Abstract: A biofilm composite carrier and a preparation method and use thereof are provided. The biofilm composite carrier includes a polyurethane framework, an adhesive and a functional material, wherein the functional material is adhered to the surface and pores of the polyurethane framework through the adhesive, and the functional material is a mixture of zeolite and tourmaline. The biofilm composite carrier is beneficial to the quick start-up and stable operation of the municipal sewage deammonification system under conditions of low temperature and low ammonium.
