Embodiment

[0020] The rural domestic sewage treatment method with better performance of the present embodiment comprises the following steps:

[0021] 1. A method for treating domestic sewage in rural areas with better performance, comprising the following steps:

[0022] 1) Introduce rural domestic sewage into the grid well, filter it through the grid well, enter it for oxygenation, and then enter the three-phase biological fluidized bed after oxygenation. The distribution plate of the three-phase biological fluidized bed is stacked with activated carbon and fine quartz Sand, the effluent of the three-phase biological fluidized bed enters the facultative pond, and at the same time, part of the effluent of the three-phase biological fluidized bed flows back to the effluent of the grid well;

[0023] 2) The treated water in the facultative pond enters the biofilter, which is filled with elastic filter material made of polymeric organic materials, with a porosity of 75-98%, a pore size of ...

Abstract

The present invention relates to a rural domestic wastewater treating method having relatively good advantages. The method comprises following steps: 1) introducing rural domestic wastewater into a grating well, and discharging water after filtering by the grating well into a facultative pond; 2) discharging water treated by the facultative pond into a biofiltering pool, wherein the biofiltering pool is filled with elastic filler prepared from a high polymer organic material, the porosity is 75-98%, the aperture is 6-8mm, and the specific surface area is 10-35m2/g; 3) discharging water filtered by the biofiltering pool into a vertical flow artificial wetland, wherein thalia dealbata is planted in the artificial wetland; 4) discharging water treated by the artificial wetland into an ecological pond, and discharging water treated by the ecological pond into natural water, wherein water nymph, eel grass and pontederia are planted in the ecological pond. The method is suitable for being used in scattered villages in the countryside, the treatment effect is stable, and the bad smell emitting and the mosquito and fly breeding can be reduced greatly.

Description

technical field [0001] The invention relates to a method for treating rural domestic sewage with better performance, 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...
