NOVELTY - Automatically separating, collecting and recycling urine comprises (i) setting urine water and automatic separation type urinal, (ii) installing a urine collection pipeline and a flushing water discharging pipeline at a urine water outlet and automatic separation type urinal, (iii) arranging a urine storage chamber, a drug adding stirring device and a precipitate and liquid supernatant separation device in the urine collection pipeline, (iv) taking the precipitate as fertilizer, and (v) enabling the urine flushing water and the liquid supernatant to enter a lye treatment system.    USE - The method is useful for automatically separating, collecting and recycling urine.    ADVANTAGE - The method is simple, economical, environmental friendly; and recycles domestic sewage, and the nutritive substances e.g. nitrogen and phosphorus.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for device for automatically separating, collecting and recycling urine, comprising a urinal, a pipeline, a urine storage chamber, a drug adding stirring device, a precipitate and liquid supernatant separation device, a lye treatment system, and an automatic control device. The urinal is provided with a urine water automatic separation system. The urine water automatic separation system is controlled by the automatic control device. A discharging port of the urinal is connected with two pipelines including a urine collection pipeline and a flushing water discharging pipeline. The downstream of the urine collection pipeline is connected with the urine storage chamber, the drug adding stirring device, and the precipitate and liquid supernatant separation device. The discharging port of the precipitate and liquid supernatant separation device is connected with the lye treatment system. The outlet of the lye treatment system is connected with a wetland or a water storage pond.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the device for automatically separating, collecting and recycling urine.
