for good penetrability, the soil of conductibility difference.All in all, although Physical
The heavy metal of contaminated soil can more thoroughly be removed, but exist with high costs, not be suitable for the larger soil of contaminated area,
And soil texture and soil fertility are easily destroyed, and cause secondary pollution.
Prior art such as Authorization Notice No. is CN104046361B Chinese invention patent, discloses an a kind of compound huge sum of money
Belong to contaminated soil conditioner and its application and application process, it includes following component：Plant ash, calcium magnesium phosphate, quick lime, zeolite
And organic fertilizer, the proportioning of its weight is：Plant ash:Calcium magnesium phosphate:Quick lime:Zeolite:Hydroxyapatite:Organic fertilizer=(0.3-
1.1):(0.1-1.2):(0.4-2.1):(0.1-0.6):(0.008-0.06):(0.4-1.2).It passes through quick lime, calcium and magnesium phosphorus
Heavy metal in the inorganic component fixed-contamination soil such as fertilizer, the phosphate in hydroxyapatite, potassium carbonate in plant ash, and tie
Closing the organic fertilizer such as plant ash, organic fertilizer mutually improves the fertility of contaminated soil, persistently strengthens the reparation of polluted soil.The soil
The ability that modifying agent fixes heavy metal is weaker, and soil fertility conservation degree and water retention property are undesirable.
The content of the invention
It is an object of the invention to provide a kind of energy Adsorption of Heavy Metals ion, its biological effectiveness and migration are reduced, is adjusted
