The invention discloses an arsenic-containing and halogenated hydrocarbon-containing acidic composite contaminated soil remediation agent and method. The remediation agent comprises ferrate, pseudomonas, acinetobacter and bacillus. The remediation agent mainly utilizes ferrate to oxidize and decompose halogenated hydrocarbon and oxidize and stabilize arsenic, and meanwhile, organic halogenated hydrocarbon is degraded by utilizing microbial flora; through the synergistic effect of chemical oxidation and biodegradation, arsenic-containing and halogenated hydrocarbon-containing composite contaminated soil can be remediated; through mutual cooperation and mutual complementation, the addition amount of an oxidant is reduced, the remediation efficiency is improved, the content of the remediatedhalogenated hydrocarbon is lower than the screening value standard of 'soil environmental quality Risk control standard for soil contamination of development land (trial)' (GB 36600-2018), and the acid leaching concentration
