Description
Technical field
This utility model relates to heavy metal containing wastewater treatment field, particularly to a kind of nickel-containing waste water processing system.
Background technology
Nickel-containing waste water is one of waste water common in electroplating industry.Along with discharge of wastewater nickel out and compound thereof have
Toxicity, is the carcinogen generally acknowledged in the world.Nickel is possible not only in soil be enriched with, and then affects the normal growth of crops,
And also can affect fish production at water body.More seriously, nickel can form Nickel tetracarbonyl., poison with carbonyl compound in water
Property higher, if by food chain enter human body, human body will be produced harmful effect.Accordingly, as first kind pollutant, environmental protection
Nickel-containing waste water strictly must be processed regulated discharge standard at workshop floss hole and just can arrange outward by agencies dictate electroplating industry.
Along with Chinese Ministry of Environmental Protection issues GB21900-2008 " plating pollutant emission standard ", nickel-containing waste water in electroplating industry
Emission request is more strict, wherein requires that total nickel concentration may not exceed 0.5mg/L in current table 2 standard performed, and has very much
The strictest standard may be performed in some place.This proposes new requirement to the exploitation of nickel-containing waste water treatment technology and leads
To.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of high treating effect, and technique is simple, can reclaim
High added value nickel metal and the nickel-containing waste water processing system realizing waste water recycling.
For reaching above-mentioned purpose, the technical scheme that this utility model is proposed is: a kind of nickel-containing waste water processing system, including
The collection regulating reservoir that is sequentially connected by pipeline, oxidation reaction pond, sedimentation tank；The supernatant outlet of described sedimentation tank is by pipe
Road is sequentially connected with the first intermediate pool, tubular membrane segregation apparatus；The product water out of described tubular membrane segregation apparatus connects second
Intermediate pool, dense water out connects sedimentation tank by the first reflux line；The second described intermediate pool connects RO by pipeline
Film condensing device, the product water out of described RO film condensing device connects product pond, and dense water out is by the second reflux line even
Connect sedimentation tank；Described collection regulating reservoir is provided with means for feeding acid, and described oxidation reaction pond is provided with oxidant adding set,
Described sedimentation tank is provided with adder-subtractor.
Preferably, described tubular membrane segregation apparatus is provided with tube type filter membrance element, described tube type filter membrance element
In tube type filter membrance aperture be 0.05-0.2 micron.
Preferably, it is contained with liquor natrii hypochloritis in described oxidant adding set.
Use technique scheme, nickel-containing waste water processing system described in the utility model, have the beneficial effect that logical
Cross and destroy the organic complex of complex status nickel in nickel-containing waste water at acid condition by strong oxidizer so that nickel is with metal ion
State exists；Realizing the recycling of nickel hydroxide the most again under the conditions of alkalescence, waste water processes through tube type filter membrance more simultaneously,
RO reverse osmosis membrane processing, it is possible to effectively remove other impurity in waste water, it is achieved the purpose of waste water recycling.
Accompanying drawing explanation
Fig. 1 is nickel-containing waste water processing system structural representation described in the utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, this utility model is described further.
As it is shown in figure 1, nickel-containing waste water processing system described in the utility model, including the collection being sequentially connected by pipeline
Regulating reservoir 101, oxidation reaction pond 102, sedimentation tank 103；The supernatant outlet of described sedimentation tank 103 is sequentially connected with by pipeline
First intermediate pool 104, tubular membrane segregation apparatus 105；The product water out of described tubular membrane segregation apparatus 105 connects in second
Between pond 106, dense water out connects sedimentation tank 103 by the first reflux line 113；The second described intermediate pool 106 is passed through
Pipeline connects RO film condensing device 107, and the product water out of described RO film condensing device 107 connects product pond 108, dense water out
Sedimentation tank 103 is connected by the second reflux line 112；Described collection regulating reservoir 101 is provided with means for feeding acid 109, described
Oxidation reaction pond 102 is provided with oxidant adding set 110, and described sedimentation tank 103 is provided with adder-subtractor 111.
Preferably, described tubular membrane segregation apparatus 105 is provided with tube type filter membrance element, described tube type filter membrance unit
Tube type filter membrance aperture in part is 0.05-0.2 micron.
Preferably, it is contained with liquor natrii hypochloritis in described oxidant adding set 111.
Time specifically used, nickel-containing waste water is collected in collection regulating reservoir, by means for feeding acid regulation pH value to about 3, so
Rear entrance oxidation pond aoxidizes through strong oxidizer, destroys the organic complex of complex status nickel in nickel-containing waste water by strong oxidizer
Thing so that nickel exists with metal ion state；Then enter back into addition alkali regulation pH value in sedimentation tank and, to about 10, make hydroxide
Nickel produces water precipitation, reclaims nickel hydroxide precipitate, and then the supernatant in sedimentation tank carries out tubular type microfiltration successively and RO is reverse osmosis concentrated
Contracting, the product water of reverse osmosis can carry out reuse, tubular membrane microfiltration and RO reverse osmosis concentrated water and then be back to return further in sedimentation tank
Receive nickel ion.
Although specifically show and describe this utility model in conjunction with preferred embodiment, but those skilled in the art should
This is understood, in the spirit and scope of the present utility model limited without departing from appended claims, in form and details
On this utility model is made a variety of changes, be protection domain of the present utility model.
