Description
Technical field
The present invention relates to a kind of special repair materials of mercury and its preparation technology.
Background technology
The pollution source of water body can be divided into endogenous and external source, will except to external source pollution during pollution administration water body
Cut off or controlled, the influence of endogenous pollution equally be can not ignore.After polluter enters water body, by precipitating, adsorbing
Approach is eventually deposited in bed mud and gradually accumulated.Because constantly enrichment accumulates, nitrogen phosphorus, oxygen consumption in polluted water body deposit
The pollutant concentrations such as organic matter, hardly degraded organic substance are often the order of magnitude multiple of each pollutant concentration in overlying water, and bed mud has
Machine material can produce the materials such as ammonia nitrogen, hydrogen sulfide, volatile organic matter under anaerobic can produce stench.So polluted-water
Bed mud be pollutant " accumulation storehouse ", can aggravate water pollution under certain condition, also can be to week with caused stench
The life of the side people has an impact.
At present according to the difference of control method principle, polluted water body deposit administering method can be divided into Physical, chemical method and
Bioanalysis.Physical control method mainly has dredging method and cladding process, and advantage is quick, but quantities is big, and cost is high, and bottom is dwelt
The ecosystem has destructiveness, and dredging method is also contemplated that bed mud placement place problem.Chemical method principle is chemical reagent and pollution
The reactions such as oxidation, reduction, precipitation, polymerization occur for thing, make pollutant that low stain or pollution-free shape are separated or be converted into from bed mud
State, but if the chemical reagent of selection is improper or dosage is inaccurate easily causes secondary pollution.Bioanalysis refers to biological utilisation bed mud
In each pollutant carry out metabolic activity so that pollutant concentration is reduced or removed, with first two method compared with cost it is low,
It is small to original ecology influence, do not produce the advantages of secondary pollution substantially, therefore be rapidly developed.
