Benefits of technology

This patented technology allows for effective use of an organism called Bacillus spores (Bacillusssp.) when treating different types of industrial or commercial wastes such as those containing dichroinsulfonate dyestuffs. It also includes various methods used during manufacturing processes to make it more efficient at decompositing these chemical substances into harmless materials like nitrosothiazole sulfonic ammoniums). Overall, this new biological material provides technical benefits including improved ability to remove colored contaminants from aqueous solutions without causing environmental harm while maintaining their original properties.

Problems solved by technology

This patents discusses different ways for treating or removing harmful substances from dyed materials like paper pulp during manufacturing processes. Chemistry method requires expensive equipment that may be limited with regards to changing conditions over time and does little work at all if there are many other compounds found within them. Biology techniques have shown promise but they also face challenges when dealing with various colored agents used in these industries.

Abstract

The invention discloses a compound microbial agent for treating dye waste water as well as preparation and application of the compound microbial agent. The compound microbial agent is formed by complexing acinetobacter haemolyticus, Escherichia coli, bacillus flexus, Yersinia intermedia, luther enterobacter and Klebsiella pneumoniae. Complexing is simple and convenient, the broad spectrum is strong, the difficulty that a single microbial agent can not meet the requirement of water quality variation is overcome, and the cost of treating the dye industrial waste water is reduced.
