Abstract

The invention relates to an ecological treatment device for supplying recycled water to landscape water. The ecological treatment device comprises a pretreatment pond, an anaerobe pond, an artificial subsurface wetland, a biological filter and a landscape water pond. The anaerobe pond is connected with the pretreatment pond. An overflow weir is arranged between the anaerobe pond and the pretreatment pond, and overflow holes are formed in the overflow weir. The anaerobe pond outlet water of the anaerobe pond is connected with wetland inlet water of the artificial subsurface wetland. The artificial subsurface wetland is arranged around a residential district building. The wetland outlet water of the artificial subsurface wetland is connected with the biological filter inlet water of the biological filter. The biological filter outlet water of the biological filter is connected with the landscape water pond. The landscape water pond is arranged at the center or the low position of a residential district. The ecological treatment device treats domestic sewage of the urban residential district into landscape entertainment water; the device is arranged according to the terrain of the residential district, construction and management are easy, no power facility is needed during running, energy is saved, the device is environmentally friendly, efficient running of a wetland system is guaranteed, resources are saved, and the environment is beautified.

Description

technical field

[0001] The invention relates to the technical field of environmental engineering, in particular to the field of artificial wetland ecological treatment, and in particular to an ecological treatment device for replenishing landscape water with recycled water. Background technique

[0002] China is a country seriously short of water resources, and there are problems of lack of fresh water resources and increasingly serious water pollution. According to the 2011 national document, tap water is not allowed to be used for landscape water replenishment in residential areas. In recent years, many cities at home and abroad have purified sewage and reused landscape water for entertainment, which not only saves fresh water resources, but also beautifies the environment.

[0003] Landscape water replenishment and restoration technologies mainly include biofilm treatment technology, ecological bed technology, artificial wetland treatment technology, aquatic animal and p...
