Acidic dye wastewater treatment agent

Abstract

The invention discloses an acidic dye wastewater treatment agent, belonging to the field of sewage purification treatment. The treatment agent is prepared from polyaluminum chloride, ferrous sulfate, active silica, oxydol, activated carbon and chlorine dioxide. All the components are uniformly stirred and completely dissolved at room temperature. The application temperature is 4-60 DEG C. The acidic dye wastewater treatment agent is suitable for treating acidic sewage. The Fenton reagent composed of the ferrous sulfate and oxydol according to certain parts by weight is combined with the inorganic flocculant polyaluminum chloride to form the main component of the sewage treatment agent; by using the active silica as the assistant, the suspended substance are quickly settled under the synergistic actions of the Fenton reagent, main component and assistant; and the combination of the activated carbon and chlorine dioxide can implement quick disinfection, decolorization and sewage purification. The acidic dye wastewater treatment agent has the advantages of low treatment cost, no corrosiveness, no toxicity and no secondary pollution after treatment.

Description

technical field [0001] The invention belongs to the field of sewage purification treatment, and in particular relates to an acid dye wastewater treatment agent. Background technique [0002] Dye wastewater is one of the main harmful industrial wastewater, which mainly comes from the production industry of dyes and dye intermediates. It is composed of the mother liquor of crystallization of various products and intermediates, materials lost during the production process, and sewage from washing the ground. With the continuous growth of the dye industry, its production wastewater has become a major source of water pollution. [0003] my country is a big dye production country, and the textile dye industry has developed rapidly in recent years. According to the different characteristics of dyes, dyes can be classified differently. According to the chemical structure of dyes, dyes can be divided into: azo dyes, anthraquinone dyes, indigo dyes, sulfur dyes, cyanine dyes, triaryl...
