Printing and dyeing sewage treatment equipment

Abstract

The invention discloses printing and dyeing sewage treatment equipment. The printing and dyeing sewage treatment equipment comprises a base, wherein a filter box is fixedly connected to the left sideof the top of the base; the inner cavity of the filter box is provided with a filter plate, an activated carbon adsorption plate and a sand and stone filter plate in sequence from top to bottom; the left side of the inner cavity of the filter box as well as the top and bottom of the filter plate are fixedly connected with sealing sleeves. Through arrangement of the activated carbon adsorption plate and the sand and stone filter plate, the effects of filtering and adsorbing sand and activated carbon in the sewage are achieved. Through arrangement of a water pump, the effect of disinfecting thesewage by sucking and discharging disinfectant fluid from the inner cavity of a disinfectant fluid tank to the inner cavity of the disinfection tank is achieved. Through arrangement of a motor, a stirring rod and stirring blades, uniform stirring of the sewage is realized, and the disinfectant fluid can be used for fully disinfecting the sewage. Through arrangement of a high-temperature heating pipe, the effect of high-temperature disinfection of disinfected water is achieved.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing sewage treatment, in particular to a printing and dyeing sewage treatment equipment. Background technique [0002] Printing and dyeing wastewater is the wastewater discharged from printing and dyeing factories that mainly process cotton, hemp, chemical fibers and their blended products. The amount of printing and dyeing wastewater is relatively large. Each ton of textile printing and dyeing consumes 100 to 200 tons of water, of which 80 to 90% become wastewater. Textile printing and dyeing wastewater has the characteristics of large water volume, high content of organic pollutants, high alkalinity, and large changes in water quality. It is one of the most difficult industrial wastewater to treat. Impurities, sand substances, inorganic salts, etc. Printing and dyeing wastewater is recognized as one of the more difficult industrial wastewater at home and abroad. It has the characteristic...
