Embodiment

[0018] The comprehensive treatment method for rural domestic sewage of the present embodiment comprises the following steps:

[0019] 1) Introduce rural domestic sewage into the grid well, and enter the facultative pond after being filtered by the grid well;

[0020] 2) The treated water from the facultative pond enters the biofilter, which is filled with brush elastic filter material, the corrugated filaments of the brush elastic filter material are 160-200mm long and 2-5mm in diameter ;

[0021] 3) The water filtered by the biological filter enters the vertical flow constructed wetland. The substrate of the constructed wetland is a pebble layer with a particle size of 50-100 mm, a volcanic rock filter layer with a particle size of 15-30 mm, and a particle size of 8 -10mm biological filter material layer and a mud-free coarse sand layer with a particle size of 0.2-5mm, and the artificial wetland is planted with yellow flower iris;

[0022] 4) The water treated by the artifi...

Abstract

The invention relates to a rural domestic sewage comprehensive treatment method, which comprises the following steps of (1) introducing rural domestic sewage into a grid well to be filtered by the grid well, and then feeding the rural domestic sewage into a facultative pond; (2) feeding water treated by the facultative pond into a biofilter, wherein hair brush elastic filtering materials are filled in the biofilter, and the silk length of goffered silk of the hair brush elastic filtering materials is 160 to 200 mm, and the silk diameter is 2 to 5mm; (3) feeding water filtered by the biofilter into constructed wetland, wherein substrates of the constructed wetland are sequentially a pebble layer with the particle diameter being 50 to 100 mm, a volcanic filtering material layer with the particle diameter being 15 to 30mm, a boilogical filtering material layer with the particle diameter being 8 to 10mm and a mud-free coarse sand layer with the particle diameter being 0.2 to 5mm from bottom to top, and iris wilsonii is planted in the constructed wetland; (4) feeding the water treated by the constructed wetland into an ecological pond, wherein lotus, hornwort and water lilies are planted in the ecological pond; discharging outlet water treated by the ecological pond into natural water bodies. The method is applicable to scattered rural villages; the treatment effect is stable; the odor radiation and the breeding of mosquitoes and flies can be greatly reduced.

Description

technical field [0001] The invention relates to a comprehensive treatment method for domestic sewage in rural areas, belonging to the technical field of sewage treatment. Background technique [0002] With the rapid development of the rural economy, the discharge of comprehensive rural wastewater has gradually increased, which has deteriorating the environmental conditions in rural areas, and the environmental quality has declined significantly, directly threatening the living environment and health of the broad masses of farmers, and restricting the healthy development of the rural economy. . The random discharge of domestic sewage is the main cause of rural water environment pollution, which seriously pollutes the rural ecological environment and directly threatens the health of farmers and the economic development of rural areas. [0003] Rural domestic sewage in my country has the following characteristics: (1) Scattered and distributed in a large area. Scattered geogr...
