Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention is not limited thereto.

[0040] An ecological green land treatment process for treating rural domestic sewage, the treatment process is mainly composed of anaerobic pretreatment steps, constructed wetland treatment steps and shallow ecological pond aerobic biological treatment steps:

[0041] (1) After passing through the septic tank, rural domestic sewage enters the grid well to remove large suspended particles, and then enters the regulating tank to adjust the water volume and homogenize the water quality.

[0042] (2) The effluent from the regulating tank enters the anaerobic pretreatment system after being lifted by the pump, and undergoes biochemical treatment in the anaerobic membrane bioreactor.

[0043] (3) The effluent after the anaerobic pretreatment system is lifted by the pump and enters the c...

Abstract

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.

Description

technical field [0001] The invention relates to a process and system for treating domestic sewage in rural areas, in particular to a treatment technology and system for combining artificial wetlands and shallow ecological ponds for treating domestic sewage in rural areas, and belongs to the field of environmental protection and water pollution control. Background technique [0002] With the development of my country's industrial and agricultural production and population growth, the problem of environmental pollution has become increasingly serious. At present, most domestic sewage in rural areas of our country is directly discharged without any sewage collection and treatment, causing pond and river pollution, which not only affects the living environment of villagers, but also seriously threatens the health of farmers. The common problems in rural areas are: scattered and large population, weak infrastructure construction, imperfect drainage system and sewage treatment con...
