Abstract: The present invention discloses a tower-shape integrated ecological purification device for domestic sewage in a small town. The device includes a water storage and filter pond, a medium reverse osmosis pond, an amphibious biological reaction system, and an aquatic biological reaction system. The amphibious biological reaction system and the aquatic biological reaction system are alternately connected from the top down. The amphibious biological reaction system and the aquatic biological reaction system form an alternating dry and wet, oxidation-reduction compound environment. Plant absorption, biological substrate transformation, aeration, and strengthening medium adsorption are combined to form a multi-stage plant-microbe-animal integrated ecological purification treatment process/device. The present invention achieves the efficient purification and acceptable discharge of domestic sewage in small towns.
