Abstract

The invention discloses a three-dimensional vertical subsurface flow constructed wetland device, belongs to the fields of environmental sciences, environmental engineering, and water supply and drainage science and engineering, and relates to a three-dimensional vertical subsurface flow constructed wetland device used for advanced treatment of domestic sewage. The invention is characterized in that the three-dimensional vertical subsurface flow constructed wetland device comprises an upper layer water inlet water distribution channel 1, an upper layer constructed wetland left unit 2, an upperlayer constructed wetland right unit 3, an upper layer water passage 4, a middle layer water inlet water distribution channel 5, a middle layer constructed wetland left unit 6, a middle layer constructed wetland right unit 7, a middle water passage 8, a lower layer water inlet water distribution channel 9, a lower layer constructed wetland left unit 10, a lower layer constructed wetland right unit11, a lower layer total water outlet passage 12 and a water outlet pipe 13. The device can reduce a land occupied area and increase plant biomass, is strong in reoxygenation ability, and can fully present cological landscape functions, reduce the cost of pipe network construction, and reduce the risk of groundwater pollution.

Description

technical field [0001] The invention belongs to the fields of environmental science, environmental engineering, water supply and drainage science and engineering, and in particular relates to a three-dimensional vertical subsurface flow artificial wetland device which can be used for advanced treatment of domestic sewage. Background technique [0002] Constructed wetland is a controllable wetland system built to simulate the natural wetland system and function. It is a sewage purification process for biological treatment and ecological restoration of polluted water bodies. It consists of enclosure structures, artificial media, aquatic plants, Microorganisms, sewage and other components. Constructed wetlands can be divided into surface flow constructed wetlands and subsurface flow constructed wetlands according to the operating water level inside constructed wetlands. Subsurface flow constructed wetlands are more widely used due to their good operating environment and polluta...
