Treatment method capable of reducing breeding of flies and mosquitoes for rural domestic sewage

Abstract

The invention relates to a treatment method capable of reducing breeding of flies and mosquitoes for rural domestic sewage. The treatment method comprises the following steps: 1) introducing the rural domestic sewage into a grid well, filtering the rural domestic sewage by the grid well and introducing the filtered rural domestic sewage into a facultative pond; 2) introducing water treated in the facultative pond into a biological filter, filling the biological filter with an elastic filter material made of high-molecular organic material, wherein the porosity of the elastic filter material is 75-98%, the bore diameter of the elastic filter material is 6-8 mm and the specific surface area of the elastic filter material is 10-35 m<2>/g; 3) introducing water filtered by the biological filter into a vertical-flow artificial wetland, wherein thalia dealbata is planted inside the artificial wetland; and 4) introducing water treated in the artificial wetland into an ecological pond, wherein water lily, vallisneria spiralis and pontederia cordata are planted inside the ecological pond, and outlet water treated by the ecological pond is discharged into a natural water body. The method is suitable for a dispersive village in the countryside, is stable in treatment effect, and can greatly reduce emission of bad smell and breeding of mosquitoes and flies.

Description

technical field [0001] The invention relates to a rural domestic sewage treatment method for reducing the breeding of mosquitoes and flies, 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 lar...

(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
