Description
Technical field
The present invention relates to field of environment protection technology for treating industrial waste water, and in particular to a kind of wastewater treatment side containing cyanide
Method.
Background technology
Handling the conventional method of industrial cyanide containing wastewater at present is：According to the size of concentration of cyanide, first with suitable
Cyanide ion is oxidized to carbon dioxide and nitrogen by potassium permanganate, adds ferrous sulfate, forms it into ferro-cyanate complex compound
And cyanide ion concentration is reduced, Cyanide in Waste Water compound concentration can reach 20~50ppm, then be discharged into purification tank for liquid waste again, through life
Qualified discharge after thing processing.
But there are following deficiency for above-mentioned traditional treatment method：(1) when using potassium permanganate oxidation, brought into certain new
Pollution by manganese, this pollution by manganese are also more intractable；(2) it is complexed to form ferro-cyanate complex compound using ferrous ion and cyanide ion,
Although the cyanide ion concentration being reduction of in waste water, do not destroy cyanide ion thoroughly, be discharged into environment and leave hidden danger；
(3) this method treatment effect is not too preferable, because after method processing, cyanide ion concentration is also the failure to directly reach country
Discharge standard, its be discharged into wastewater disposal basin carry out biochemical treatment when, due to cyanide ion excessive concentration, can also kill amount of activated
Bacterium, reduces waste water treatment efficiency.
Patent CN 106348426A disclose a kind of processing method of industrial wastewater containing cyanide, it is specifically using dense
Spend and cyanide ion is oxidized to nontoxic carbon dioxide and nitrogen for 10% aqueous sodium hypochlorite solution, its cyanogen after handling
Ion concentration can reach no more than 5ppm, meet the national standard directly discharged.But sodium hypochlorite has very strong oxidation
Property and blanching effect, to human body, there is also certain harm.
Laccase as biocatalyst, can degrading phenol material, phenol can be oxidized to quinone, laccase can also make a variety of
Toxicity that is dye decolored and removing oil industry wastewater, is with a wide range of applications.Although have been reported in the prior art by
Laccase has been used in phenolic wastewater treatment, but in the processing method of cyanide wastewater, not yet someone is attempted.It is of the invention to be also
It in the experiment of laccase treatment phenol wastewater, will have been surprisingly found that laccase also has certain technology to imitate for the waste water containing cyanide
Fruit, the cyanide ion concentration after it is handled can reach no more than 5ppm, meet the national standard directly discharged.
The content of the invention
1st, goal of the invention.
The present invention provides a kind of cyanide containing wastewater for the deficiency present in conventional process cyanide containing wastewater
The new method of processing.
2nd, the technical solution adopted in the present invention.
In order to the technical solution realizing the object of the invention and use for：A kind of wastewater treatment method containing cyanide, at this
Managing method and step is：1) pH is carried out to cyanide wastewater to adjust to 4.5~6.5；2) add and paint in the cyanide wastewater after being adjusted to pH
Enzyme, is filtered after stirring；Wherein, the laccase activity control is in more than 10U/mL.
Preferably, laccase activity of the present invention is 10U/mL~30U/mL.
It is highly preferred that stirring condition is preferably：20~35 DEG C of whipping temp, when mixing time 4~5 is small.
3rd, technique effect caused by the present invention.
1) present invention is attempted laccase for handling the waste water containing cyanide first, and processing method is simple, and due to laccase
Belong to protein, can be degraded in nature, secondary pollution will not be produced to waste water.
2) not only technological operation is easy by the present invention, but also cyanide containing wastewater processed by the invention, cyanide ion concentration
No more than 5ppm, meet the national standard directly discharged, be highly suitable for industrializing implementation.
Embodiment
The present invention is further described through with reference to embodiment.
