The invention belongs to the technical field of sewage treatment, and particularly relates to a domestic sewage environment-friendly treatment method, which adopts the following device to realize domestic sewage treatment: the device comprises a sewage treatment tank, a stirring device which is arranged in the sewage treatment tank and is used for realizing full mixing of activated sludge and domestic sewage, and a plurality of layers of inclined feeding pipes for pumping air, all the inclined feeding pipes incline in the same direction, and one-way valves for preventing sewage from entering the inclined feeding pipes are arranged in the inclined feeding pipes. According to the invention, through the design of an inclined stirring assembly, all-directional rapid uniform mixing of sewage and activated sludge can be realized, and air can be transported to each position of the sewage by cooperating with the design of the inclined feeding pipe, so that the adsorption and decomposition efficiency of the activated
