Description
Technical field
The present invention relates to technology of waste water control field more particularly to a kind of mixed industrial waste water administering methods.
Background technique
Since trade effluent contains a large amount of metal simple-substance and metal ion, such as mercury, chromium, cadmium and alkali, sulfide and
The inorganic matters such as salt and show unique color, pollution is very strong.If be directed into aquatic ecosystem, microorganism is not
But the concentration of heavy metal cannot be reduced, can also be enriched on the contrary, amplify its effect.After heavy metal enters organism, certain can be accumulated in
Cumulative poison, final life threatening are caused in organ.The deterioration water quality that inorganic matter has is polluted in sewage, endangers aquatile,
Harm agricultural；Some makes one slow poisoning, destroys the normal physiological processes of human body, and wherein heavy metal harm to the human body is maximum, very
It is extremely carcinogenic.For present status in China, industrial wastewater type is more, is such as directed to each waste water tailor processing scheme and builds
Sewage treatment plant, leads to that input cost is excessive and efficiency is lower.
Currently, trade effluent is administered using the processing of the means such as UF membrane, electrochemistry, bioanalysis, absorption method, absorption method technique
It is low in cost, it is without secondary pollution, but it is inefficient, it need to be handled in conjunction with other methods.Heavy metal simple substance is relative to a huge sum of money
Belong to ion to be easier to remove, but heavy metal simple substance and heavy metal ion separately remove improvement, complex steps, increased costs, if
Heavy metal ion is reduced into simple substance, operating condition is complex, higher cost, so, it can be by high-valence state heavy metal ion
It after being reduced into the heavy metal ion of lower valency, is removed together with heavy metal simple substance, for medium-sized and small enterprises, is more suitable for reality
Situation.
γ irradiation technique belongs to a kind of emerging high-level oxidation technology, and because having, applied widely, reaction speed is fast, does not produce
It the features such as raw secondary pollution, is received significant attention in environmental area.γ irradiation technique generates hydroxyl using gamma-rays and water effect
The free radicals such as free radical, hydroperoxyl radical, aqueous electron, peroxide, due to these free radicals have very high activity, be easy to
Pollutant in water, which is had an effect, causes its decomposition, to achieve the effect that water process.
Therefore the present invention studies a kind of new and effective absorption method and carries out trade effluent improvement, this method bactericidal effect is good,
It is without secondary pollution, good to the waste water control effect containing heavy metal ion.
Summary of the invention
For the problems of the prior art, the object of the present invention is to provide a kind of mixed industrial waste water administering methods, use
Be that mixed radiation technology governance sewage is uniformly administered, sterilizing and purifying after all types of industries sewage respective pretreatment, and
Remove heavy metal ion.Method of the invention is high-efficient, a variety of different types of trade effluents can be carried out mixed processing, and
Treatment effect is good, will not bring new pollutant, and after irradiation, the sewage of discharge will not generate radiation.
