Because the drain pump 8 is closed and the emptying valve 20 is opened at the same time, the reserved water in the water outlet pipeline 7 in the frozen soil layer 10 and above is quickly returned to the water supply system, the problems of freezing and pipeline breakage of the water outlet pipeline 7 penetrating through the frozen soil layer 10 and the part of the frozen soil layer on the ground are avoided, the service lives of the water outlet pipeline 7 and the emptying valve 20 are greatly prolonged, and meanwhile, the purposes of no use, no power consumption and energy conservation are realized.

As shown in fig. 1 to 5, the water supply system used in the above embodiments is a water collection tank 1 disposed in an anti-freezing soil layer 9, the water collection tank 1 is connected to an underground water supply system disposed in the underground anti-freezing soil layer 9, a drain pump 8 is connected to the water collection tank 1 for pumping water in the water collection tank 1 into a water outlet pipeline 7, and the water collection tank is supplied with water through a water supply system (the water supply system is not shown in the figure) to meet the flushing requirement.

In order to better utilize sewage or rainwater generated in life, the water collecting tank 1 is also connected with a sewage filtering device 40 positioned on the ground through a sewage pipeline 30, the water collecting tank 1 is used for collecting the filtered domestic sewage or rainwater, so that part of water resources are reused, a large amount of water resources are saved, and only when the domestic sewage, the rainwater and other waste water are not enough, the water supply system is started to inject tap water into the water collecting tank 1, so that the environment is protected.

In addition, the water supply system provided by the invention can also realize the automatic water storage function of the water collection tank 1. When the water level in the water collecting tank 1 reaches the lower limit, the water supply system can be driven to automatically store water, and when the water level is detected to reach the upper limit, the water storage is automatically stopped. Of course, in order to prevent the problem of overflow caused by excessive water stored in the water collection tank in the season of more rainwater, the invention arranges the water seepage well 6 in the underground anti-freezing soil layer, and the redundant water in the water collection tank 1 can naturally flow into the water seepage well 6 through the pipeline to be discharged, as shown in fig. 2, 4 and 5.

Because the normal-pressure water collecting tank 1 is adopted in the invention, the control switch 4 is started to start the drainage pump 8, the water feeding function of the water outlet pipeline 7 can be quickly realized, and a certain water pressure is generated at the water outlet position of the water outlet pipeline. When adopting backward flow type drain pump, directly return the water retention of outlet pipe way 7 and above region to header tank 1 in, the using water wisely greatly, its simple structure, installation and transformation low cost. The backflow type drain pump herein may employ a small-sized water pump, and may be commercially available.

In addition, the invention also provides the energy-saving sanitary environment-friendly toilet as shown in fig. 1 to 5, which comprises a septic tank 50, a urinal or a closestool 21 positioned on the ground and a flushing device connected with the urinal or the closestool 21, wherein the urinal or the closestool 21 is arranged above the septic tank 50, the septic tank 50 is positioned in the underground anti-freezing soil layer 9 and is connected with a feces outlet of the urinal or the closestool 21 through a lower pipeline 60, and a water outlet of a water outlet pipeline 7 is connected with a water inlet of the urinal or the closestool 21.
