The Specific Application of Soil Microbial Environmental Remediation Technology
A study was conducted on the remediation technology of petroleum hydrocarbon(TPHs)contaminated soil using persulfate(PS)oxidation and microbial technology β-Cyclodextrin is used as a supplement to chelate Fe2+ and activate PS,while functional bacteria(GZ6)are added to further improve the degradation efficiency of TPHs.By studying the changes in TPHs enzyme activity and degradation rate,this study aims to investigate the remediation mechanism of PS oxidizing microbial remediation schemes on contaminated soil TPHs.The results showed that the PS oxidizing functional bacteria remediation scheme(CMB)can achieve a degradation rate of over 80％ for soil TPHs.The addition of GZ6 functional bacteria activated the TPHs degrading bacteria in the soil sink,further increasing the number of microorganisms in the soil and enhancing the degradation effect of TPHs.
