Integrated treatment device and treatment method for kitchen garbage and excrement waste water

The invention relates to an integrated treatment device and an integrate treatment method for kitchen garbage and excrement waste water. The integrated treatment device comprises a material mixing tank, a two-phase anaerobic processor, a water outlet settling tank and a boiler, wherein a small stirrer is mounted in the material mixing tank; the two-phase anaerobic processor is sequentially divided into an acid producing area, a transitional area and a methane producing area by an overflow plate and a transitional plate; the transitional area is positioned between the acid producing area and the methane producing area and is used for separating the acid producing area from the methane producing area; a large stirrer is mounted in the methane producing area; an acid producing area stirrer is mounted in the acid producing area; a transitional area stirrer is mounted in the transitional area; an acid producing area sampling opening and a methane producing area sampling opening are respectively formed in the side wall of the two-phase anaerobic processor in the acid producing area and the methane producing area; the material mixing tank is connected with the acid producing area of the two-phase anaerobic processor through a feeding pipe; the water outlet settling tank is connected with the methane producing area of the two-phase anaerobic processor through a water overflow pipe; a biogas collecting pipe is arranged at the top end of the two-phase anaerobic processor in the methane producing area; a biogas collecting bag is connected with an air inlet of the boiler.
