Description
Technical field
The present invention relates to wastewater treatment reagent fields, and in particular to a kind of chemical nickle-plating wastewater reagent treatment and its preparation side
Method.
Background technique
Chemical nickle-plating wastewater is more using intermittent processing, this is because water quality pollutant fluctuation of concentration is larger, and for
The considerations of to processing cost, part factory can will scrap liquid and ejected wash water mixed processing, be diluted with the ejected wash water of low concentration highly concentrated
Degree scraps liquid, then carries out chemical precipitation, while reducing many and diverse degree of wastewater treatment, but with adding discharge standard increasingly tight
Severe, the mode of this type handles the standard for not caught up with discharge.
Due to containing a large amount of complexing agents in chemical nickel electroplate liquid formulation, the nickel in waste water exists in the form of complex state, and
Nonionic state is equally easy when this results in handling it without image of Buddha electronickelling, and in other words, the precipitation method of conventional dose cannot make
Removal.
And the concentration for scrapping liquid is too high, and service life is short, water is larger, and outer cost of entrusting is difficult to bear.
The present invention provide a kind of new chemical medicament specifically for the nickel-containing waste water containing complexing agent using redox it
Mode go brokenly or waste water in complexing agent, by the way that the functional group in organic matter is oxidized away, nickel exists in the form of ionic state, just
Nickel hydroxide precipitate is generated in conjunction with nickel ion in hydroxyl.
It based on the above situation, can be effective the invention proposes a kind of chemical nickle-plating wastewater reagent treatment and preparation method thereof
Solve problem above.
Summary of the invention
The purpose of the present invention is to provide a kind of chemical nickle-plating wastewater reagent treatments and preparation method thereof.The present invention provides one
