Excrement and urine separation super-water-saving toilet and use method

The invention provides an excrement and urine separation super water-saving toilet and a use method, and belongs to the technical field of sanitary facilities. The toilet comprises an excrement and urine separating system, a residual excrement cleaning system and an eccentric rotating wheel excrement overturning system, the excrement and urine separating system comprises a urine collecting area and an excrement collecting area, the residual excrement cleaning system comprises two sets of flushing systems, and the eccentric rotating wheel excrement overturning system drives an eccentric rotating wheel to rotate by means of the gravity of excrement. Loosening and closing of the eccentric rotating wheel are controlled through a clamping ratchet wheel, the rotating angle of the rotating wheel is accurately controlled through a 120-degree ratchet wheel, and therefore waterless conveying of excrement is achieved; a water tank is connected with a spray washing ring and a water jet nozzle, a small amount of flowing-o
