Description
Technical field
The present invention relates to the treatment process of the organic wastewater with high concentration of a kind of high pollution, high chroma, difficult degradation, especially be applicable to the treatment process of the hc effluent of tobacco sheet industry.
Background technology
The tobacco sheet industry has developed into a quite ripe industry abroad, and by international tobacco industry is widely used, the tobacco sheet industry develops at home and still is in the initial stage, and very large development potentiality is arranged.State Tobacco Monopoly Bureau had announced the Tar timetable in 2010, and tobacco sheets by paper making method was listed in to one of the field of giving priority to of countries tobacco industry " 12 plan ".Tobacco sheet is to utilize offal, offal and smoked sheet etc. discarded in the cigarette process to make the thin slice near tobacco leaf as raw material, is used further to production of cigarettes.Tobacco sheet can reduce the content of tar and Nicotine in process of production, becomes the important technique measure of reducing tar and reducing harm.In general, more than the single cigarette of mixing the High Quality Tobacco thin slice can reduce tar 3mg, the policy of domestic present stage was that every cigarette coke tar content can not surpass 12 milligrams, can not be over 10 milligrams by further dropping in 1 day January in 2015.Therefore, the critical role of tobacco sheet and effect will highlight more, and the economic benefit of this respect and social benefit are also very significant.
The waste water that produces in the tobacco sheets by paper making method production process contains a large amount of fiber fines, contain simultaneously and be rich in take polysaccharide as the main materials such as carbohydrate, tar, Nicotine, phenols, phenyl ring class, pectin, nicotine, lignin and solanone compounds, these compositions cause that tobacco wastewater COD concentration is high, colourity is high, difficult degradation, and wherein the material such as nicotine also has restraining effect to microorganism growth.
In the waste water of tobacco sheet production discharging, especially serious with the hc effluent pollution, its main source is soak solution, extracting solution, concentrated solution, and the water quality characteristics of hc effluent is:
(1) concentration is high: mixed COD concentration can reach 100,000 mg/l, or even 30 ~ 600,000 mg/l;
(2) colourity is dark: in hc effluent, contain high concentration sugar, protein, these structures of matter are stable, difficult degradation.
At present, domestic reconstituted tobacco production line has all been established corresponding waste water treatment engineering, mainly adopt at present the processing technological flow of " precipitation → anaerobism → aerobic biochemical → coagulation air-float ", these technical process are all by hc effluent and low density wastewater during combination treatment, the problem that the ubiquity working cost is high, effluent color dilution is high, water outlet COD is high, waste water can not reach first discharge standard.
Summary of the invention
The objective of the invention is to solve the deficiencies in the prior art, a kind of technique of utilizing electrochemical oxidation process to process tobacco sheet industry organic wastewater with high concentration is provided.
The objective of the invention is to be achieved through the following technical solutions: a kind of technique of utilizing electrochemical oxidation process to process tobacco sheet industry hc effluent, wherein, step comprises:

Supernatant liquor in step 2, step 1 enters the electrochemical oxidation reactions pond, carries out oxide treatment, and oxide treatment produces supernatant liquor and mud, and supernatant liquor mixes with low density wastewater during, enters low density wastewater during treatment system, and mud enters sludge treating system.
?Above-mentioned a kind of technique of utilizing electrochemical oxidation process to process tobacco sheet industry hc effluent, wherein, the coagulating agent in step 1 is selected from any one or a few in polymerize aluminum chloride, ferric sulfate, Tai-Ace S 150, aluminium iron polychloride, iron trichloride, ferrous sulfate.
Above-mentioned a kind of technique of utilizing electrochemical oxidation process to process tobacco sheet industry hc effluent, wherein, the flocculation agent in step 1 is polyacrylamide.
Above-mentioned a kind of technique of utilizing electrochemical oxidation process to process tobacco sheet industry hc effluent, wherein, electrochemical oxidation reactions pond in step 2 uses β-Pb02 or ruthenium-iridium-tantalum as anode, current density range is 30 ~ 70mA/cm2, in the electrochemical oxidation reactions pond, the pH scope of organic wastewater with high concentration is 3 ~ 7, between the electrolysis inch, is 20 ~ 60min.
In sum, owing to having adopted technique scheme, the present invention has following advantage and outstanding effect:
(1) can remove colourity in water fully, guarantee that the system effluent color dilution, less than 80 times, reaches first discharge standard;
(2) can remove hard-degraded substance in hc effluent, that improves whole system can biochemical ability;
(3) can reduce the load of whole system 20%, reduce by 20 ~ 30% running cost.
