Description
Technical field
The present invention relates to polluted water region Treatment process fields, more particularly to a kind of reparation side in heavy metal pollution waters
Method.
Background technique
In all types of industries production process, a large amount of untreated discharge of wastewater cause river water body into natural environment
The pollution of serious heavy metal.In river water body most heavy metal contaminants by precipitating, absorption with complexing, oxidation and
A variety of different physics chemical actions such as reduction, are transferred in solid phase bed mud by water body, finally deposit and be progressively enriched with, lead to bed mud
In each heavy metal species content severely exceed, cause serious environmental pollution.And heavy metal is in unstable shape in bed mud
State, migration is strong, can move towards, migrate into downstream water system with river under field conditions (factors), while ploughing as river flows into,
Forest zone etc., it is serious to destroy natural environment and the ecosystem even into the drinking water source region in downstream city, endanger the strong of the mankind
Health.
Traditional bed mud Treatment process is to plant heavy metal accumulation plant in waters, the absorption using plant to heavy metal
So that heavy metal element is fixed up with absorption, reduces the metallic element in bed mud, but that there are repairing efficiencies is long for this method, sees
Effect is slow, just the content of beary metal in bed mud can be made to be down to safe range up to the several years to ten several years.The water safety in downstream is made
At seriously threatening.
Polluted water region usually will appear the problem of water eutrophication, and plant largely overgrows, and cause oxygen content in water body anxious
The case where reducing sharply less, eventually leading to water body animal mortality, to maintain water body content, currently used means are to pass through oxygenation
Device carries out oxygenation to water body, and equipment cost is high, and energy consumption is high.
