Manufacturers of polyacrylamide agents in Yancheng City printing and dyeing wastewater by PAM. Printing and dyeing wastewater is processing cotton, linen, chemical fiber and blended products of the printing and dyeing factory discharged wastewater. So far, various decolorization method from the economic, technical, the impact on the environment and practical considerations have certain defects. Adsorption decolorization of dye adsorption is only, but do not destroy the structure of the adsorbent, but recently used often exists adsorption capacity is not enough, or not easy defect regeneration. After many experiments we use polyacrylamide and cationic Decolorizing Flocculant to out sewage.
The use of flocculation and precipitation polymerization aluminum chloride as decoloring agent. Flocculation is one of the important means of industrial wastewater treatment, often using inorganic coagulant iron salt, aluminum salt and calcium salt, via colloidal particles and water electric neutralization, decreased the ZETA potential on the surface of particles, the compression of electric double layer, which attract each other and generate small floc, and then through the action of polymer flocculant bridge, swept volume, so that the small flocs becomes large, so as to achieve the purpose of rapid separation and purification. Some reactive dyes, dye intermediates and other industrial colored wastewater due to its hydrophilic water soluble dyes and complex structure, treatment with chemical flocculation in general, it is difficult to achieve the good effect of flocculation, adsorption and ozone oxidation method has certain effect on the decolorization of water soluble dye wastewater treatment, but the high cost of. Therefore, dye wastewater, especially red decolorization is a big problem in printing and dyeing wastewater treatment. In order to solve the problem of Decolorizing Flocculant Using dedicated.
So what is the use of the principle of Decolorizing Flocculant?
The use of flocculation and will produce compression of electric double layer, the suspended particles in the wastewater to lose stability, colloidal matter mutually to cause particles increases, the formation of flocs, alum. The flocs after growing to a certain volume under the action of gravity from the water phase precipitation, resulting in the removal of large amounts of suspended solids in waste water.
Decolorization and use method is simple, make us the most common use of printing and dyeing wastewater treatment agent
