Abstract
The utility model discloses a kind of nickeliferous waste liquid electrolytic recovery device, its drip irrigation device is, comprise hold chemical nickel waste liquid water leg, electrolyzer, resin container, pickling tank, electrodeposition pond, described water leg connects electrolyzer by pipeline, described resin container comprises an entrance and two outlets, and the entrance of resin container is communicated with electrolyzer, and one of them outlet of resin container is connected with waste liquid pool, another outlet of resin container connects pickling tank, and pickling tank connects electrodeposition pond by pipeline; By adopting technique scheme, this programme mainly adopts ion exchange technique collocation electrolysis tech process nickel-containing waste water, and waste water primary treatment completes, and does not need huge neutralization precipitation pond, significantly weakens mud generation, avoids secondary pollution.
Description
Technical field
The utility model relates to a kind of nickeliferous waste liquid electrolytic recovery device.
Background technology
Electroplating industry all produces a large amount of Ni-containing Plating Wastewaters every year, and directly a kind of wasting of resources is not only in discharge, and causes severe contamination to environment.Nickel Product processing, electroplating industry all will produce a large amount of pickling nickel waste liquids every day, the acid content of this waste liquid is on the low side, nickel content is generally at about 3000ppm, traditional treatment process is: waste water produces the outer process of committee of unit, this waste liquid is added alkali neutralization by environmental protection company, produces nickel salt, discharges after tail water simple process, a large amount of sulfate species flows into environment, causes and destroys the secondary pollution of environment.Product nickel salt solid-liquid separation is more difficult, and purity is lower, and added value is low.Whole treatment process cost is high, and value of the product is low, inefficiencies and cause serious secondary pollution.
Utility model content
For the deficiency that prior art exists, the utility model provides a kind of nickeliferous waste liquid electrolytic recovery device.
For achieving the above object, the utility model provides following technical scheme: a kind of nickeliferous waste liquid electrolytic recovery device, comprise hold chemical nickel waste liquid water leg, electrolyzer, resin container, pickling tank, electrodeposition pond, described water leg connects electrolyzer by pipeline, described resin container comprises an entrance and two outlets, the entrance of resin container is communicated with electrolyzer, one of them outlet of resin container is connected with waste liquid pool, another outlet of resin container connects pickling tank, and pickling tank connects electrodeposition pond by pipeline.
By adopting technique scheme, this programme mainly adopts ion exchange technique collocation electrolysis tech process nickel-containing waste water, waste water primary treatment completes, do not need huge neutralization precipitation pond, significantly weaken mud generation, avoid secondary pollution, chemical nickel waste water in water leg electrolysis can go out metallic nickel after electrolyzer, the nickel content of chemical nickel waste water reduces gradually, in time being reduced to a certain degree, electrolysis can not go out metallic nickel, through resin container, on resin rich long-pending (ion-exchange), the concentration of nickel ion raises, continue electrolysis to go out metallic nickel through electrodeposition pond, pickling tank is used to make resin regeneration (resin in use can be saturated), waste liquid pool is used and wastewater collection.
The utility model is set to further, and described electrolyzer is ceramic diaphragm electrolyzer.
By adopting technique scheme, ceramic diaphragm cell efficiency is high, environmental protection.
The utility model is set to further, and pickling tank is sulfuric acid washing tank.
By adopting technique scheme, sulfuric acid washing efficiency is high, low price.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model electrolytic recovery device.
Reference numeral: 1, water leg; 2, electrolyzer; 3, resin container; 4, waste liquid pool; 5, pickling tank; 6, electrodeposition pond.
Embodiment
With reference to Fig. 1, the utility model electrolytic recovery device embodiment is described further.
A kind of nickeliferous waste liquid electrolytic recovery device, comprise hold chemical nickel waste liquid water leg 1, electrolyzer 2, resin container 3, pickling tank 5, electrodeposition pond 6, preferred described electrolyzer 2 is ceramic diaphragm electrolyzer 2, and ceramic diaphragm electrolyzer 2 efficiency is high, environmental protection; Preferred acid cleaning of evaporator 5 is sulfuric acid washing tank 5, and pickling efficiency is high, low price; Described water leg 1 connects electrolyzer 2 by pipeline, described resin container 3 comprises an entrance and two outlets, the entrance of resin container 3 is communicated with electrolyzer 2, one of them outlet of resin container 3 is connected with waste liquid pool 4, another outlet of resin container 3 connects pickling tank 5, and pickling tank 5 connects electrodeposition pond 6 by pipeline.
This programme mainly adopts ion exchange technique collocation electrolysis tech process nickel-containing waste water, waste water primary treatment completes, do not need huge neutralization precipitation pond, significantly weaken mud generation, avoid secondary pollution, chemical nickel waste water in water leg 1 electrolysis can go out metallic nickel after electrolyzer 2, the nickel content of chemical nickel waste water reduces gradually, in time being reduced to a certain degree, electrolysis can not go out metallic nickel, through resin container 3, on resin rich long-pending (ion-exchange), the concentration of nickel ion raises, continue electrolysis to go out metallic nickel through electrodeposition pond 6, pickling tank 5 is used to make resin regeneration (resin in use can be saturated), waste liquid pool 4 is used and wastewater collection.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
