Problems solved by technology

When using conventional biological treatment methods to treat printing and dyeing wastewater, there are problems that microorganisms are easily inhibited or poisoned, and the effluent indicators are unstable after treatment. Therefore, what method should be adopted to strengthen biological treatment to improve the toxicity resistance and treatment efficiency of printing and dyeing wastewater? It has become a hot spot in biological treatment of printing and dyeing wastewater in recent years

Abstract

The invention discloses a printing and dyeing wastewater biological treatment accelerant, as well as a preparation method and application thereof, and belongs to the field of wastewater treatment. The accelerant is prepared from cane sugar, urea, sodium acetate, dipotassium phosphate, zinc chloride, vitamin B12 and vitamin C. When the accelerant is added into a conventional biological treatment system, the co-metabolism of microorganisms can be quickly started, and the toxic tolerance of the biological treatment system on printing and dyeing wastewater can be improved. The printing and dyeing wastewater biological treatment accelerant is particularly adaptive to the characteristics of the printing and dyeing wastewater including high content of organic pollutants, high alkalinity and large water quality change, and can be used for effectively treating printing and dyeing wastewater.

Description

technical field [0001] The invention relates to the preparation and application of a biological treatment accelerator, in particular to a printing and dyeing wastewater biological treatment accelerator and its preparation method and application, belonging to the field of wastewater treatment. 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. Printing and dyeing wastewater has a large amount of water, 100-200 tons of water is consumed per ton of textile printing and dyeing, and 80-90% of it becomes wastewater. Printing and dyeing wastewater contains dyes, pastes, additives, oil agents, acids and bases, fiber impurities, sand substances, inorganic salts, etc., and has the characteristics of large water volume, high content of organic pollutants, large alkalinity, and large changes in water quality. One of the difficult industrial...
