Undivided paired direct electro-oxidation and electro-reduction reactor utilizing activated carbon fiber electrode

Abstract

The invention provides an undivided paired direct electro-oxidation and electro-reduction reactor utilizing an activated carbon fiber electrode. The reactor comprises a first insulation board, wherein the inner side of the first insulation board is fixedly connected with a first electrode pad, a first activated carbon fiber end electrode, a first electrode chamber, an activated carbon fiber common electrode, a second electrode chamber, a second activated carbon fiber end electrode, a second electrode pad and a second insulation board by bolts in sequence; and sealing rings are arranged at twosides of the first electrode chamber and the second electrode chamber. According to the invention, electrolytic decolorizing is realized through the direct electro-oxidation and electro-reduction action generated among the activated carbon fiber electrodes of the first activated carbon fiber end electrode, the activated carbon fiber common electrode and the second activated carbon fiber end electrode, the current efficiency and decolorizing efficiency can be improved and energy consumption can be reduced, thus realizing the high-efficiency and low-consumption decolorizing treatment of dye industrial wastewater and printing and dyeing wastewater.

Description

【Technical field】 [0001] The invention relates to a processor of dyestuff industrial wastewater and printing and dyeing wastewater, in particular to a paired direct electro-oxidation-electro-reduction reactor with activated carbon fiber electrodes without a diaphragm. 【Background technique】 [0002] my country is a big country in the production and application of dyestuffs (including textile printing and dyeing). There are more than 500 kinds of dyestuffs in production, and all kinds of dyestuffs are produced. The annual output reaches 40,000 tons, accounting for 45% of the world's total output. For every ton of dye produced, 2% of the product will be lost with wastewater. Printing and dyeing wastewater is an important source of pollution in the textile industry. During the dyeing process, about 10% of the dye is lost with the wastewater because it is not dyed. The wastewater discharge of my country's textile printing and dyeing industry is about 300-400×106m3 / d. The decolo...
