Abstract
The present invention discloses a novel composite decolorant. The technical scheme of the present invention is that the composite decolorant comprises, by weight, 10-20 parts of powder carbon, 5-10 parts of sodium hypochlorite, 5-10 parts of ferrous sulfate, 10-15 parts of dicyandiamide, 10-15 parts of formaldehyde, 5-10 parts of diatomite, 5-10 parts of poly aluminium chloride, 5-10 parts of sodium carbonate, 5-10 parts of fly ash, 1-5 parts of sodium aluminate, 10-15 parts of sodium hydroxide, and 1-3 parts of polyacrylamides, wherein the addition amount is controlled at 20-30 mg/L. Compared with the composite decolorant in the prior art, the composite decolorant of the present invention, has the organic synergistic discoloration effect of the adsorption discoloration and the oxidation discoloration so as to have the characteristics of low consumption, stable discoloration effect, and the like.
Description
Technical field
The present invention relates to discoloring agent technical field in wastewater treatment, particularly relate to the compound discoloring agent that high chroma in the trade effluent of dyeing, paper industry and pharmaceutical industry is removed in a kind of application.
Background technology
At present, the decolouring technology primary differentiation facture (as oxychlorination method, oxychlorination-ultraviolet method, Ozonation etc.) in wastewater treatment.Physical treatment process (as filtration treatment method, By Bubble-floating Method etc.).Physicochemical treatment method (as flocculation treatment, adsorption treatment, ion exchange method etc.) and several large type of biological treatment (as activated sludge process, anaerobic digestion etc.).The application of subject knowledge in waste water decoloring such as above-mentioned several large class facture i.e. synthetic chemistry, physics, electricity.Still there is following several respects problem at present in above-mentioned treatment process:
(1) waste water containing special coloring matter can not be processed,
(2) in sewage, its initial start-up of removal process of coloring matter takes and normal running cost etc.,
(3) decolorizing effect can not definitely ensure,
(4) in engineering, application is few at present.
Current patented technology mostly biases toward the more of flocculation decoloration or oxidative decoloration, and the such as patent No. is CN200710172989, CN201410710743 etc., is all some component based on changing discoloring agent, and then improves the efficiency of discoloring agent.Also novel the removing of flocculation combination attempted by some discoloring agent, and the Chinese patent literature being CN201410855525, CN200310115570, CN201210211006 as the patent No. discloses compound discoloring agent composition.But it is too much all to there is dosage in these discoloring agents, the problems such as decolorizing effect is unstable, so market is starved of one and not only can takes into account decolorizing effect and stablize now, and have dosage few compound discoloring agent.
Summary of the invention
In view of this, the technical problem to be solved in the present invention is to provide a kind of compound discoloring agent composition, and when discoloring agent composition provided by the invention is used for the trade effluent of dyeing, paper industry and pharmaceutical industry, not only amount of consumption of drugs is few, the removal function of good decolorizing effect.
For achieving the above object, this invention takes following technical scheme:
A kind of new type compound discoloring agent, with parts by weight, composed of the following components:
Powder carbon: 10 ~ 20, clorox: 5 ~ 10, ferrous sulfate: 5 ~ 10,
Dyhard RU 100: 10 ~ 15, formaldehyde: 10 ~ 15, diatomite: 5 ~ 10,
Polymerize aluminum chloride: 5 ~ 10, sodium carbonate: 5 ~ 10, flyash: 5 ~ 10,
Sodium aluminate: 1 ~ 5, sodium hydroxide: 10 ~ 15, polyacrylamide: 1 ~ 3.
Described compound discoloring agent preparation technology is: by proportioning, after the mixing of each component, dispersed with stirring evenly after finished product.
Compound discoloring agent of the present invention can be used for the removal of high chroma in the trade effluent of removal dyeing, paper industry and pharmaceutical industry, and controlling throwing amount is 20 ~ 30mg/L.
Compared with prior art, distinguishing feature of the present invention is the organic collaborative decolouring of adsorption bleaching and oxidative decoloration, so it is few to have dosing, and the features such as decolorizing effect is stable.
