The present disclosure provides a nanocomposite for microbial remediation and a preparation method and use thereof. The preparation method includes the following steps: (1) preparation of a Paracoccus aminovorans bacterial cell; (2) preparation of an 5 embedding agent graphene oxide-based nanocomposite; (3) preparation of a crosslinking agent CaCl2 solution; and (4) preparation of a nanocomposite for microbial remediation. In the present disclosure, a prepared immobilized microbial remediation agent of graphene oxide-based nanocomposites has strong 10 applicability to the environment, ensures a stable performance of a degradation function of polycyclic aromatic hydrocarbons (PAHs) degradation microorganisms, improves a degradation efficiency of traditional immobilized microbial preparations, and shortens a cycle of microbial remediation on PAHs-contaminated soil; the 15 preparation method has simple operations, low costs and desirable effects, has a prospect of large-scale industrial production, and is suitable for in-situ remediation of the PAHs-contaminated soil without secondary pollution.
