The invention discloses a rural domestic sewage treatment system, which comprises sequentially connected grids, regulating pools, anaerobic pools, aerobic pools and artificial wetlands, wherein the grids are connected with sewage pipes to intercept sewage in sewage pipes Suspended and floating pollutants; the regulating tank is used to adjust the water quality and water quantity of the sewage discharged from the grid; the sewage discharged from the regulating pond undergoes anaerobic reaction in the anaerobic pond; the sewage discharged from the anaerobic pond is discharged in the aerobic pond The aerobic reaction is carried out in the aerobic pool; the sewage discharged from the aerobic pool enters the constructed wetland, and the constructed wetland removes one or more of nitrogen, phosphorus, organic matter, pathogens, and solid substances suspended in the water in the sewage discharged from the aerobic pool. Constructed wetland effluent discharge. The invention can effectively treat rural domestic sewage, and has low technical requirements, simple structure, small occupied area, low cost, flexible adjustment, high treatment efficiency and good treatment effect. |
