The invention discloses a fluidized bed film bioreactor for sewage treatment, which belongs to the technical field of water and waste water treatment. The invention utilizes a process combining a biological fluidized bed with a film bioreactor, i.e. the reactor is filled with self-produced carrier granules with a diameter of about 5mm, wherein the carrier granules are made of waste rubber powder, activate carbon and adhesive, and the filling ratio is 10-30% of the effective volume of the reactor. By means of the synergistic effect of the carriers and sludge to finish the film forming process, microorganism is grown on the filler to reduce the concentration of the sludge in the reactor, change the environment running condition of the reactor and slow down the film pollution, thus further prolonging the service life of the film and improving the treatment capacity of the film. By filling the self-produced carrier granules in the film bioreactor and using the filler to change and regulate the interior microenvironment of the fluidized bed film bioreactor, such as dissolved oxygen (DO), the quantity of the filler and the water retention time, a local anoxic zone is formed, thus further realizing the synchronous nitration and denitrification function and improving the removal efficiency of total nitrogen as well as the denitrification efficiency. The fluidized bed film bioreactor for sewage treatment has a simple structure, does not feed the addition of chemical agent, is convenient and efficient to run and operate, can obtain high-quality outlet water, saves energy, can remove various pollutants such as organic matters, total nitrogen and the like, is suitable for treatment of organic waste water such as industrial and domestic waste water and the like, and can be hopefully applied in engineering practice.
