Abstract

The invention provides a wastewater automatic decoloring device which comprises a filter tank, wherein the filter tank is communicated with a first sedimentation tank; the first sedimentation tank iscommunicated with a decoloring tank; the decoloring tank is communicated with a decoloring agent generating device through a third control valve; the decoloring agent generating device comprises a formaldehyde dropping device, a reactor, a urea dropping device, a catalyst dropping device, a heater and a master controller; the formaldehyde dropping device, the urea dropping device, the catalyst dropping device and the heater are all controlled by the master controller. The wastewater automatic decoloring device provided by the invention can realize automatic preparation of a decoloring agent, and thus can realize a total automatic process of wastewater treatment together with other technologies of wastewater treatment.

Description

technical field [0001] The invention relates to the field of environmental protection machinery, in particular to an automatic decolorization device for waste water. Background technique [0002] Printing and dyeing wastewater is wastewater discharged from printing and dyeing factories that mainly process cotton, hemp, chemical fibers and their blended products. [0003] Printing and dyeing wastewater has a large amount of water, 100-200 tons of water is consumed per ton of textile printing and dyeing, of which 80-90% becomes wastewater. [0004] 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. [0005] The main methods used to treat printing and dyeing wastewater include physical and chemical methods, biochemical methods, chemical meth...
