With social development, industrial resources exploitation and extensive mankind's activity, substantial amounts of mercury and arsenic is caused to be discharged into ring
In border, the surrounding mediums such as agricultural land soil, source water are polluted.Wherein, mercury is a kind of common heavy metal contaminants, with height
Poison, persistently, difficult degradation the characteristics of, mercury and mercuric compounds have very strong neurotoxicity and teratogenesis, and build-up effect and something lost
Pass toxicity substantially, mercury enters after soil, directly threaten crop safety.Arsenic be to agricultural environment and Health Impact most
Extensively, toxicity most one of maximum several pollution elements of strong, harmfulness, can trigger many diseases and arsenicalism phenomenon, right
Health has potential threat, and arsenic and arsenide are widely used in many industries, mainly passes through exploitation, processing, agriculture
The process such as medicine and chemical fertilizer application makes its residual into soil, causes soil arsenic pollution.It is outdoor by mercury, the agricultural land soil of arsenic pollution
Mercurous, the arsenic minerals slag stacked, under rainwash and surface runoff effect, heavy metal pollution of area source will be caused on a large scale,
Therefore, being badly in need of the suitable treatment technology of searching prevents the migration stain of mercury, arsenic.
Permeable reaction wall（permeable reactive barrier）Technology is to dispose active material wall in underground
Body is to intercept pollution pinnule, after making pollution pinnule by reaction medium, and its pollutant can be converted into the another of environment receiving
A kind of form, so as to realize the target for making pollutant solubility reach environmental standard.The technology is by reaction material perpendicular to underground water
It is middle pollution pinnule flow direction place, when this pinnule flows through reaction wall, with reaction material occur physics, chemistry and
Biology etc. acts on and is degraded, adsorbs, precipitates or removes, and is handled pollution pinnule, permeable reactive barrier technology early stage
It is primarily used to the reparation of polluted underground water, and is made some progress in organic matter, ammonia nitrogen and heavy metal ions, but
There is also the shortcomings of active material repairing effect is poor, construction is complicated.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art that there is provided a kind of in-situ immobilization mercury, arsenic polluted water
The permeable reaction brick of body.
The technical solution of the utility model is as follows：
The permeable reaction brick of a kind of in-situ immobilization mercury, arsenic polluted water body, it is characterised in that it is by iron carbon filler surface
Conversion zone 1 and useless slag bottom layer 2 are constituted.The permeable reaction brick of the in-situ immobilization mercury, arsenic polluted water body, it is characterised in that anti-
Answer the reaction layer of brick consistent with floor dimension.
The utility model is combined using magnetic iron ore and medical stone, with the preferable mercury removed in water body, arsenic pollution thing, and
Using waste iron slag and rubble as supporting layer, wasted resources are realized, it is simple, good purification with preparation technology
Feature, will be widely used in mercury, arsenic heavy metal-polluted water harnessing project in situ.
Described iron carbon filler reaction layer is by 10-50 parts of magnetic iron ores, 10-60 parts of medical stones, 5-15 parts of silicate cements
Mud is constituted, and described magnetic iron ore particle diameter is 1.0-5.0 millimeters, and medical stone particle diameter is 0.5-2.5 millimeters.
Described useless slag bottom layer is by 30-70 parts of iron tailings slags, 10-40 parts of rubbles and 10-20 parts of portland cement groups
Into described iron tailings slag particle footpath is 0.2-1.5 millimeters, and ballast grain sizes are 3.0-8.0 millimeters.
The permeable reaction brick is using the shaping of non-baking brick machine pressurization and vibration, and the brick is simple to manufacture, good purification, can be with
The heavy metals such as mercury, arsenic effectively in removal polluted-water.
The utility model further discloses the application method of permeable reaction brick, it is characterised in that mercury is directed to during implementation
With arsenic mine tailings stockyard, mercury and arsenic pollution farmland and water body, permeable reaction brick is assembled and is used as stockyard bank protection interior wall, farmland
Shore protection, when polluted-water oozed reaction brick wall, the huge sum of money that magnetic iron ore and medical stone in conversion zone will be removed effectively in sewage
Category, it is ensured that the heavy metal concentration in water outlet is up to standard.Monitoring result shows：The system is 80~95%, arsenic to Mercury in Water Body clearance
Clearance maintains 85-90%.
The beneficial effects of the utility model are：
The utility model is as purified in situ device, applied in the engineerings such as tailings stack, polluted agricultural land bank protection, can be effective
Mercury, arsenic in purifying water body, prevent the heavy metal pollution of area source of large area.
