Rural domestic wastewater treatment process

The invention relates to a domestic sewage treatment technology, and in particular relates to a rural domestic wastewater treatment process. After large impurities are removed by virtue of fine screen of a screen well, sewage enters into a regulating tank, and a perforated aerator pipe is arranged inside the regulating tank for aerating and stirring, so that the sewage is homogenous in quality and quantity; then the sewage automatically flows into an anaerobic-aerobic tank (A/O); due to the functions of aerobic and aerobic microorganisms, organic matters are decomposed into CO2 and H2O so as to remove most organic matters, and nitrification liquid from the tank O returns into the tank A to remove ammonia nitrogen; water discharged from the tank O automatically flows into a secondary sedimentation tank to remove suspended solids; and water from the secondary sedimentation tank is discharged on standard. The wastewater treatment process disclosed by the invention is high in removal efficiency, stable in operating performance and low in treatment cost.
