Abstract

The invention discloses a method for degrading triphenyl phosphate through brevibacillus brevis and application thereof and belongs to the technical field of environment organic pollutant biotreatment. The method specifically comprises the steps that a degradation culture medium with triphenyl phosphate as a unique carbon source is inoculated with the brevibacillus brevis under the condition that the temperature is 30 DEG C; five days after degradation of a constant-temperature shaking table, the concentration of the triphenyl phosphate left in the culture medium is measured through a gas chromatography-mass spectrometer (GC-MS), and in this way, the degrading effect of the brevibacillus brevis on the triphenyl phosphate is analyzed. According to the method, environment suitability of the method is high, and the cost is low; the degradation rate of organophosphorus fire retardant can reach 95.4% five days later. The actual application value is high, and a reference is provided for solving the problem of water organophosphorus fire retardant pollution treatment.

Description

technical field

[0001] The invention belongs to the technical field of biological treatment of environmental organic pollutants, and in particular relates to a method for degrading triphenyl phosphate by using bacillus brevis and an application thereof. Background technique

[0002] In recent years, brominated flame retardants (BFRs) have been gradually banned worldwide, and organophosphorus flame retardants (OPFRs) have gradually become popular due to their good flame retardant properties and low toxicity. Major substitute for BFRs, whose production and use have grown substantially. OPFRs are widely used in industries such as textiles, building materials, electronics, and chemical reagents. According to reports, the output of OPFRs in China reached 150,000 tons in 2013, and the annual growth rate is 15%. Since the way of adding OPFRs to materials is mainly direct addition rather than chemical bond synthesis, it is easy to be released into the environment during production ...
