Description
Technical field
The present invention relates to pollution processing technology field.It is more particularly related to prepared by a kind of utilization bog moss
Heavy metal absorbent and preparation method thereof.
Background technology
The big bog moss of bog moss alias, fountain moss, sphagna, sweater, distribution is most wide and common species.It is common in mountain region moistening ground
In area or marsh, more into the single phytobiocoenose of large area cushion.It is the main component source for generating peat.Due to such mass-planting
Thing have distinctive water cell, storage capacity be other mosses several times to tens times.
Heavy metal original meaning refers to the metal (density be more than 4.5 grams metals per cubic centimeter) that proportion is more than 5, including gold,
Silver, copper, iron, lead etc..Heavy metal pollution is different from the pollution of other organic compounds.Many organic compounds can pass through nature
Boundary physics itself, chemistry or biological purification, makes harmfulness reduce or release.And heavy metal has enriching, it is difficult to
Degraded in environment.
At present China due in the exploitation, smelting, process of heavy metal, cause many heavy metals for example lead, mercury, cadmium,
Cobalt etc. enters big gas and water, soil and causes serious environmental pollution.The heavy metal such as discharged with waste water, also can be even if concentration is small
Accumulate, adsorbed by fish and shellfish body surface in algae and bed mud, food chain concentration is produced, so as to cause public hazards.
In human body with protein and various enzymes strong interaction can occur for heavy metal, them is lost activity,
It may be enriched with some organs of human body, if it exceeds the limit that human body is resistant to, can cause human body acute poisoning, Asia anxious
Property poisoning, slow poisoning etc., people is known from experience and causes very big harm, for example, minamata disease (mercury pollution) and ostalgia that Japan occurs
Nuisance diseases such as sick (cadmium pollutions), is all as caused by heavy metal pollution.
