Embodiment 1

[0023] like figure 1 As shown, the endless circulation landscape artificial wetland of this embodiment includes a main body 3, a partition 2, a wetland unit 7, and wetland plants. The main body 3 is made of cement material and needs anti-seepage treatment. The main body 3 is elliptical and consists of three wetland units 7 connected in series. Each wetland unit 7 is separated by a partition 2. Adjacent wetland units are connected through a perforated plate 5. The height of each wetland unit is lowered by 8cm step by step. Partition plate 2 can be made into solid wall with cement and brick and serves as. The first wetland unit is provided with a water inlet pipe 1, and the last wetland unit is provided with a water outlet pipe 6. Each wetland unit 7 can be adapted to local conditions, all using subsurface flow wetlands or all surface flow wetlands. If the subsurface flow wetland is used, the lower part of the substrate layer is filled with a gravel layer with a particle size ...

Embodiment 2

[0026] The non-terminal circulation landscape artificial wetland of this embodiment is as follows: figure 2 As shown, the difference from Embodiment 1 is that the main body 3 is square and consists of four independent wetland units 7 .

Embodiment 3

[0028] The non-terminal circulation landscape artificial wetland of this embodiment is as follows: image 3 with Figure 4 As shown, the difference from Embodiment 1 is that the main body 3 is circular and consists of six independent wetland units 7 connected in series. The 6 wetland units are alternately arranged in subsurface flow wetlands and surface flow wetlands to form a circular circulation mixed artificial wetland system of "subsurface flow-surface flow-underflow-surface flow-underflow-surface flow". Each wetland unit is composed of perforated plates 5 connected. Among them, the gravel layer 8 of the subsurface flow wetland unit is higher than the matrix layer of the surface flow wetland unit, that is, the mixture 9 of garden soil and yellow sand, and the top of the gravel layer 8 is covered with garden soil. Wetland plants 10 are planted on the pastoral soil and the mixture 9 of pastoral soil and yellow sand on the top of the gravel layer 8 .

Abstract

The invention provides an endless circumflex type landscape artificial wetland, comprising a main body, wetland units and wetland plants; the main body oval, square or round, and is formed by connecting individual wetland units in series; the wetland units are isolated by isolation plates; the first wetland unit is equipped with water inlet pipes and a mesh distributed with the water pipes; the last wetland unit is equipped with water outlet pipes; each wetland unit is an underflow artificial wetland, or surface flow artificial wetland, or a wetland arranged by alternating underflow artificial wetlands and surface flow artificial wetlands; the substrate layer of the underflow artificial wetland is composed of gravel and natural soil; the surface flow artificial wetland is composed of mixture of natural soil and yellow sand; and wetland plants are planted on the substrate layers of the wetland units. The invention saves occupied area, adds the procedure of sewage treatment, prolongs the retention time of water power, is free from blockage, has simple structure, convenient operation and maintenance, low investment and operation fee, and a landscape effect.

Description

technical field [0001] The invention relates to a small landscape artificial wetland, which is suitable for the treatment of domestic sewage in urban communities and belongs to the technical field of sewage purification. Background technique [0002] Constructed wetlands are artificially constructed, controllable and engineered wetland systems designed and constructed to treat wastewater through an optimized combination of chemical and biological actions in natural ecosystems. Constructed wetlands have the characteristics of good effluent quality, high nitrogen and phosphorus removal efficiency, convenient operation, maintenance and management, and low investment and operating costs. Constructed wetlands can be divided into surface flow constructed wetlands and subsurface flow constructed wetlands according to the way sewage flows in constructed wetlands. The surface flow constructed wetland is sewage flowing through the surface of the wetland, which has the advantages of l...
