Abstract

The invention discloses a compound halophilous-microorganism bacterium agent and an application thereof. Halophilous microorganisms are the microorganisms which are not inhibited or poisoned by high-concentration inorganic salts in the high-salt environment, can carry out normal growth and metabolism and comprise salt-resistant microorganisms and halophilic microorganisms. The compound halophilous-microorganism bacterium agent at least comprises two of halophilic bacteria, halophilic archaea, salt-resistant bacteria, salt-resistant archaea, halophilic fungi and salt-resistant fungi, wherein the types and the quantity of the halophilous microorganisms are at least 10, and the halophilous microorganisms at least comprise one type of uncultured microorganisms. The compound halophilous-microorganism bacterium agent disclosed by the invention has the advantages that high-efficiency and stable degradation can be carried out on organic matters under the condition of 1%-20% salt; by using the compound halophilous-microorganism bacterium agent for biochemical treatment of high-salt waste water and microorganism restoration of saline-alkaline soil, the pollution treatment cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental protection microorganisms, and in particular relates to a compound halo-suitable microbial bacterial agent capable of efficiently and stably degrading organic pollutants in a high-salt environment and an application thereof. Background technique [0002] The composition of high-salt wastewater is complex, and the inorganic salts in it can inhibit or poison the growth of common microorganisms, which seriously limits the application of biochemical technology in the field of high-salt wastewater treatment. Physicochemical treatment technologies including evaporation, membrane separation, ion exchange, advanced oxidation, electrolysis, etc., do not treat pollutants thoroughly or have high costs. Biochemical treatment of high-salt wastewater is theoretically feasible, but it is currently in the stage of laboratory research. The difficulty and key point of biochemical treatment technology for hig...
