The invention discloses a disposable feces treatment system with energy-saving, environment-friendly and ecologic recycling functions. The system is characterized in that the treatment system comprises a pigsty system, a solid and liquid separating system and a solid and liquid treatment system, wherein the pigsty system adopts a greenhouse structure, the bottom of a pigsty is provided with a feces leaking plate, the solid and liquid separating system is arranged under the pigsty, the bottom of the solid and liquid separating system is provided with an automatic control system, the liquid treatment system of the solid and liquid separating system consists of a concentration tank and a biogas tank, and the solid treatment system sequentially consists of a feces stirring machine, a fermentation tank, a turning and throwing device, a pressing device, a push and pull device and a packaging machine. The feces in the pigsty are separated and treated to form biogas and fertilizer, and then the recycling and reutilization can be realized. The feces treatment system has the advantages that the clean and sanitary level of the pigsty is fully improved, the environment of the pigsty is improved, the zero emission of feces and urine is truly realized, and the system is suitable for various types of culturing farms.
