Abstract
Description
technical field The invention belongs to the technical field of biological treatment of salty wastewater, in particular to a salt-tolerant decontamination bacteria and its application. Background technique At present, many conventional physical, chemical and biochemical methods can be applied to the treatment of saline wastewater. There are large differences in treatment, especially the impact of high salinity, which increases the difficulty of sewage treatment. It has been found through research that the toxic effect of high concentration inorganic salts on wastewater biological treatment is mainly through the destruction of microbial cell membranes and enzymes in bacteria through elevated environmental osmotic pressure, thereby destroying the physiological activities of microorganisms. In addition, the salinity in the wastewater increases the density of the wastewater, resulting in a decrease in the specific gravity difference between the wastewater and the microorganism...
