Abstract

The invention discloses a salt-resistant ammonia-nitrogen-removing compound bacterial agent for printing and dyeing wastewater treatment. The salt-resistant ammonia-nitrogen-removing compound bacterial agent is prepared from, by mass, 5-8% of a saline-alkaline-resistant aliidiomarina haloalkalitolerans culture, 5-7% of a salt-resistant nesterenkonia halotolerans culture, 20-22% of a zobellella taiwanensis culture, 15-18% of a comamonas aquatica culture, 10-12% of a pseudomonas putida culture, 10-15% of a bacillus subtilis culture, 5-7% of an arthrobacter simplex culture and 17-18% of an enterobacter cloacae culture. The salt-resistant ammonia-nitrogen-removing compound bacterial agent for the printing and dyeing wastewater treatment contains various strains, is reasonable in compatibility,has a strong synergistic effect, can effectively remove ammonia nitrogen and industrial COD in printing and dyeing wastewater, has low input cost, and can be promoted and used on a large scale.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing wastewater treatment, in particular to a salt-tolerant ammonia nitrogen removal compound bacterial agent for printing and dyeing 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. 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. [0003] For a long time, sewage biological treatment technology has been the main technology in the field of sewage treatment because of its unique technical, economic and environmental advantages. In continuous research and development, a series of sewag...
