Abstract

The invention aims to provide a microbiological degradation method for nitrobenzene industrial wastewater. According to experimental selection, composite bacteria liquid of Pseudomonas, Stenotrophomonas maltophilia, Acinetobacter baumannii, Aquaspirillum, Acidovorax avenae, Alcaligenes faecalis and Bacillus is provided. Domestication culture and three-stage amplification culture are carried out on the composite bacteria liquid so as to obtain a high efficiency composite microbial inoculum suitable for industrial production. When used to treat nitrobenzene wastewater, the microbial inoculum provided in the invention has the advantages of strong biological activity, long survival time, high capability in resisting impact load of influent quality and thorough treatment.

Description

technical field

[0001] The invention belongs to the technical field of pollutant biological treatment, and in particular relates to a treatment method for using microorganisms to degrade nitrobenzene industrial wastewater. Background technique

[0002] Nitrobenzene, with the molecular formula C6H5NO2, is an important chemical raw material widely used in industrial production such as the manufacture of aniline, explosives, lubricants, pesticides and spices. With the rapid development of human industrial production, a large amount of nitrobenzene has entered the natural environment. It is estimated that more than 10,000 tons of nitrobenzene are discharged into the environment around the world every year. Nitrobenzene is a highly toxic substance. After being absorbed by human skin or inhaling its vapor from the respiratory tract, it will cause poisoning or even death. There are extremely strict limits on reasonable discharge in wastewater. In my country, the "Comprehensive ...
