The application discloses a method for deep denitrification and phosphorus removal based on polylactic acid and pyrrhotite cooperation, which comprises the following steps: S1, activated sludge preparation; S2, activated sludge inoculation; S3, reaction component activation; S4, wastewater subsection treatment. In the method, polylactic acid is used as a heterotrophic denitrification solid carbon source, and pyrrhotite is used as an autotrophic denitrification electron donor for denitrification and phosphorus removal, a reaction component is built, and the activation method of the reaction component and the step parameters are defined in detail, so that the best treatment condition is obtained, and the polylactic acid-pyrrhotite composite filler is used for cooperation and denitrification, thereby realizing efficient wastewater denitrification and phosphorus removal.
