Abstract
The invention relates to a browning wastewater treatment process. With the adoption of the browning wastewater treatment process, the content of organic matters in browning wastewater can be reduced, and copper in the browning wastewater is effectively recovered. The browning wastewater treatment process comprises the following steps: S1: the browning wastewater is sent to a degradation tank, so that the COD (chemical oxygen demand) value can be reduced; S: the wastewater obtained in the step S1 is subjected to filter pressing; S3: a clear liquid obtained in the step S2 is subjected to electrolysis for copper removal, and the electrolyzed solution can be discharged into a sewage system.
Description
Technical field
The present invention relates to environmental protection and energy saving technology, particularly relate to a kind of brown oxide waste liquid treatment process.
Background technology
At present, horizontal brown technique because its brown groove processing temperature is low, be horizontal operation, and raw " pink circle " problem of Bu Yi Productivity, instead of traditional melanism processing procedure substantially; In brown groove, solution is primarily of sulfuric acid, hydrogen peroxide and brown liquid composition, and wherein brown liquid is organic additive, and object is the engaging force in order to improve resin and copper; Because producing the organism (COD superelevation, reaches 20000-30000mg/l) of high density in brown oxide waste liquid, and containing monovalence copper and cupric, be how a difficult problem for industry by brown oxide waste liquid recycling treatment always.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of brown oxide waste liquid treatment process, make it have more utility value in industry.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide one and can reduce organic content in brown oxide waste liquid, the brown oxide waste liquid treatment process of copper in efficient recovery brown oxide waste liquid.
Brown oxide waste liquid treatment process of the present invention, comprises the following steps:
S1: brown oxide waste liquid is sent into degraded groove to reduce COD value;
S2: by the press filtration of step S1 gained waste liquid;
S3: step S2 gained clear liquid is carried out electrolysis with copper removal, and the solution after electrolysis can be arranged into sink drainage.
Further, hydrogen peroxide and degradation agents is added in described degraded groove.
Further, described step S2 press filtration adopts pressure filter to carry out.
Further, in described step S3, electrolysis is carried out in a cell.
Further, receiving tank is provided with between described pressure filter and electrolyzer.
Further, described degradation agents comprises ferrous sulfate.
Further, this technique comprises the steps: the brown oxide waste liquid collected to inject the reaction of degraded groove, hydrogen peroxide and degradation agents is added in degraded groove, degradation agents adopts ferrous sulfate, waste liquid after degraded injects pressure filter and carries out press filtration, and the mud after press filtration is got rid of, and remaining clear liquid stores in receiving tank, clear liquid is injected electrolyzer electrolysis copper removal afterwards, gained solution can discharge afterwards.
By such scheme, the present invention at least has the following advantages:
Technique of the present invention is by the COD value of edman degradation Edman degraded waste liquid, then removed in waste liquid by press filtration and precipitate, last electrolysis copper removal, make brown oxide waste liquid reach the COD examination criteria of country to solution, and the copper in waste liquid is reclaimed, the double benefit reaching liquid waste disposal and turn waste into wealth.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technique means of the present invention, and can be implemented according to the content of specification sheets, be described in detail as follows below with preferred embodiment of the present invention.
Embodiment
Below in conjunction with embodiment, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
A kind of brown oxide waste liquid treatment process described in a preferred embodiment of the present invention, comprises the following steps:
S1: brown oxide waste liquid is sent into degraded groove to reduce COD value;
S2: by the press filtration of step S1 gained waste liquid;
S3: step S2 gained clear liquid is carried out electrolysis with copper removal, and the solution after electrolysis can be arranged into sink drainage.
In order to reduce the COD value in waste liquid, in degraded groove, add hydrogen peroxide and degradation agents more fast and stable; Like this, hydrogen peroxide and degradation agents can remove organism in waste liquid by fast and stable, reach the examination criteria of country for COD; It should be noted that, other method can also be adopted to reduce the COD value of waste liquid, such as By Ozone, ozone adds UV method etc., but effect is all stablized not as hydrogen peroxide adds degradation agents.
In order to remove the precipitation in waste liquid as early as possible, step S2 press filtration adopts pressure filter to carry out; Like this, the precipitation in waste liquid can be removed fast by pressure filter, avoids the impact on follow-up electrolytic process.
In order to improve electrolytic efficiency, in step S3, electrolysis is carried out in a cell, is added with emulsifying agent in described electrolyzer; Like this, emulsifying agent can make cupric ion dispersity in solution better, and electrolytic efficiency promotes obviously.
Receiving tank is provided with between pressure filter and electrolyzer; Like this, receiving tank can be collected and store waste liquid, facilitates follow-up injection electrolyzer.
Degradation agents comprises ferrous sulfate; It should be noted that, degradation agents can adopt ferrous sulfate but be not limited to ferrous sulfate, can also adopt potassium bichromate etc., and every reagent that can reduce COD value in waste liquid all drops in protection scope of the present invention.
In order to isolate the copper in waste liquid, clear liquid after press filtration is injected electrolyzer electrolysis; In the present invention during electrolysis copper removal, electrolytic reaction is as follows:
Anodic reaction: H
2o → H
++ OH-
4OH-→O
2↑+2H
2O
Cathodic reaction: Cu
2++ 2e → Cu
H
2O→H
++OH-
2H
++2e→H
2↑
The nascent oxygen [O] that electrolytic process Anodic produces, the organic substance in waste liquid is oxidized further in liquid loop process, make it to be converted into carbonic acid gas and water, after institute completes down to electrolysis, cupric ion generally can be down to below 500ppm (being as the criterion with water sample actual measurement).
Embodiment 1
Brown oxide waste liquid is collected into preserving jar, then inject degraded groove and react 2 hours, hydrogen peroxide and degradation agents is added in degraded groove, degradation agents adopts ferrous sulfate, and the waste liquid after degraded injects pressure filter and carries out press filtration, and the mud after press filtration is got rid of, remaining clear liquid stores in receiving tank, afterwards clear liquid is injected electrolyzer electrolysis 3 hours with copper removal, this electrolytic process can be 2 ~ 4 hours, and gained solution can discharge afterwards.
The above is only the preferred embodiment of the present invention; be not limited to the present invention; should be understood that; for those skilled in the art; under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
