Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
The embodiment provides a kind of Ni-containing Plating Wastewater resource utilization process, the Ni-containing Plating Wastewater money
Source is comprised the following steps using technique：
S1, Ni-containing Plating Wastewater is collected store, and remove the suspension in waste water.
Specifically, collect Ni-containing Plating Wastewater store first, then by elevator pump by nickel-containing waste water pressurized delivered to stone
Suspension in sand filter removal waste water, wherein, the control of quartz filter inlet pressure is in 0.35Mpa, pressure difference control
In 0.07Mpa, in addition, need to be backwashed to quartz filter when pressure difference is more than 0.07Mpa.Wherein, the quartz sand
The inlet pressure of filter can also be controlled in 0.3Mpa, or 0.32Mpa.
S2, partial organic substances and auxiliary agent in waste water are filtered by activated carbon.
Specifically, by partial organic substances and auxiliary agent in active carbon filter removing waste water, active carbon filter is imported and exported
Stress control need to be carried out when being more than 0.07Mpa in 0.07Mpa, pressure difference in 0.25-0.3Mpa, pressure difference control to active carbon filter
Backwash；
S3, the Ni-containing Plating Wastewater after purification is carried out successively ultrafiltration, nanofiltration and counter-infiltration operation, obtain concentrate.
Specifically, the ultrafiltration is to carry out Selective Separation to material by the microcellular structure on film surface.When liquid mixing
When thing flows through film surface under a certain pressure, small molecule solute passes through film (referred to as ultrafiltrate), and macromolecular substances are then trapped,
Macromolecular concentration gradually steps up (referred to as concentrate) in making stoste, so as to realize the mesh of the separation of large and small molecule, concentration, purification
's.
Therefore by after filtering waste water import ultrafiltration system in filter 40 minutes, and it is positive and negative it is each rinse 1 time, obtain ultrafiltration system
System permeate, wherein, the hyperfiltration membrane assembly flux in the ultrafiltration system is 60L (m3.H), and intake pressure is 0.2Mpa.
The nanofiltration is a kind of membrane separation technique between ultrafiltration and counter-infiltration, and its molecular cut off is in 80-1000
In the range of, aperture is several nanometers, and nanofiltration is obtained by concentrating and separating is carried out in ultrafiltration system permeate importing nanofiltration system
Concentrate, the operating pressure of nanofiltration system is 0.8Mpa, and the rate of recovery is 55%, and membrane flux is 16GFD；
The counter-infiltration is a kind of with pressure differential as motive force, and the UF membrane operation of solvent is isolated from solution.To film
The feed liquid of side applies pressure, and when pressure exceedes its osmotic pressure, solvent can make inverse osmosis against the direction of naturally osmotic.
So as to the solvent passed through in the low-pressure side of film, i.e. penetrating fluid；The solution that high-pressure side is concentrated, i.e. concentrate.Will be described
Nanofiltration concentrate is imported in counter-infiltration system and is further concentrated to give reverse osmosis concentrated liquid, and counter-infiltration operating pressure is
1.5Mpa, the rate of recovery is 40%, and membrane flux is 20L (m3.H).
S4, concentrate is evaporated in evaporator obtains nickel crystallization, so that the recovery to nickel is completed, the evaporation temperature
It is 160 DEG C to spend, and steam pressure is more than 0.6Mpa.
Preferably, the condensed water in the ultrafiltration system, nanofiltration system, counter-infiltration system and evaporator is in counter-infiltration system
Potcher is back to after middle desalting and purifying, the recycling of heavy metal and water is realized.
Specifically, the product processed using Ni-containing Plating Wastewater resource utilization process of the present invention and concentration are become
Change such as following table：
As seen from the above table, Ni-containing Plating Wastewater is by after Ni-containing Plating Wastewater resource utilization process of the present invention, both
Waste water can be made to reach discharge index, the nickel in waste water can also be recycled, save electroplating cost.
Ni-containing Plating Wastewater resource utilization process of the present invention removes particulate matter by by husky elimination of waste water, and by activity
Carbon is filtered off except metal in some organic pollutants and part, most makes wastewater to reach standard reuse through ultrafiltration, nanofiltration and counter-infiltration afterwards, and ooze
Recycling electroplating groove after filtrate crystallisation.
The specific embodiment of present invention described above, is not intended to limit the scope of the present invention..Any basis
Various other corresponding change and deformation that technology design of the invention is made, should be included in the guarantor of the claims in the present invention
In the range of shield.
