Description
Technical field
The present invention relates to technical field of soil remediation, specifically a kind of As polluted soil repairs medicament.
Background technology
Arsenic is widely used in many industries, and its a large amount of residual to soil are made by exploitation, processing, using, the process such as discarded
In earth.According to national Soil Pollution Investigation publication, arsenic pollution point position exceeding standard rate is up to 2.7%.With urbanization, industrialize into
The quickening of journey, increasing soil is subjected to arsenic pollution;Urban strategy layout is readjusted, and substantial amounts of arsenic pollution leaves place urgency
Need to administer.Soil arsenic pollution has disguised, hysteresis quality and chronicity, it is difficult to repair.When Arsenic in Soil is accumulated to a certain extent
Afterwards, arsenic and arsenide typically can enter human body by approach such as water, air and foods, directly endanger human health.Element arsenic
Toxicity is extremely low, and arsenide is toxic, and trivalent arsenide compound is more stronger than other arsenic compound toxicity.Arsenic pollution poisoning is (anxious
Property arsenic poisoning) or inverted nuisance disease (arsenicalism) it is of common occurrence.Meanwhile, arsenic and arsenide are plant strong accumulations
Element, the growth of crops will be suppressed.
At present, the recovery technique for arsenic pollution soil mainly includes solidification and stabilization method, physical chemistry repairing method and plant
Thing repairing method., due to low cost, easy to operate and treatment effeciency is high and receives significant attention for solidification and stabilization method.But existing arsenic
Polluted Soil solidification and stabilization treatment technology technique falls behind relatively, and solidification stable pharmaceutical is expensive and pollutes environment, result in arsenic pollution
Native solidification and stabilization remediation efficiency is low, high cost, and secondary pollution and environmental risk are protruded.

As further scheme of the invention:According to mass fraction meter, it is made up of following raw material:13.5 parts of hornwort, stone
4.5 parts of cauliflower, 5.5 parts of manganese spar, 23 parts of arborvitae.
Described As polluted soil repairs the preparation method of medicament, comprises the following steps:
(1) after manganese spar first being crushed into 30-50 mesh, then through ultramicro grinding to 15-18 μm, manganese spar powder is obtained;
(2) hornwort, agar and arborvitae are dried respectively, is crushed to 120-150 mesh, obtain hornwort powder, agar
Powder and arborvitae powder;
(3) arborvitae powder is added immersion treatment 3-4h in the 7-8 times of water measured of its quality, is then 320-340W with power
Microwave treatment 3-4min, be filtrated to get arborvitae liquid and arborvitae slag, arborvitae liquid is relative density 1.10-1.12's through being concentrated under reduced pressure
Arborvitae extract solution, it is standby;
(4) arborvitae slag is placed in 540-550 DEG C of temperature lower calcination 55-65min, obtains calcining arborvitae;
(5) arborvitae extract solution is well mixed with manganese spar powder, hornwort powder, parmelia saxatilis vegetable powder, obtains mixture slurry;
(6) calcining arborvitae is placed in immersion treatment 32-35min in mixture slurry, obtains described As polluted soil and repair
Multiple medicament.
Described As polluted soil repairs application of the medicament in terms of heavy-metal contaminated soil renovation agent is prepared.
Compared with prior art, the beneficial effects of the invention are as follows:The present invention is with natural mineral, algae and timber as former
Material, by specific preparation technology be made it is a kind of can significantly reduce in soil available state arsenic (including water-soluble state, ammonium carbonate exchange
State, dissolving with hydrochloric acid state and NaOH solubilised state) content soil remediation medicament, in practical application, the soil per 1kg arsenic pollutions
Earth only needs to repair the effect that medicament can be achieved with quick significant reduction available state arsenic content with 5-10g, therefore, the present invention is repaiied
Multiple medicament has that few consumption, low cost, effect be good, free of contamination advantage.
