The invention provides an integrated rural domestic sewage treatment device and method. The integrated rural domestic sewage treatment device comprises an inverted-cone-shaped pretreatment device, an anaerobic zone, an aerobic zone, a first hollow cylinder, a second hollow cylinder and an inverted-cone-shaped sludge zone. The second hollow cylinder is positioned in the first hollow cylinder; the pretreatment device is mounted on the second hollow cylinder, and the upper bottom of the inverted cone of the sludge area is connected with the lower end of the first hollow cylinder; a space between the first hollow cylinder and the second hollow cylinder is an aerobic zone, and the interior of the second hollow cylinder is the anaerobic zone; sewage firstly enters the pretreatment device, the settled sewage overflows from the periphery of the pretreatment device to enter the anaerobic zone, pollutants are partially degraded under the action of microorganisms in the anaerobic zone and then enter the aerobic zone fro
