Embodiment 1

[0013] In the method of quickly reducing the chroma of printing and dyeing wastewater by using white rot fungi in this embodiment, the white rot fungi are collected from the wood of Pythium albicans, the white hyphae are stripped, and inoculated on the sterilized white rot fungus primary screening nutrient solution, Put it in an incubator at 39°C and cultivate it for 3 days. After the colonies grow, they will be separated and purified, and inoculated on the sterilized white-rot fungus re-screening medium, which can form guaiacol to change color and form a color Circle to determine the white rot fungi. White-rot fungi have many advantages in one, and their degradation functions are characterized by high efficiency, low consumption, broad spectrum, and strong applicability. They are different from general microorganisms and are promising organisms in environmental governance. Because white rot fungi degrade pollutants, they require low nutritional requirements, can tolerate high...

Abstract

The invention discloses a method for rapidly reducing the chromaticity of printing and dyeing wastewater by utilizing white rot fungi. First, the film is hung, and after the biofilm is mature, the whole reactor officially enters the operation stage, and 1 L of printing and dyeing wastewater is added, so as to realize the color change of the printing and dyeing wastewater. degree reduction operation. The treatment method of the invention can completely degrade various synthetic dyes into CO2 and H2O, also has good effect on decolorization of dye wastewater, and is of great significance to environmental protection and sustainable development in my country.

Description

technical field [0001] The invention relates to a method for rapidly reducing the chroma of printing and dyeing wastewater by using white rot fungi. Background technique [0002] Among all industrial wastewater, dye wastewater from dye industry and printing and dyeing industry is one of the most difficult industrial wastewater to treat, because dye is a compound with complex chemical structure, which contains artificially synthesized complex aromatic hydrocarbon molecular structure , is difficult to remove. According to reports, there are about 100,000 types of commercial dyes, and the total output of dyes per year is 7×10 5 t, my country's annual output has reached 1.5×10 5 t, about 10% to 15% of the dyes will be directly discharged into the environment with the wastewater, and this phenomenon is more serious in our country. Dyes are highly stable, difficult to be biodegraded, and can remain in the environment for a long time. The color of dyes is the reason for the high ...
