Ecological greenbelt treatment process and system for treating rural domestic sewage

The invention relates to an ecological greenbelt treatment process for treating rural domestic sewage, which mainly comprises the steps of: (1) anaerobic pretreatment: performing anaerobic hydrolysis pretreatment to domestic sewage; (2) artificial wetland treatment: performing artificial wetland treatment to pretreated domestic sewage; and (3) shallow ecological pond aerobic biotreatment: further performing shallow ecological pond aerobic biotreatment to outlet water treated by the artificial wetland, degrading and converting organic matters and nutrients entering the pond, and recycling purified sewage as a regenerated water resource. The invention adopts an ecological greenbelt treatment system comprising the anaerobic pretreatment, the artificial wetland and the shallow ecological pond to treat the rural domestic sewage, and has the characteristics of good treatment effect, recycling on site, low investment, low system operating cost, simple maintenance, obvious ecological benefit and the like.
