DETAILED DESCRIPTION - The system comprises an outlet of a crusher (1), discharging pipes of a toilet bowl, and sewage header pipes. A first biochemical system is provided with a first heating tank, a first biochemical tank, a first liquid storage tank and a first gas storage tank. The outlet of the crusher, the discharging pipes of the toilet bowl and the sewage header pipe are connected with the first heating tank, the first biochemical tank, the first liquid storage tank and the first gas storage tank. The first heating tank, the first biochemical tank, the first liquid storage tank and the first gas storage tank are connected through a first exhaust pipe and a first air storage tank. A second biochemical system is provided with a second heating tank, a second biochemical tank, a second liquid storage tank and the second gas storage tank. The second heating tank, the second biochemical tank, the second liquid storage tank and the second gas storage tank are connected through a second exhaust pipe and a second air storage tank. The second liquid storage tank is arranged into a first distributing pipe and a second distributing pipe. The output end of the first distributing pipe is connected with a liquid storage tower that is connected with an infusion pipe and an orchard. The output end of the second distributing pipe is connected with a farmland. The first heating tank and the second heating tank are provided with a solar energy heater using a solar energy and an electric energy.
