Abstract

The invention discloses an ecological underground sewage treatment system which comprises an underground area and a ground area, wherein the ground area is arranged on the underground area, the underground area comprises a grating, an aeration grit chamber, a biochemical tank, a coagulating tank, a sedimentation tank and a disinfection tank which are sequentially connected through pipelines, and the ground area comprises a sunlight shed. The invention also discloses an ecological underground sewage treatment method. The whole sewage plant is more attractive, more ecological and more coordinated with the surrounding environment, meanwhile, the system can serve as an adjusting tank, water can be supplemented to the surrounding riverway according to needs, the system can also serve as a fire-fighting water tank, all structures in the underground area are designed in a common wall mode, and head loss and occupied land are reduced.

Description

technical field [0001] The invention relates to an ecological underground sewage treatment system and a method thereof, belonging to the technical field of water treatment. Background technique [0002] With the rapid process of urbanization, the fringes of urban areas continue to expand outwards, and the original suburbs gradually become urban areas. The relatively backward urban planning has caused some sewage treatment plants built earlier to be surrounded by cities. Regional conflicts are prominent in our country is very common. Compared with traditional sewage treatment plants, underground sewage treatment plants have the advantages of saving land resources, almost no odor, no noise, and can beautify the surrounding environment. At the same time, they can increase the use value of the surrounding land and expand the space for urban development. The effluent can replenish nearby water bodies, and can also reduce the construction cost of sewage and reclaimed water pipe n...
