The moving bed biofilm reactor is an improved novel composite biofilm reactor developed on the basis of a fixed bed reactor, a fluidized bed reactor and a biofilter. The method overcomes the defects that a fixed bed reactor needs regular back flushing, a fluidized bed reactor needs carrier fluidization, and a submerged biological filter is blocked and needs to be cleaned and an aerator needs to be replaced, and also keeps the characteristics of impact load resistance, low sludge yield and long sludge age of the traditional biofilm method. Compared with the activated sludge method, the method has longer sludge age, can keep more nitrifying bacteria and has better denitrification effect. The main principle is that after sewage continuously flows through a reactor filler carrier, a biological film is formed on the carrier, and microorganisms propagate and grow on the biological film in a large quantity and degrade organic pollutants in the sewage, so that the sewage is purified.
