The invention relates to a urine and excrement recycling device used in a train. A filter layer is installed in the middle of a discharge pipe. A water diversion pipe is arranged below the filter layer. A press drying device and a waste water treatment device are installed at the outlet end of the discharge pipe. A pressure boosting device and a pressure boosting pipe are connected to one end of the waste water treatment device. The pressure boosting pipe is connected with a toilet bowl water inlet pipe. As the filter layer is installed in the middle of the discharge pipe, the water diversion pipe is arranged below the filter layer, and the press drying device and the waste water treatment device are installed at the outlet end of the discharge pipe, urine and excrement in the discharge pipe can be separated. Excrement enters the press drying device and undergoes treatment, and then enters a charging belt. Urine and waste water enter the waste water treatment device and undergo treatment, and enter the pressure boosting device and then the pressure boosting pipe connected with the toilet bowl water inlet pipe for cyclic utilization. Therefore, urine and excrement are recycled in a separated manner, and environmental pollution and the spread of diseases are avoided.
