Description
Technical field
The utility model is related to a kind of field of waste water treatment, and in particular to the online equipment for reclaiming of Ni-containing Plating Wastewater.
Background technology
Nickel plating is widely used in all conglomeraties as a kind of conventional process for treating surface in electroplating technology, its
The product of plating is also closely related with our daily lifes.In Ni-Speed, washing is the part among technique, therefore
Ni2+In the form of an ion exist in waste water, if without handle or handle will not, have to health and ecological environment
Seriously endanger.The common processing method of nickel-containing waste water has chemical precipitation method, is evaporated in vacuo recovery, electrodialysis, counter-infiltration and ion
Exchanger resin absorption etc..Chemical precipitation method surface sees that processing cost is low, in fact not low, and simply early stage equipment investment is low,
Behaving will be high than other handling process, nickel, medicament, the water such as wasted.Even the solid waste of sedimentation must need
After-treatment.Vacuum vapor deposition method processing nickel-containing waste water energy consumption is big, electrodialysis, hyperfiltration need larger equipment investment and energy
Consume, but also there is consumptive material and change the problems such as frequent.
The system applies for a patent modularized design using ripe ion exchange technique, and its design feature is more specialized, behaviour
More simplify, run more stableization, equipment investment is less, more thorough is reclaimed to nickel in waste water, more conducively energy-conservation and environmental protection.
The content of the invention
It is of the present utility model to propose a kind of online equipment for reclaiming of Ni-containing Plating Wastewater, by unique design and reasonably
Layout, forms the circulation technology system of closed type, is had using " novel ion exchange process reclaims nickel " to Ni-containing Plating Wastewater
Effect processing and reuse.
A kind of processing of Ni-containing Plating Wastewater and equipment for reclaiming that above-mentioned technical proposal is proposed, including the lifting being sequentially connected
Pump, char filter, bag hose, nickel recovery column, catcher, and connected by alkali case, sour case, thin liquid case, dope case and air pump by pipeline
Composition, the elevator pump and char filter are connect, the elevator pump connects carbon filter, and the carbon filter connects bag hose, the bag hose
Nickel recovery column is accessed, the nickel recovery column is connected with catcher.The alkali case, sour case, thin liquid case, dope case be passed through air pump and with
Nickel recovery column is connected, and the nickel recovery column is connected into char filter, sour case, thin liquid case, dope case respectively by other pipelines.
Further, above-mentioned nickel recovery column is " 3 set two with one for formula "：Nickel recovery column A and nickel recovery column B transports for tandem
OK, with reference to nickel recovery column C, the method for operation can be selected according to water situation.
The first method of operation, as first order nickel recovery column A Cr6+When leakage reaches 0.5mg/L, then second level nickel of connecting is returned
Post B is received, until nickel recovery column B reaches Cr6+Full saturation, and drive capable regeneration into from except nickel system break, now nickel recovery column B becomes
Connect and continue to run with nickel recovery column C into the first order.
Second of method of operation, nickel recovery column A+ nickel recovery column B series operations, when nickel recovery column B contains Cr6+Water outlet reaches
During 0.5mg/L, nickel recovery column A has completed the release operation of over-saturation adsorption process and parsed, by nickel recovery column B+ nickel recovery columns C
Series operation；When nickel recovery column C contains Cr6+When water outlet reaches 0.5mg/L, nickel recovery column C connects with the nickel recovery column A after parsing, such as
This operation that goes round and begins again.
Further, the selection of the above-mentioned nickel recovery column method of operation and the closure of each system circuit and aperture are by automatically controlled
System operatio controls to adjust what valve was completed.
Further, the said equipment substitutes traditional ejector using the flowmeter of more efficient, energy-conserving and environment-protective.
Further, above-mentioned Ni-containing Plating Wastewater processing and equipment for reclaiming also include providing electric power energy and control signal
Electric-control system.
The use technique and operation principle of the equipment provided above-mentioned technical proposal are explained as follows：By nickeliferous cleaning waste water
First pass around bag filter, active carbon filter to go out organic impurities, then adsorb nickel ion by nickel recovery column, when nickel is returned
Nickel ion is reclaimed by regenerating after receiving post saturation.Nickel ion recovered liquid is divided into concentrated sulfuric acid nickel and dilute sulfuric acid nickel, and it is returned respectively
Receive concentrated sulfuric acid nickel case and in dilute sulfuric acid nickel case, concentrated sulfuric acid nickel reuse, dilute sulfuric acid nickel is used as mother liquor when regenerating next time.To place
Water after reason can be passed straight back to reuse in rinse bath, can be carried out when water outlet nickel ion content is in 0.5-1mg at regeneration
Reason.
In above-mentioned technique, the ion exchange principle of nickel recovery column is：
A) ion exchange column is (with A+Nickel ion is represented, HR represents resin)：
A++RNa→RA+Na+
B) neutralization reaction：H++OH-→H2O
Due to the nickel ion that the exchange interaction by resin is gone in water removal, so will be because of tree after equipment operation some cycles
The saturation of fat and fail, it is necessary to stop bed to resin with regenerative agent (resin H2SO4And NaOH) regenerated to recover its exchange energy
Power, regeneration technology can be expressed as with chemical equation：
A) resin regeneration：RA+H2SO4→RH+ASO4
B) ion exchange resin conversion：RH+NaOH→RNa+H2O
C) parsed when Resin A adsorption column saturation backed off after random is run, replaced running by B posts+C posts=water outlet.
Compared with prior art and technique, the utility model has the following advantages that：
(1) key equipment (ion exchange column) of nickel, system design totally three sets of nickel recovery columns, you can realize that two use one are reclaimed
The standby method of operation, reduces and takes up an area, reduces investment.
(2) co-current regeneration technique is used, with favorable regeneration effect, regenerating agent consumption be low, easy to operate, resin recovers thorough
The features such as.
(3) nickel ion concentration height, desorbed solution are reclaimed and can be used for more than 2 times recyclings, makes nickel ion concentration in recovered liquid
Reach more high state.
(4) design structure uniqueness is the full saturation system of twin columns, you can isolated operation, also can be according to waste water intermediate ion concentration string
Through transport row, it is able to ensure that effluent quality.
(5) it is a whole set of core technology reclaimed to change analyzing device structure.Traditional parsing regeneration is negative pressure self-priming
Formula, parsing medicament (acid, alkali) must be pressurizeed by water pump, but the watt level that water pump is used depends not only on the straight of pipeline
Footpath, depends on system size again.When pipe diameter is big or during big device systems, water pump be then not required to using flow and power it is enough big,
Negative pressure spontaneous imbibition phenomena could be so formed, among the parsed equipment of medicament (acid, alkali) suction will be parsed by ejector.Its
The speed of adsorpting formulation and the number of pharmaceutical quantities, depend entirely on the flow that water pump crosses water.
The technical equipment that the utility model is provided realizes the circulating and recovering of Ni-containing Plating Wastewater, and can realize waste water and nickel
Recycle, in the lifting level of resources utilization, reduce production cost, in terms of reducing the pollution to environment, produce significant effect.
