Abstract
The present invention discloses a kind of chemical nickeling ageing method for treating waste liquid and used processing system, be it is a kind of can simply thoroughly it is cheap removal chemical nickeling ageing waste liquid in nickel method.The chemical nickel plating waste solution that nickel concentration is up to 5000mg/L is applied certain condition and brings it about selfdecomposition reaction by the present invention, is generated nickel and nickel oxide not soluble in water, so that chemical nickel plating waste solution nickel concentration is less than 700mg/L by physical filtering.The remaining nickel ion in waste water is completely removed by heavy metal chelating agent again, finally makes in waste water nickel content well below the discharge standard of 0.5 mg/L.To the nickel slag or nickel mud handled out since nickel content is higher, nickel recycling can be effectively recycled.
Description
Technical field
The present invention relates to a kind of wastewater treatment method, in particular to the processing method of nickel and institute in a kind of chemical nickel plating waste solution
The processing system of use.
Background technique
Chemical nickel plating is to generate N i- P amorphous deposit the effects of nickel salt and hypophosphites and effectively improve workpiece corrosion resistant
The process for treating surface of corrosion and wearability, chemical nickel phosphorus plating are not required to that external power, coating are uniform, hardness is high, wear-resisting property with it
The advantages that good, coated parts are not limited by size shape, has been widely used for every field.But chemical nickel-plating solution because
The reduction reaction property of its own leads to that plating solution is unstable, service life is short, periodically to scrap, and scraps slow in the waste liquid of generation
The influence for releasing the chemical agents such as agent, complexing agent, when handling such waste water, nickel ion is difficult to separate from waste liquid；Therefore,
Study chemical nickle-plating wastewater processing more and more attention has been paid to.
At present, the method for handling chemical nickle-plating wastewater mainly has three classes: the first kind is that heavy metal ions in wastewater passes through
The method, including chemical precipitation method, chemical reduction method and electrochemical reducing etc. that chemical reaction removes occurs.Second class is to make
The method that heavy metal in waste water is adsorbed under conditions of not changing its chemical form, is concentrated, separated, including adsorb, is molten
Agent extraction, evaporation and freezing method, ion exchange and UF membrane etc..Third class is the flocculation, absorption, product by microorganism or plant
The method that the effects of tiring out, being enriched with removes heavy metal in waste water, is repaired including bioflocculation, biochemical process and plant ecological
It is multiple etc..
In these methods, chemical precipitation method is the current processing most popular method of chemical nickle-plating wastewater, pass through to
Precipitating reagent is added in waste water, precipitates nickel ion in the form of carbonate, hydroxide, oxide or sulfide, from waste water
Middle separation, realizes purification of waste water, and the method needs a large amount of drugs, can generate a large amount of waste residues, be easy to produce secondary pollution.
It is exactly that the mechanism of chemical nickel self-catalyzed reaction is utilized that the present invention, which develops processing method, induction nickel ion mutually it
Between generate self-catalyzed reaction, thus reach by self-catalyzed reaction be converted into Autocatalytic decomposition reaction, finally make nickel ion from reaction
It is a large amount of in the process to be precipitated.This method generates that the nickel quantity of slag is few, and nickel content is high, easy to operate, conducive to the recycling for realizing nickel resources and
Cycling and reutilization is significantly.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of energy consumption is low, without secondary pollution and can completely remove chemical nickel plating
The method of nickel and used processing system in waste water.
To solve the above problems, the technical solution adopted by the present invention are as follows:
The present invention is the method for removing nickel in chemical nickeling ageing plating solution, using following steps by nickel concentration in 5000mg/L nickel plating
Aging liquid waste processing is far below the water outlet up to standard of 0.5mg/L to nickel concentration:
Step 1, the nickel plating aging waste liquid is discharged into and the substance such as sodium hydroxide, carbon that destroy reaction stability is added in reaction tank
The alkaline matters such as sour sodium make pH value reach 6 or more, then plating solution is scrapped in aging and is heated up to 80-85 degree, and energy initiation reaction is added
Ferrous material brings it about selfdecomposition reaction；
Step 2, after selfdecomposition reaction stops, the waste water in reaction tank is discharged into processing pond through plate-frame filtering, in the processing pond
10% or so heavy metal chelating agent (additional amount is 1:8 than ratio in nickel and heavy metal chelating agent quality), which is added, keeps it remaining few
It measures nickel and forms flocculent deposit precipitation;
Step 3, by processing pond treated waste water through plate-frame filtering, accurate filter filters qualified discharge or water is used reverse osmosis
It is recycled after processing thoroughly；
The present invention removes the processing system of nickel in chemical nickeling ageing plating solution, successively by reaction tank, nickel slag filtration system, processing
Pond, precipitating filtration system, reverse osmosis treatment system composition, wherein
Reaction tank handles change nickel plating aging of the nickel concentration in 5000mg/L and scraps plating solution to collect;
Pond is managed, nickel content in reaction tank has been dropped to by 5000mg/L to the change nickel plating aging of 700mg/L using heavy metal chelating agent
Plating solution flocculation sedimentation is scrapped, makes its nickel content far below 0.5mg/L discharge standard;
The waste water of above-mentioned steps processing is processed into pure water production line reuse through reverse osmosis treatment system by reverse osmosis treatment system；
The nickel ion of complex state in chemical nickel plating waste solution is first passed through chemical mode and solid nickel and nickel oxide is precipitated by the present invention, is remained
Remaining a small amount of nickel ion is again precipitated waste liquid nickel ion by using heavy metal chelating agent physics flucculation process, finally reaches water outlet
Discharge standard.The present invention can be such that heavy metal nickel in chemical nickel plating waste solution is removed with the simple method of the smallest cost, and continue
Stable reaches national emission standard, and the aging uselessization nickel-plating liquid nickel quantity of slag that the present invention is handled is few, and nickel content is high, can effectively return
Receive nickel.The present invention, which can thoroughly solve chemical nickel plating waste solution nickel, can not last up to target problem.That treated is useless for the method for the present invention
Nickel ion concentration is far below 0.5mg/L, safety and environmental protection in water, and is conducive to realize recycling and the cycling and reutilization of nickel resources.
