Method for treating rural sewage by combining artificial wetland and ecological pond

Abstract

The invention relates to a method for treating rural sewage by combining an artificial wetland and an ecological pond. The method comprises the following steps: (1) introducing rural domestic sewage into a grid well, filtering the domestic sewage by virtue of the grid well, and enabling the domestic sewage to enter a compatible pond; (2) enabling the water treated by the compatible pond to enter a biological filter tank, wherein the biological filter tank is filled with an elastic filter material made of a macromolecular organic material, a porosity is 75 to 98 percent, an aperture is 6 to 8 mm, and a specific surface area is 10 to 35 m<2> / g; (3) enabling the water filtered by the biological filter tank to enter a vertical flow artificial wetland, wherein thalia dealbatas are planted in the artificial wetland; and (4) enabling the water treated by the artificial wetland to enter an ecological pond, wherein water nymph, eel grass and Pontederia cordata are planted in the ecological pond, and discharging the water treated by the ecological pond to a natural water body. The method is suitable for scattered rural countries, stable in treatment effect and capable of greatly reducing scattering of odor and the breeding of mosquitoes and flies.

Description

technical field [0001] The invention relates to a method for treating rural sewage by combining artificial wetlands and ecological ponds, and belongs 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...

Problems solved by technology

(3) Low processing efficiency

[0004] At present, there are many domestic and foreign treatment technologies for rural domestic sewage treatment, and the names are also various. However, both natural treatment systems and biological treatment systems have the problems of single technology and unstable treatment effects. At the same time, the treatment range is also limited, which is easy Smells and breeds mosquitoes
