The invention discloses a biological agent for fixing pseudomonas aeruginosa PS1 by a silkworm excrement carrier and application of the biological agent. The pseudomonas aeruginosa PS1 is high in PAEs degradation capacity, the degradation rate of DBP reaches 97.5%, the degradation rate of DEHP reaches 60.2%, and various PAEs such as catechol, BA, PCA, PA, MBP, monobutyl benzoate, 4, 5-dihydroxyphthalic acid, DEP, DMP and DOP can be used as substrates. The biological agent which is prepared by taking silkworm excrement as a carrier for fixing pseudomonas aeruginosa PS1 and is used for repairing the environment polluted by PAEs is used for remarkably improving the pH value of soil, increasing the content of organic matters in the soil and/or increasing the content of nitrate nitrogen and/or ammonium nitrogen in the soil, improving the abundance of proteobacteria and/or digestion spirillum, and/or reducing the abundance of actinomycetes and/or Pseudonardiales. Therefore, the environment polluted by the PAEs is r
