Halophilic decontamination bacterium and application thereof

Abstract

A halophilic decontamination bacterium and application thereof belong to the technical field of biological treatment of salinity wastewater. The halophilic decontamination bacterium strain was collected in China General Microbiological Culture Collection Center (CGMCC), with collection number of CGMCC No.3314. The halophilic decontamination bacterium strain is applied to preparing microbial agents and then the microbial agents are used for treating salinity wastewater or treating wastewater after seawater utilization. The invention adopts the bioaugmentation technology, greatly improves the capability of treating salinity wastewater and has low cost and significant effects.

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...

AI Technical Summary

Problems solved by technology

Known technologies cannot solve the problem of purification and treatment of saline wastewater, while bioaugmentation treatment technology has the characteristics of high efficiency, stability, and investment saving. Therefore, the development of high-efficiency bacteria and bacteria agents is the expectation of the industry, and the market urgently needs a microbial salt-tolerant cleaner. Biofouling agent developed to provide new way to purify seawater
