Abstract

The invention relates to the technical field of sewage treatment, in particular to a composite microbial strain for degrading "triphenyl" waste gas and a preservation and activation method thereof. The complex microbial species include Bacillus, Pseudomonas, Streptococcus, Rhodococcus and Brevibacterium. The preservation method comprises the following steps: A1, inoculating the compound microbial strains for degrading "triphenyl" waste gas in a sterile enrichment medium at an inoculum amount of 9-11%, and cultivating by shaking to obtain a bacterial liquid; A2, taking the bacterial liquid , protective agent and active stabilizer, mix well and store at -78-82°C. The composite microbial strain of the present invention can efficiently degrade "triphenyl" waste gas, the preservation method is simple and easy to control, and the cost is low, and the activation of the composite microorganism after preservation can maintain a good "triphenyl" degradation ability, which can be benzene series The practical engineering application of waste gas biological treatment can quickly provide microbial strains with high activity to degrade benzene series.

Description

technical field

[0001] The invention relates to the technical field of sewage treatment, in particular to a composite microbial strain for degrading "triphenyl" waste gas and a preservation and activation method thereof. Background technique

[0002] In the prior art, the microbial strains that degrade "triphenyl" waste gas are not ideal for the degradation of "triphenyl" waste gas, and the preservation process of microbial strains is often accompanied by a decline in production activity, long adaptation time, and slow growth Therefore, the use of routinely preserved microbial strains in the bioremediation process often requires a long-term debugging process, and sometimes even the restoration effect is not good. Therefore, it is an inevitable requirement for bioremediation to obtain high-activity composite microbial strains that degrade "triphenyl" waste gas, and to preserve and activate the high-activity strains.
