Embodiment Construction

[0028] The present invention will be further described below in conjunction with specific embodiments.

[0029] An organic-inorganic composite high-efficiency decolorizer, consisting of component 1, component 2, and component 3, wherein:

[0030] Component 1 is composed of the following components by mass percentage:

[0031]

[0032] The remainder is water;

[0033] The preparation method of the component 1 is as follows: prepare each agent according to the mass ratio, take 50-70% of the whole formaldehyde solution as a solvent, add the solute dicyandiamide, ammonium chloride and catalyst into the solvent, Dissolve at a constant temperature of 70°C. After the solute is completely dissolved, add the remaining 30%-50% formaldehyde solution; the constant temperature reaction time is 3-8 hours, then add a chain extender, react for 0.5h, and cool to obtain a colorless, transparent, Viscous liquid, namely component 1.

[0034] Preferably, the constant temperature reaction tim...

Abstract

The invention discloses an organic-inorganic composite efficient decolorizing agent which is characterized by being composed of the following components: a component 1, a component 2 and a component 3, wherein the component 1 contains 35-55% of dicyanodiamine (n-cyanodiamine, dicyandiamide, chemical formula:C2H4N4), 10-35% of ammonium chloride, 5-50% of formaldehyde solution containing 35-40% of formaldehyde, 1-5% of catalyst, 0.5-1% of chain extender and the balance of water, the component 2 is a coagulation aid; the component 3 is polyacrylamide. The invention also discloses a using method of the organic-inorganic composite efficient decolorizing agent. The organic-inorganic composite efficient decolorizing agent disclosed by the invention has the beneficial effects that the decolorizing effect is good; the catalyst is added in the decolorizing agent, so that the reaction efficiency is increased, and the preparation time of the decolorizing agent is shortened; the chain extender is added, so that the treating capability of the decolorizing agent is enhanced; the decolorizing agent is convenient to use and operate and easy to popularize.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to an organic-inorganic composite high-efficiency decolorizer and a method for using the same. Background technique [0002] Textile printing and dyeing wastewater has the characteristics of large water volume, high content of organic pollutants, many refractory substances, high chroma, and complex components. It is a difficult-to-treat industrial wastewater. The printing and dyeing industry is a large industrial wastewater discharge. Consumers' increasing requirements for printing and dyeing processing, and the wide application of a large number of new printing and dyeing auxiliaries, functional dyes, and pastes have resulted in more and more complex and changeable organic matter components in printing and dyeing wastewater, which has become a key issue that plagues printing and dyeing wastewater treatment. [0003] At present, the treatment of printing and dyeing wastewater generall...
